Installation
Components
The 802 Terminal is 802.11b compatible operating between 2399.5 MHz and 2474.5
MHz using direct sequence spread spectrum; it works with Access Points that are
802.11b or 802.11g compatible (b is a subset of g). The components in your 802
Terminal system will vary according to the configuration of your system. Your R/F
Terminal shipment should contain at least:
•
An R/F Terminal T802 or LT802 (unit includes keypad and display).
If the R/F Terminal is an LT802 model, it will have an integrated laser
scanner built-in to the body of the terminal. Each terminal is shipped
with a shoulder strap, boot, and Manual.
•
An optional Scanner – if you ordered the T802 models instead of the
LT802 models with the built-in laser scanner.
•
•
Optional rechargeable batteries and a 9v power supply.
802 Utilities CD ROM – demo programs, Active X development
software, test program, and firmware loader program
Keep the shipping box for the R/F Terminal in the event it is necessary to
return equipment for repair later.
Installation Tips
1. Be sure all Access Points and Terminals have the same SSID and WEP
Key, (if Encryption is used). Terminals are shipped with a SSID of
WORTH DATA.
2. Start with one Terminal. Get everything working with the single
terminal and then add other terminals, being certain that all terminals
have unique IP Device Address.
3. Use the 802 Test Programs to validate that everything is working. If
you have problems, refer to the Trouble Shooting Section.
Using the RF Terminal keypad…
The R/F Terminal is turned on by pressing the green
ON/OFF button located in the upper left-hand corner
of the R/F Terminal keypad.
The R/F Terminal has a Shut Down Time feature that allows you to
determine the length of time the R/F Terminal must be inactive before
automatically shutting down to conserve battery power. When the R/F

Terminal shuts down, simply press the ON/OFF button to resume operation.
The keypad is custom designed for the R/F Terminal operations. It has
numeric and control keys in the non-shifted state, and alpha characters in its
shifted state. You can readily determine if SHIFT is on by the cursor on the
display. When upper case alpha SHIFT is on, the cursor is a large black
rectangle. When SHIFT is off, the cursor is a narrow underline character.
For all prompts which ask for a YES or NO response, the ENTER key, is
the YES reply, and the 0 (zero) key is the NO reply. As you key data, you
will see each character displayed on the screen. If you make a mistake, you
can delete the last character by pressing the DELETE key, or you can clear
all characters displayed on the screen by pressing the CLEAR key.
You can order NiMH rechargeable batteries (L01) from Worth Data along
with a 9v recharging Power Supply that recharges the batteries completely
within 2 hours. When recharging options (batteries or Power Supply) are
ordered with the Terminals, the Terminal's Batteries Setup parameter is set
for recharging "1" which allows the batteries to be recharged under program
control. Otherwise, the batteries shipped are non-rechargeable alkalines
with no recharging options set in the Terminal. However, you may change
the battery type yourself. Using NIMH or alkaline batteries, you should get
24 hours of operation (assuming 1 transaction every 8 seconds).
If you did not order the rechargeable batteries and you change to
rechargeables, you must change the Terminal's Setup to Batteries 1 to allow
recharging. If you want to charge the batteries without having to remove
them from the Terminal, you must use the Worth Data 9v power supply.
You can safely use alkaline batteries in a terminal set for recharging,
providing you don’t plug a power supply into the terminal. Recharging
Alkaline batteries may cause the batteries to explode and leak battery acid
throughout the RF Terminal. Battery acid damage is not covered by the
Worth Data warranty because it not deemed to be “normal use”.
If you are using alkaline batteries (either regular or rechargeables) and
have selected the Rechargeables setting in the Battery setup parameter (See
Chapter 2; RF System Setup), the RF Terminal will generate the following
error message:
Alkaline Batteries
Detected,

Battery Life Indicator
The R/F Terminal detects low AA batteries and displays the following message:
LOW BATTERIES
Finish, Sign Off
Change Batteries
Hit Any Key_
At this point you have approximately 2 minutes of operational time to finish
your transaction (or note where you are leaving off if in the middle of a
transaction) and sign off. After 2 minutes, the R/F Terminal displays:
CHANGE BATTERIES
UNIT SHUT DOWN_
This message displays for 20 seconds before the R/F Terminal signs off from
the host (if signed on) and then shuts itself down. If you turn it back on
without changing batteries, you may experience constant beeping, intermittent
scanning, and very irritating symptoms that look like equipment failure.
Once you remove the batteries, you have 5 minutes to change them before
you lose the date and time in the Real-Time Clock.
The R/F Terminal also has a battery life indicator. Press the STATUS key
to display the remaining battery life of the AA batteries (as well as the date,
time and other information) as follows:

parameters that are changed by keypad only. Shaded items are keypad access only.
Using the bar code RF Terminal Setup Menu
To use the bar coded Setup Menu, scan these bar codes in this order:
•
•
Start Setup - you should hear 2 beeps
Setup Parameter bar code (i.e. “Beep Tone”)-you should hear 2
beeps for each scan
•
•
Number bar code that corresponds to the appropriate setting
(i.e. “3” to change the Beep Tone to “high”) - you should hear 2
beeps for each scan
End Setup-you should hear 3 beeps after END SETUP.
2-2
Download from Www.Somanuals.com. All Manuals Search And Download.
More than one Setup Parameter can be changed before you scan END
SETUP. For example, if you scanned START SETUP, then “Beep Tone”,
then 3, then “Speaker Operation”, then 1, then END SETUP, this would
change the beep tone to “high”, and turn the speaker "off".
If you are using a Laser Scanner to setup the RF Terminal, the beam will
often cover more than one bar code. Cover any adjacent bar codes before
scanning, and then check the RF Terminal display to make sure the correct
setting was entered.
Using the keypad to setup the RF Terminal
The RF Terminal can be setup via the Terminals' keypad by entering Setup
Mode from the menu. Turn on the Terminal and press any key. You should see:

Automatic Check Back
This parameter should not be changed under normal circumstances. After
the host sends a prompt, the Terminal goes to sleep waiting on the operator
to key or scan input in response to the prompt. It waits until the Automatic
Shut Off time or until the operator responds. This parameter sets the time
that the Terminal stops waiting on input from the operator, discards the
current prompt, and goes back to the host to see if there is a change in
instructions. If no change, the host must resend the prompt again because
the Terminal has discarded the original prompt. The host now has the
opportunity to change a prompt. The time can be set in increments of 5
seconds, up to 495 seconds. The default value is 00. The values possible for
entry are 00-99. An entered 99 gives 99x5 seconds, or 495 seconds between
check backs. The Terminal sends back an ASCII 07 for the data back to the
host (ID ASCII 07 CR). This parameter's prompt is:

to your computer. The check digit is the last character and is based
upon a calculation performed on the other characters.
Setting C transmits UPC-E0 bar codes as is; setting D transmits them
with inserted zero’s to make them the same length as a UPC-A bar
code. A NSC of 0 is assumed. It is possible to read UPC-E1 bar codes;
by default this option is disabled. Do not enable UPC-E1 if you plan
on reading EAN-13 bar codes; you may experience partial reads when
reading EAN-13. The UPC-E1 option is set in the 2 of 5 Code

If you prefer to transmit UPC-E bar codes in a 6-digit format while EAN-
8 is transmitted in its original 8-digit format use setting F. This will
allow you to use settings 9 and A and still transmit EAN-8 as 8 digits.
UPC-A can be transmitted in EAN-13 format by adding a leading 0

2 of 5 is so susceptible to misreads that the RF Terminal adds an additional
safeguard - it can be configured to look for fixed-length data only.
The default setting of 06 causes the RF Terminal to read only 2 of 5
codes that are 6 digits in length. To set the RF Terminal to read a
different length, scan any two-digit number from the bar pad table. For
example, to change the RF Terminal to accept an 8-digit bar code, scan
0 then 8 from the bar pad table. 2 of 5 code must always be an even
number of digits so the length setting must always be an even number.

Double Decode is there to minimize the possibility of misreads when
scanning very poor quality bar codes. This option forces the RF Terminal
to keep reading until it gets two results that are identical. This "double scan
checking" takes longer but will minimize misreads since it must get the
same result twice before considering it a "good" read.
4-second laser beam increases the amount of time the laser beam is
activated, giving the laser more time to try and read a code. This
option is useful for trying to read poor quality code. Using the 4-
second laser beam with long range lasers give the operator more time to
aim the laser properly at a distant bar code (usually using the "marker"
beam). The default beam time is 2 seconds.

Aiming Dot Duration
This parameter applies to the built-in internal laser and the LZ200 and LZ400
tethered laser scanners. Before the laser beam spreads, you can create a brighter
aiming dot to be sure you are on the bar code you want to read. The default is set
to 00, no aiming dot. You can key in 01 through 99, which creates an aiming dot
in 1/10th second increments; i.e., 20 would be two seconds.

Chapter 3
Operational Theory
Before you jump in and start writing a complex host program, it might be nice to
be familiar with the theory behind the operation of your RF Terminal.
Basic RF System communications…
A WIFI RF Terminal system consists of three components – Host Server,
Access Points and RF Terminal. The Access Points are connected to the Host
Server by Ethernet wiring. The RF Terminal "signs in" by establishing
communication with a Server Program (located on the Host Server) through an
Access Point. After the RF Terminal "signs in", the Server Program can send a
prompt to the terminal with the ActiveX program interface provided by Worth
Data. The application running on the Host Server sends a data prompt to the RF
Terminal device to the Access Point (using the Ethernet wiring), and then by
radio link to the terminal device. The RF Terminal displays the data prompt on
the display and waits for the operator to enter the requested data. Once the
operator enters his data, the RF Terminal transmits the data to the Access Point,
which in turn passes it on to the Host Server. The application on the Host
Server processes the information and sends a new data prompt out to the Access
Point and the whole process begins again.
A little more in depth…
This RF system’s dialogue is Terminal initiated. The Terminal says, “I’m
here, give me something to do.
When you select DEVICE SIGN ON?, the RF Terminal first establishes
communication with the network as follows:
1. It looks for an Access Point with an identical SSID and WEP Key using
the Channel Number in its configuration as the starting channel.
2. If the terminal is configured to obtain its IP address from a DHCP
Server, it requests an IP address from a DHCP Server. If it requests an
IP address, the terminal will display:
Looking for DHCP Server,
Please Wait
3. If the terminal does not have a fixed Server IP address configured, it
does a search for an Application Server. While is searches for an
Application Server, the terminal will display:
Looking for App Server,
Please Wait
4. Now the RF Terminal sends a SIGN ON message to the application
Server. All messages include data as well as the transmitter's and
receiver's MAC address, IP address, and Port address.
3-1
Download from Www.Somanuals.com. All Manuals Search And Download.
When the Server receives a SIGN ON message from a RF Terminal, the
Server transmits the SIGN ON information to the host application program.
The host application can then do one of two things:
1. If it has something for the Terminal to do, it can send a prompt to the
Terminal. The RF Terminal receives the prompt, waits for the
operator to enter the requested data, and then transmits the data back
to the application program.
2. If the host program does nothing within 2 seconds, the Terminal
displays the message:
WAITING FOR PROMPT
FROM HOST COMPUTER
Lets suppose that a RF Terminal and a host application program have been
processing data by sending prompts and data back and forth as described in
example 1. The host application program sends a data prompt to the RF
Terminal. The RF Terminal transmits the operator-entered data back to the
Server. If the host application program has another prompt for the
terminal, it sends it out, repeating the process above.
If the host application program doesn't respond within 2 seconds, the
Terminal Device displays
WAITING FOR PROMPT
FROM HOST COMPUTER
until the prompt is received.
If the Terminal gets no response after 3 transmissions, it will perform an
Access Point scan. If it fails to get a good signal from an Access Point with
matching SSID and WEP Key, it will display the message:
TERMINAL OUT OF RANGE
PRESS ANY KEY TO RETRY_
You might walk closer to an Access Point or you might simply hold the
terminal up high over your head. When you have repositioned the terminal,
pressing a key on the Terminal starts the transmission process over again.
If the Access Point scan finds a satisfactory Access Point, the Terminal will
display the message:
SERVER NOT AVAILABLE
HIT ANY KEY_
This tells you that the Application Server host program is not running. If
you press a key, you will be transferred to the mode menu where you can
chose to Sign On again.

Can I change a prompt after it has been sent?
Normally once the Terminal has received a prompt from the host, it goes to
sleep and waits (as long as it takes) for the operator to scan or key
something in response. The host cannot send another data entry prompt
without creating a "Sequence Error." However, you might want to change
the prompt to a slow operator or even locate a lost terminal with beeping.
You can do this using the "Automatic Check Back" option. You set a
predetermined interval (in increments of 5 seconds) of when you want the
terminal to send back a message "do you have a change for me?" If there is
no change, you simply resend the original prompt; if there is a change, you
send the changed prompt. (See Chapter 2, Automatic Check Back).

Performance Issues
Evaluating your area of planned operation
Since every operational environment is different, it is impossible for us to
tell you exactly what equipment you need and where you should put it to
achieve maximum performance from your RF System. However, since
access points are very inexpensive, you should be able to obtain whatever
coverage you need. In a typical warehouse, a terminal should be able to
achieve communication within about 150 feet of an access point. If you are
planning the wiring of a new installation, you will want to lay out your
access points so that there is overlap.
Below is a 300 ft. by 500 ft. warehouse area with access points positioned
to provide planned coverage over the entire area. You do a site test by
positioning one access point in each location and verifying that the
projected area of coverage is actually attained. (You don't have to be
connected to the network to do this site test; you only need to supply power
to the Access Point).
If you have difficulty somewhere in the area, as long as that area is in an
area of overlapped coverage that a different position of the Access Point
4-1
Download from Www.Somanuals.com. All Manuals Search And Download.
covers, you won't have a problem. If you find a spot that none of the
planned Access Point locations will cover, you will have to move one of the
Access Points closer to the problem spot or plan on adding another closer
Access Point. It is best to locate the Access Point in the center as high as
possible of the area you intend coverage. The weakest signal will be directly
under an access point, (if the antenna is vertical).
Avoid locating antennas close to large metal objects such as filing cabinets,
microwave ovens, 2.4GHz cordless phones, or large containers of water.
Avoid placing antennas close to an outside wall to minimize signal
efficiency. If you need to have coverage outside, place it next to a window.
Once you have determined the Access Points and their locations, you are
ready to wire the Access Points to the LAN.
To perform a Site Test, turn the unit on and press any key to go past the
opening screen and get to the "Mode Menu" which displays as follows:
DEVICE SIGN ON ----->1
SETUP MODE----------->2
SITE SURVEY----------->3
Press the 3 key to start the Site Survey.
The terminal will do an Access Point Scan and report on the three Access Points
with the strongest signals contacted, (or fewer than three is less contacted). The
display will be updated every two seconds and have the following format:
ACCESS POINT SCAN
---SSID---
CHAN

HIT F1 TO EXIT
Access points without a matching SSID will not be shown, unless the
Terminal's SSDI is blank. If no Access Point can be located, nothing will show
below the headings.
The "SIGNAL" number on the right that can vary from 0-100, with 100
being best. You have adequate signal strength at 20. If you have less than
20, you need to move or add an Access Point. Typically it operates in the
50% range. (50% is not bad; the radios on the Access Points and the
Terminals drop power to conserve batteries and to minimize interference).
Remember when doing a site test in a warehouse, as the contents of the
warehouse change the interference changes too. So if you have a marginal
signal on the Site Survey, it may turn into poor performance later.
There is also some basic information about Radio Frequency itself that can help
you make smart choices about the location and composition of your system:
•
Metal walls are almost impenetrable by RF. If your warehouse
4-2
Download from Www.Somanuals.com. All Manuals Search And Download.
computer is located in a metal shed, you will need at least one Access
Point located outside the metal shed.
•
•
The more walls you try to transmit through, the more the signal
breaks down. Walls that have metal studs (interior office walls)
and concrete walls with steel rebar slightly degrade the signal with
each wall you try to go through. Metal walls may require the use of
Relay Stations to achieve adequate coverage.
Organic material absorbs RF energy. If you are trying to operate in
an area with lots of densely packed organic material (bags of beans or
corn), expect and plan for reduced operating ranges.
Raise the Access Point. Sometimes just raising the Access Point 12 feet
will dramatically increase your operating range, especially in a warehouse
or grocery store environment. Mounting the Access Point on the ceiling
with the antenna pointing vertically (up or down) is the best.

Chapter 5
Before you begin programming…
The “Application Host Program” or “Server Program” is a program designed and
written by the user that incorporates the WD802Term ActiveX control. When an
802 RF Terminal is turned on and “Signs In” to the host, the WD802Term control
reports a terminal ID number to the host application that is unique to that terminal.
The IP address of a particular terminal can also be obtained.
Once an 802 RF Terminal is signed in, it receives messages from the host user
program. The terminal responds back to the host application program with data that
was keyed or scanned by the terminal's user. The host application program processes
the data and sends back the next prompt. Each 802 RF Terminal has a unique IP
address (or at least a unique Mac address). The host program can obtain any
terminal’s IP address or, for the sake of compatibility with programs written for
70/700 series terminals, resolve terminal addresses to a single character Terminal ID
(0-9,A-Z, a-z, and -=) by using the WD802Term ActiveX component.
The dialog between 802 RF Terminal and Application Host is established when a
terminal connects to the 802.11 RF network. The host computer application waits
until a terminal SIGNS ON, then begins its processing by sending the first prompt
out to the terminal via an 802.11/b Access Point.
Before you begin programming, there are some factors you should take into
consideration during the planning process.
•
•
Plan for system failures. This includes hardware failures,
software failures and operator failures. In order to create an
efficient application, you must put some thought into what you will
do when different parts of the system fail.
Look for All Errors. Be sure your program is trapping all possible
error conditions that the Server may return to you. The list includes:
Sequence Errors detected
Illegal Command detected
Server Re-Initialized
Addressing a Terminal Not Signed In
Command without an ID
All of these error conditions are detailed in the next chapter. Don’t
forget to program for them; this is a common mistake. Failure to
trap them will give create very strange, unpredictable results.
Even though you don’t think your code will ever make a mistake,
take advantage of feedback that the Server provides. Failure to do
so is a common mistake that eventually results in serious program
failure, sometimes due to hardware problems that go undetected.

•
Parse the Returned Strings thoroughly. Don’t assume anything
about the next response from the Server to your program and look
only for the partial string such as the ID only. Parse the string
returned completely, and be sure you are examining every
possibility. Failure to do so is a common mistake.
•
•
Plan for expansion. You may start small (1 Terminal) but try to
create an application that will allow for easy expansion.
Use the Test Program. The test program can at least allow you to
see how the system functions and whether you can anticipate any
system-wide problems. The test program should also be used as a
response-time benchmark.
•
Study the Demo Programs. Demo programs are included for
examples of how to use the ActiveX tool provided.
Failure Planning
Hardware Failures
Let’s assume that each part of the system has failed. How are you going to
know what has happened and how are you going to recover?
•
The most frequent failures are at the Terminal level. If a Terminal has
a hardware failure, it will not be able to SIGN OUT. It is possible for
the Terminal operator to press the ON/OFF key or the F1 key by
accident, forcing the Terminal to SIGN OUT - sometimes in the
middle of a transaction. This happens at battery-changing time also.
You need to plan for partial transactions - do you trash the data you do
have and start over, or pick up where you left off?
•
Keep in mind that if a Terminal has SIGNED OUT in mid-transaction,
the Server clears any pending message for that Terminal before it will
allow it to SIGN ON again. Make allowances to re-send messages or
prompts that were cleared upon SIGN ON if necessary.
Operator Errors
•
Plan on your operator walking out of range and going to lunch in
the middle of a transaction. What do you do with the data you do
have, and where are you going to start up again?
•
Let’s say your operator is SIGNED ON and decides it’s time to take a
break. Instead of pressing the F1 key to SIGN OUT, he presses the
OFF key. Pressing the OFF key is OK (it will SIGN him OUT) but
there is a delay until the SIGN OUT is acknowledged. Because of the
delay, the operator might think he didn’t press the key hard enough
and press it again - this time actually powering down the Terminal
before the SIGN OUT was complete. If this happens, you need to plan
to re-send the last prompt to the Terminal when he SIGNs ON again.

Programming for the 802 RF Terminal
The programming support offered for the 802 RF Terminal is an ActiveX drop-
in component. Every necessary function is defined - you just complete the code
for each function.
The ActiveX component functions as a Server for managing data traffic to and
from one or more terminals (your “terminal network”) and as an interface for
your host application. There is no other software required, besides this control
and your host application, to run a terminal network.
Introduction
It is important to note that creating working programs for the 802 Terminal requires
significant programming skills. In order to create a working application you will not
only need to be familiar with a programming language such as Visual Basic or
Delphi or C++; you will need to be experienced and comfortable building real
applications with one of these (or similar) programming environments.
You should be familiar with the concepts of objects, methods, event handlers,
properties, scope, arrays, pointers, variable and value parameter passing, etc.
Database connectivity, data structures, and state management techniques are key
to creating a program that can work with multiple terminals.
If you do not understand the references mentioned here and the implications of the
pseudo code illustrations, you may not have the skills necessary to create a working
application using the 802 Terminal WD802Term ActiveX programming tool.
What follows are just examples to get you started and show some basic
technique. There are lots of different ways to do this and it is possible to create
sophisticated transactions that intelligently instruct the terminal operator and
collect complex data.
Objects, Properties, Methods, and Events
The programming model for the 802 Terminal is based on the WD802Term
ActiveX component. This component is an "object" that is embedded in
your application that you build using a compatible programming
environment such as Visual Basic or Delphi.
The WD802Term "object" has a number of methods, event handlers, and
properties that it publishes (makes available) to your program.
Properties are generally initialization and configuration settings that you
set once when your application starts. Examples are ServerActive and
LogFileName.
6-1

Methods are how you initiate communication with the WD802Term object.
You can request that a prompt be sent to a terminal, map a terminal ID to an
IP address, and a variety of other services.
Events are how the WD802Term object initiates communication with your
application. You write "event handlers" in your program to respond that
respond appropriately when WD802Term "fires" an event that activates its
associated event handler. Examples are OnTermSignIn and OnTermData.
Creation of the source code "shell" for an event handler is generally handled
by your development environment (IDE for Integrated Development
Environment). For example, in Delphi, simply double click in an event field
in the Object Inspector; or in VB, from the source code window, select the
Object from the pull down list at the top left and then click on the desired
event in the Procedures pull down list at the top right.
You will notice that the IDE creates a "skeleton" function (or procedure or
sub) in source code that will include any parameters required to retrieve the
data delivered to the event handler by the WD802Term object.
It is your job to add functionality to the skeleton event handler that is
relevant to your application. It is important to remember to keep event
handlers short and efficient. Do not make method calls to WD802Term
from within a WD802Term event handler. Instead set up a state
management and polling or threading scheme as outlined below.
Signing In, Data Structures, Transactions, and State
Management
When a terminal SIGNS ON, it sends a signal to your application via the
WD802Term object, which fires the OnTermSignIn event. When the event
fires, the terminal has already been assigned an ID number by WD802Term
and this ID number is passed to your application in the event handler.
Once it has signed in, the terminal is now waiting for your application to
make a call to one of WD802Term's methods that sends a prompt to the
terminal. Keep in mind that it is important to keep event handlers short and
to try to avoid making method calls from inside an event handler. This
brings us to transactions, state management, and data structures
Generally, you will have some kind of transaction process that you will
define. Typically a transaction would be defined by a series of prompts and
the data returned in response to the prompts.
Here is an example of a series of prompts that represent a transaction. When
a transaction is completed, it repeats as controlled by the host application
Go to location XX
Press enter when ready:
6-2
Download from Www.Somanuals.com. All Manuals Search And Download.
Pick Item YY qty N
Scan barcode:
Enter Qty Picked:
Of course you can see how you might handle incorrect items or wrong
quantities by having your application generate prompts such as
Incorrect Item
Scan correct item:
Too many items
Pick item YY qty N
Enter Qty picked:
These are just examples and there are other ways to design a transaction of
this sort. The point is that you will need to create a data structure that
defines the transaction and another data structure that keeps track of where
in the transaction each terminal is (state management), independent of any
other terminals that might be active.
You will need to create a data structure or record of some sort that keeps
track of each terminal's state. The structure might keep track of where in a
transaction process a terminal is; any pending data from, or prompt for, the
terminal; and any other information that is relevant to a terminal in the
transaction process you have defined.
An easy way to create a data structure for each terminal is to define an array
of User Defined Type (VB) or Records (Delphi) or Structs (C++). The array
would be large enough to accommodate all of your terminals (one array
element for each terminal) and might look something like this in VB
Type TermData
TermID as integer
TransactionIndex as integer
PendingPrompt as string
PendingData as string
ErrorCode as integer
Transaction as TransactionData
Etc.
End Type
dim Terminals(25) as TermData
You will also need to define a transaction. Typically the transaction is
applied to all terminals so it is a single structure (there is not a copy for each
terminal)
Type TransactionElement
commandcode as integer
promptline1 as string
6-3
Download from Www.Somanuals.com. All Manuals Search And Download.
promptline2 as string
promptline3 as string
NextIfError as integer
NextIfOK
End Type
as integer
dim TransactionSequence(10) as TransactionElement
TransactionSequence(1).commandcode = 1 'InputAny
TransactionSequence(1).promptline1 = "Go to Location " +
GetLocationCode
TransactionSequence(1).promptline2 = "Press Enter When
Ready "
TransactionSequence(1).NextIfError = 1
TransactionSequence(1).NextIfOK = 2
Etc.
As mentioned above, it is important to keep your event handlers short and
efficient. This means that your program should spend as little time as
possible "inside" the event handler (running the handler's code). Also, it is
important to NOT call WD802Term methods from inside WD802Term
event handlers. So a solution is needed that allows your program to respond
to events outside of the event handlers.
An easy way to do this is with a polling scheme. Add a timer object to your
application and in the timer's event handler check the TermData structure
for the state of each terminal and make any appropriate WD802Term
method calls from within the timer object's event handler. The timer can be
set to fire every 100 milliseconds or every 10 seconds or anything in
between that is appropriate for your application.
Another, more advanced way to decouple the WD802Term method calls
from the event handlers is using threading techniques where each terminal
is "running" in a thread that monitors that terminal's state.
WD802Term/ActiveX
WD802Term is a drop in ActiveX component that allows programmers to
easily add the ability to send prompts to and receive data from their R/F
Terminal across a wireless 802.11b Ethernet network connection.
The ActiveX component is compatible with Visual Basic, Visual C++,
Delphi, and most other 32-bit development platforms.
Programming Considerations
Remember, plan for every error that the Server might return including:
Sequence Errors detected
Illegal Command detected
Addressing a Terminal Not Signed In
6-4
Download from Www.Somanuals.com. All Manuals Search And Download.
Programming languages that can interface with the Active X tool include
VB, C++, Delphi, Access, FoxPro, etc.
If the Application Server receives any of:
1. 5 Addressing a Terminal not SIGNed ON messages in a row or
2. 5 Sequence Errors in a row, or
3. 5 illegal commands in a row,
the Server transmits the following message to the Terminal and shuts down:
Server Shut Down
Due to Host Logic
Error
Check your program to correct these errors before starting again. The host
application program will have to restart and you will have to cycle power on
the Terminal and SIGN ON again in order to continue.
Network Setup
•
The network settings on the server must support TCP/IP
communications.
•
It is critical that the Terminal(s) and Server are "visible" to each other
across your network. Both must have an IP address in the same
subnet. Both the Server and the Terminal Device(s) can either have a
static address or use an assigned IP address via a DHCP server or
equivalent. Refer to your Windows networking administration utility
in the Control Panel to configure computer IP address settings.
•
•
WD802Term uses port 54140
You can link server and terminal through a dial-up or DSL internet
link as long as the server has a static IP address and your router
passes the above port.
•
If you are unsure of how to set up your IP configuration properly,
refer to your network administrator for help.
Server Communications
•
Run the 802 Test Program on the server computer. Now go to an 802
RF Terminal and attempt to SIGN IN to the 802 Test Program. If the
terminal connects and responds with a prompt “Enter Data”, you are
configured properly. Go to the server computer, shut down the 802
Test Program and begin work on your WD802Term server
application.
•
Before making any WD802term method calls in your application,
make sure to turn the Server on by calling
WD802Term.InitializeServer
WD802Term.ServerActive = True

Test For Good Communication
•
Implement an event handler for OnTermSignIn that causes a beep or
displays a message when called. If communication between the host
PC and the terminal is good, your event handler will fire when your
program is running and you sign in a terminal on your network.
Terminal Tracking
•
Since you get only one set of event handlers, you will need some
scheme for keeping track of where each terminal (up to 1000) is in its
transaction sequence. Remember, WD802Term will give you a unique
ID number for each Terminal that signs in and that number is “locked”
to that Terminal until it signs out. One possible solution is to use a
"state" variable for each terminal (perhaps stored in an array). Test the
state variable to determine the next prompt for any given terminal. See
the samples for more ideas.
•
It is very important to keep track of "login status" for each terminal.
Every SignOut event should have an associated SignIn event and a
given terminal should not be allowed to SignIn twice without and an
intervening SignOut. Multiple SignIns from one terminal without
appropriate SignOuts indicate either:
1. A terminal going out of range and having its power cycled
before returning within range OR
2. Two (or more) terminals using the same IP address
(terminal ID conflict).
Control Keys for Possible Programming
There are some keys on the 802 RF Terminal keypad that when pressed, can
transmit special ASCII characters back to the host program. This feature might
be used by a programmer to allow the operator to review transactions. You can
use these keys for special program functions, such as scrolling thru data,
backing up steps, jumping, finishing a process, etc The keys are as follows:
Key
UP ARROW key
DOWN ARROW key
LEFT ARROW key
RIGHT ARROW key
BEGIN key
Code transmitted to Host
FS (ASCII 28)
GS (ASCII 29)
RS (ASCII 30)
US (ASCII 31)
ETB (ASCII 23)
CAN (ASCII 24)
VT (ASCII 11)
END key
SEARCH key
The STATUS key is reserved to only display the Time and Date.
The Control keys can be used without pressing the ENTER key by using the
Control Keys Only Terminal Setup parameter. See Chapter 2; RF System
Setup for details.

Concepts – WD802Term ActiveX
Drop-in components are tools that are added to your programming
environment "tool kit". Only the ActiveX variety are widely compatible
with almost all development environments. When you use drop-in
components in your program you will follow the standard object-oriented
programming paradigm that uses properties, methods, and events to
implement the functionality of the drop-in component.
Properties are the various configuration variables used by the drop-in
component. An example of a property is the ServerActive setting.
Methods are function calls used to issue commands and access features of
the drop-in component. An example of a method is sending an Input
command to the terminal.
Events are function definitions placed in your application’s source code.
The function definitions in your source code are called Event Handlers. The
skeleton structure of the event handler’s source code is automatically
generated. The code in the Event Handler is called ("fired") by the drop-in
component when a specific event occurs. An example of an event is when a
terminal returns data and the OnTermData event is fired.
The details of how to access Properties/Methods/Events varies between
development platforms. Details of how it works in some of the most popular
platforms is illustrated in the samples included with the RF Utilities CD or
available for download from our website at www.barcodehq.com
Properties – WD802Term ActiveX
Properties are the various configuration variables used by the WD802Term
control. They are directly assignable in your application (eg.
"WD802term.ServerOn = true") and can be set in your development
environment’s object browser.
Note that your development environment may show more properties for the
WD802Term control than are listed here. This is normal. You may ignore pro-
perties you see listed in your development environment that are not listed here.
ActiveTerminal
Valid values: 0-999
Function:
This is the terminal ID (0-999) to which method
call instructions are directed.
Terminal ID "number" is mapped to actual terminal
IP address dynamically.
See method "GetIPAddress" to get terminal IP
address associated with an ID.
6-7

Keep in mind that unless your terminal is configured
with a static IP address, each time it is powered on it
can have a different IP address (issued by your DHCP
server). Also, regardless of the terminal’s IP address, it
can be assigned a different ID (by WD802Term) each
time it Signs On to the server. Keep this in mind and
design your application accordingly if you require
specific physical terminals to perform specific
individual tasks.
ServerPort
Valid values: 5000-65536
Function:
These are the IP ports used by WD802Term to pass
command information to and from each terminal. This
setting must match the PORT setting in all terminals
used with this host application. Do not use port values
less that 5000. If you are not familiar with IP ports,
leave this value at the default setting.
ServerActive
Valid values: True, False
Function:
Set ServerActive to True to begin listening for
terminals. Before setting to True, be sure to call the
InitializeServer method (See Methods)
LogFileName
Valid values: Any valid file path and name
Function:
Leave blank if you do not want a log file kept. If you
enter a filename here, WD802Term will create the file
(or add to it if it already exists) in standard text file
format that you can open using Windows Notepad.
LogFileSize
Valid values: 1000 through 2GB (2000000000)
Function:
This is the maximum log file size that WD802Term
will keep. If the file exceeds this size, the oldest
entries are removed to make room for new entries.
Quiet
Valid values: True, False
Function: If Quiet is set to True then any status and error
message generated by WD802term will be
suppressed.

Methods – WD802Term ActiveX
Methods are commands that you issue to the WD802term control. All of
the "Inputxxx" commands cause the terminal to wait for operator input.
Note that your development environment may show more available methods
for the WD802term control than are listed here. This is normal. You may
ignore methods you see that are not listed here.
InitializeServer
Parameters: none
Function:
Prepares the Server to be started. Follow this call by
setting the ServerActive property to True. This must
be called before any of the methods described below.
InputAny
Parameters: line, position, prompt, shifted, timestamped
Function:
This instructs the ActiveTerminal to display the
prompt at line and position and wait for data to be
entered from either terminal keypad or scanner. If
shifted is set to "true", the terminal will start in
shifted mode. Timestamped appends a (hhmmss)
prefix to the returned data.
InputKeyBd
Parameters: line, position, prompt, shifted, timestamped
Function:
This instructs the ActiveTerminal to display the
prompt at line and position and wait for data to be
entered from the terminal keypad only.
InputExtKeyBd
Parameters: line, position, prompt
Function:
This instructs the ActiveTerminal to display the
prompt at line and position and wait for data to be
received from the PS/2 keyboard attached using an
adaptor to the terminal serial port. Waiting for
external keyboard input can be bypassed by
pressing the enter key on the terminal which will
send an empty data string to the host (fires the
OnTermData event handler). External keyboards
are supported by terminals using firmware version
RFU1010 or later.

InputScanner
Parameters: line, position, prompt, allowbreakout, timestamped
Function:
This instructs the ActiveTerminal to display the
prompt at line and position and wait for data to be
entered from the terminal scanner only. Setting
allowbreakout to true allow user to "breakout" of
scanner only mode by pressing the end key on the
terminal. A termID+CR will be sent to the host.
InputYesNo
Parameters: line, position, prompt
Function:
This instructs the ActiveTerminal to display the
prompt at line and position and wait for a Yes
(Enter key or C key) or a No (0 key or B key) from
the terminal keypad.
Note: C and B keys are used to facilitate keypad
entry while scanning with the integrated laser.
InputPassword
Parameters: line, position, prompt, shifted
Function:
This instructs the ActiveTerminal to display the
prompt at line and position and wait for data to be
entered from the terminal keypad only. The entered
data is not displayed on the terminal.
InputSerial
Parameters: line, position, prompt
Function:
This instructs the ActiveTerminal to display the
prompt at line and position and wait for data to be
received through the terminal serial port. Waiting for
serial input can be bypassed by pressing the enter key
on the terminal which will send an empty data string
to the host (fires the OnTermData event handler).
InputMagStripe
Parameters: data
Function:
This command is for a printer initialization and
magstripe input on the Zebra Cameo printer
equipped with the magstripe option.
This instructs the ActiveTerminal to send the string
data to an attached Cameo printer with the
magstripe option and wait for data to be received
through the terminal serial port. Waiting for serial
6-10

input can be bypassed by pressing the enter key on
the terminal which will send an empty data string to
the host (fires the OnTermData event handler).
Data might be
! U1 MCR 80 T1 T2+ CR + LF
(Refer to the Cameo manual for the exact string
sequence you need to send.
The above example sends over a 10 second request
for reading Track 1 and Track 2). There is no reply
to the host except the magstripe data.
OutputSerial
Parameters: data
Function:
This instructs the ActiveTerminal to send data to the
terminal’s serial port. Data must be less than 232
characters in length for each call to OutputSerial. If
you are sending data to a printer attached to the
terminal, make sure to set the Protocol parameter in
the 802 RF Terminal to XON/XOFF. See the 802 RF
Terminal Manual for details.
Special Considerations:
•
After an OutputSerial call is successfully completed, the terminal
will return (as data) a CR (ASCII #13 Carriage Return). This will
fire the OnTermData event. If there is a problem with the serial
data you will see an error message at the client and in the log (if
enabled). If the data string is too long, the
OnTermIllegalCommand event will be fired.
•
•
•
•
Do not call OutputSerial for the Terminal again until a return
code is received.
Do not call an Inputxxx method for the same Terminal until a
return code is received.
If you need to send more than 232 characters, send the first part,
wait for the acknowledge (#13) and then send the next part.
Calls to OutputSerial cannot be combined with other method calls.

Events – WD802Term ActiveX
WD802term events occur when a specific condition is met. When an event
is "fired", an event handler function in your application is called.
Though the details of exactly how it is done varies from one programming
environment to the next, the source code skeletons for the various event
handlers are automatically generated and inserted into your source code for
you. See the samples for more specific information.
Each event passes relevant information to your event handler function. For
example, OnTermData passes the data that was keyed or scanned into the
terminal.
Terminal ID is always passed as 0-999.
Once you have the event handler skeletons, you can proceed to add
whatever functionality you desire to each event.
Before any WD802term events will fire, you must make sure to turn the
Server on by calling
WD802Term.InitializeServer
WD802Term.ServerActive = True
OnServerActivate
Data passed: none
Event:
Called when the ServerActive property is set to
True immediately after the Server begins listening
for terminals.
OnTermSignIn
Data passed: terminal
Event:
A terminal has signed in. Terminal ID is passed in
terminal.
OnTermSignOut
Data passed: terminal
Event:
A terminal has signed out. Terminal ID is passed in
terminal.
OnTermData
Data passed: terminal, data
Event:
A terminal has sent data in response to an Input
method call.

OnTermNotSignedIn
Data passed: terminal
Event:
A command has been sent to a terminal that is not
signed in.
OnTermSequenceError
Data passed: terminal
Event:
The one-for-one host prompt/terminal response
protocol has been violated. The host cannot send a
second Input command until it has received a response
from the first Input command. If WD802Term
receives 5 sequence errors in a row, a Host Logic error
is generated and the server shuts itself down.
While WD802Term/ActiveX will intercept and prevent most logic
errors, they are still possible so you should implement this event
handler!
OnTermIllegalCommand
Data passed: terminal
Event:
An illegal command has been sent to a terminal.
WD802Term /ActiveX is designed to prevent illegal commands but
software is not always perfect and we may not have imagined all
the ways in which our customers will want to use it!
OnTermUpArrow
Data passed: terminal
Event:
The up-arrow button has been pressed on a
terminal. You must issue another Input method call
before WD802Term can respond to another
keypress on the terminal. If you have already
entered some data on the terminal and press an
arrow key, this event will not fire.
OnTermDownArrow
Data passed: terminal
Event:
The down-arrow button has been pressed on a
terminal. You must issue another Input method call
before WD802Term can respond to another
keypress on the terminal. If you have already
entered some data on the terminal and press an
arrow key, this event will not fire.

Portable Printers
Cameo and QL 320 Common Information
Both of these printers are stocked by Worth Data for the convenience of our
users who need portable printing.
These printers do not require any special protocol; they do not require the
“wake-up byte” as do other printers. They do require a special cable that
can be ordered from Worth Data (part #C12); cable pin-outs are available in
Appendix C: Cable Pin-outs.
Shipped with every Cameo or QL 320 printer ordered is a CD ROM with
the Programmers Manual in PDF format and a label design program –
LabelVista. This program allows you to design the program and create
multiple format files that can be sent to the printer where they become
resident in flash. Variable fields are defined and can then be filled in by the
program when in operation.
Keep in mind the following information when using these versatile printers:
•
•
The printer turn on ("Wake-up") is accomplished by the 802 RF
Terminal toggling the DSR line on the printer, so only the @S
command and the data you are sending to the printer is needed.
Once the 802 RF Terminal has turned on the printer, it stays on
until the host program turns it off using the POWER OFF
COMMAND "ESC(0x1b)`p'(0x70)" described in the Printing
Systems Programming Manual, or until the automatic shutdown
takes place (2 minute default).
•
The 231 character limit applies to your command string. See your
Portable Printing Systems Programming Manual for details on
programming your printer.
Zebra Cameo Printer
The Zebra “Cameo ” Printers are portable direct thermal receipt printers,
(not label printers – the QL 320 below prints labels). Bar codes can be
printed on the receipts, but you can’t print labels.
One model of the Cameo printer is available with a magnetic stripe reader,
allowing magnetic stripe input to the 802 RF Terminal using the @M
(magstripe input) command.
•
The Cameo printer with magstripe input is capable of reading
Track 1, Track 2 or Tracks 1&2. See your Portable Printing
Systems Programming Manual for the correct character string to
send in the @M command to turn on the magstripe reader. (see
page 6-2 for details).
6-17

•
When the Terminal sends data to the host, it sends it in the
following format:
Terminal ID + DATA + CR
Typically, the data is simply a string of characters, but in the
instance of data coming from the magstripe reader, there are some
additional characters you need to be aware of. The magstripe
reader sends its data in the following formats:
Track 1:
T1: DATA
Track 2:
T2: DATA
Track 1&2:
T1: DATAT2: DATA
So, when the 802 RF Terminal transmits the data to the host, it will
be in the following format:
Terminal ID + T1: DATA + CR
or
Terminal ID + T2: DATA + CR
or
Terminal ID +T1: DATA + T2: DATA + CR
For further information, see your Printing Systems Programming
Manual on the CD ROM shipped with the printer.
Zebra QL 320 Printer
The QL 320 Printer is used for label printing. It doesn’t have Magstripe
input. The classic application is for printing shelf labels during shelf price
verification:
1. The operator scans a shelf label.
2. The Terminal transmits scanned data to the host computer.
3. The host computer looks up the price, description, etc. and
transmits the computer price back and sends the necessary
commands to the attached QL 320 printer to prints a new shelf
label with the correct price.
4. The terminal operator then peels off the label and applies it to the
shelf.
Each printer is shipped with a no charge roll of thermal paper that can be
used for development, including determining the exact label size that best
fits you needs and the capabilities of the printer.

Chapter 7
Voice Message Operations
The 802 RF Terminal’s exclusive use of voice prompts allows you to overcome
problems such as literacy, language and lighting. With proper planning, voice
prompting can enhance your 802 RF Terminal application, making it faster and
simpler. Voice messages are recorded in the 802 RF Terminal, and then
triggered by a prompt from the host computer.
Why Use Voice Messages and Prompts?
•
•
•
Voice messages can be in any language.
The operator does not have to be able to read to perform some jobs.
Audible instructions can be heard in poor lighting where it is
difficult to read a LCD screen. MOST IMPORTANTLY, the data
collection process is faster because the operator does not have to
continually look at the screen for instructions. This is especially
useful when you do not want or need to enter data from the
keypad. Scanning bar coded numbers from a Quantity BARPAD
can make keying unnecessary.
Voice messages and prompts are a good way to keep the operator’s
attention focused on the job at hand. Audible error messages and warnings
also help to limit mistakes and downtime.
Tips for Using Voice Prompts
Over 90 voice messages can be recorded in the 802 RF Terminal. Here are
some tips on making your voice prompts user-friendly:
•
Short messages are preferable for prompts; most English prompts
can be stated in ½ second. Instead of saying, “Enter the Item
Number,” say “Item”. The typical 802 RF Terminal operator does
not want to hear long messages thousands of times. Error messages
are typically longer because they are the exception and need to
provide more precise instruction to the user.
•
•
Record your voice prompts calmly. A frantic sounding voice can
become irritating, especially when heard repeatedly.
Speak clearly. Correct pronunciation will make the voice prompts
easier to follow for all users. Use common words that all users will
understand.
•
Vary the tone of your voice for different prompts. Using a
different tone of voice or even a different voice for consecutive
7-1
Download from Www.Somanuals.com. All Manuals Search And Download.
prompts or error messages will make it easier for the user to
distinguish between them.
•
Be sure to record error messages for all possible problems that
the user may encounter during a session. Once the operator
becomes accustomed to listening to the voice prompts, it may
become easy to overlook a “display only” error message.
802 RF Terminal’s Voice Message Mapping
The 802 RF Terminal is shipped with 75 seconds of total recording time.
The time allotted for each message is partitioned as follows:
30 – ½ second messages (message numbers 01-30)
30 - 1 second messages (message numbers 31-60)
15 - 2 second messages (message numbers 61-75)
Messages are sequentially numbered beginning with the ½-second
messages, followed by the 1-second messages, and finally the 2-second
messages. You can change the partitions to allow for more or less of a
particular length message. For example, if you decide you do not want any
½ second messages and you want 15 more 1-second messages, your
allocation would look like this:
00 – ½ second message
45 - 1 second messages (message numbers 01-45)
15 - 2 second messages (message numbers 46-60)
Voice message partitions are set in the 802 RF Terminal either from the bar
coded Setup Menu or by the keypad setup. From the Setup Menu, scan the bar
code for “Voice Messages”, and then scan six digits. The first 2 digits
correspond to the ½ second messages, the second 2 digits for the 1-second
messages and the last 2 digits for the 2-second messages. See Chapter 2; RF
System Setup for details on Terminal setup (by bar code setup menu and
keypad). Remember that the total amount of time must add up to 75 seconds.
Programming Voice Messages
To record and playback messages you have to get to SETUP MODE and
enter the password. If you don’t know how to do this, see Chapter 2; RF
System Setup for details on how to get into the SETUP MODE. Once you
have entered the password (password is “WDTRI”) you will see the
following prompt:
R/F Terminal Setup->1
Voice Operations---->2
Press 2 to select Voice Operations. The next screen gives you your options:
7-2
Download from Www.Somanuals.com. All Manuals Search And Download.
Record/Playback--->1
Cloning Master----->3
Cloning Receiver-->4
Pressing the “1” key takes you into the voice recording and playback
function. “3” and “4” allow you to clone voice messages from one 802 RF
Terminal to another. Each option is shown in detail below:
Recording and Playback of Voice Messages
If you respond with a “1” at the menu, you will see the following
Record/Playback prompt:
RECORD/PLAYBACK?
KEY [R/P]?
First, we will playback a message that has already been recorded. Let’s use
message #01 for this example. Press the P key (for Playback) to get to the
next prompt:
KEY [R/P]?
MESSAGE #: _
At this prompt, enter a two digit number for the message number you want
to listen to. Enter “01” and then press the ENTER key. You will probably
hear the “ITEM” prompt recorded at the factory unless you have edited or
reset the default messages. If you heard nothing, a new message can be
safely recorded in the area assigned to message # 01. After you have heard
the message (or static if no message has been recorded), the 802 RF
Terminal displays the RECORD/PLAYBACK prompt again:
RECORD/PLAYBACK?
KEY [R/P]?
To record a message, get out the microphone (no, it’s not an earphone)
shipped with the 802 RF Terminal and plug it into the AUX jack located
next to the POWER jack on the bottom of the 802 RF Terminal. Answer the
prompt by pressing the R key to record a message. The bottom line of the
display now reads:
MESSAGE #: _
Enter the message number you are going to record. For this example, enter
message #03 (by default this is a blank message) by pressing 03, then the
ENTER key. The 802 RF Terminal screen now shows:
HIT ANY KEY TO
START RECORDING
To record a message, press any key and hold it down. When you release the
key, immediately start speaking into the microphone. To practice, let’s
record something in message #03. Get ready to say ITEM (in English or
7-3

your language) into the microphone of the 802 RF Terminal. When ready,
press the ENTER key and the instant you release it, speak ITEM into the
microphone. Remember to speak clearly – you have plenty of time to say
ITEM in ½ second. When the message time is over, you will hear two
beeps. The display is back to the RECORD/PLAYBACK prompt:
RECORD/PLAYBACK?
KEY [R/P]?
Now you’re ready to listen to your first recording. Press the P key and key
in 03 for the message number. Do not be discouraged if you didn’t record
the entire message. Our first attempt produced “EM” in a very frantic tone
of voice. Practice speaking clearly and calmly (think of the poor guy who
has to hear it 10,000 times next week) as soon as the key is released. You
will get the hang of it with just a little practice.
That is the way all messages – prompts and errors - are recorded. If you are
not sure which message numbers are blank, you can listen to messages until
you find a blank for recording.
The host computer relies on the fact that the voice messages are stored in
the 802 RF Terminal itself and not generated by the host. The host
computer will trigger the broadcast of a voice message by sending a prompt
to the 802 RF Terminal that tells it which message number to play. If the
host thinks that message #05 is STOP when it’s really GO, it can cause
confusion for the operator. That is why it is important to keep track of what
messages are recorded where.

Cloning Voice Messages and Setup from 802 RF
Terminal to 802 RF Terminal
If you have several 802 RF Terminals, you can record all of your voice
messages in one 802 RF Terminal and then simply “clone” them to your
other 802 RF Terminals. Cloning also copies the 802 RF Terminal setup
(except for Terminal ID).
7-4
Download from Www.Somanuals.com. All Manuals Search And Download.
You need 2 cables to clone 802 RF Terminals; the Data Cloning Cable
#F38 and the Voice Cloning Cable #T15. The Data Cloning Cable plugs
into the “Computer” port on each 802 RF Terminal. This cable must be
connected to clone properly.
One jack on the Voice Cloning Cable has two black rings on it – this end
must plug in to the RECEIVING 802 RF Terminal (the one you are
transmitting to). Plug the single-banded jack end into the MASTER 802 RF
Terminal (the one you are going to record from).
Once both cables are plugged in to both Terminals, go to the Setup Menu on
both Terminals. Select 3 for Voice Operations from the menu.
The “Receiving” 802 RF Terminal must be started first. On the receiving
Terminal, press the 4 key for Cloning Receiver. The “Receiving” unit will
display:
Recv Setup/Voice
Please Wait_
Now you can start the “Master” 802 RF Terminal by pressing the 3 key for
Cloning Master. The “Master” Terminal will display:
Xmit Setup/Voice
Please Wait_
During the cloning process, you will hear the voice messages played aloud
as they are copied. The process takes about 75 seconds to complete. After
the Terminals are done cloning, they will both display:
End of Cloning
Hit Any Key_
If you did not hear the correct messages or you heard no messages at all,
check your cables and receiver/master setup - you may have transmitted
from the wrong 802 RF Terminal.

Troubleshooting
General Considerations
System Test
If your program fails to run successfully, you can run the 802 Test Program
to check out the host/network/access point/terminal link.
Radio Test
If you are not Signed In, the best way to test the radio is to perform a Site
Survey. If you are already Signed In and operating, you can check the
Signal Strength of the Access Points by pressing the Status Key and reading
the Signal Strength on the last line displayed. Do this test at about 50 feet or
less from the Access point (no walls). If either test reads less than 20%,
chances are that you have a Terminal Device's radio that needs repair.
Changing Batteries
For RF Terminals, the most frequent cause of problems is low batteries that
have either been ignored or undetected. The real test for batteries is to
remove batteries from a working unit and place them in a suspect unit.
Don’t assume that just because the batteries are new they are good. We
have purchased “new “ batteries off the shelf and tested them immediately
to discover they are bad.
Most of the time batteries become the problem as a result of two failures:
1. The operator ignores the Low Batteries message and doesn’t finish
up the transaction and immediately change the batteries. If you turn
the unit off and turn it on again, the batteries may have had time to
“almost” recover. Unfortunately they will have so little reserve
power that they will likely operate just long enough to produce some
very screwy behavior on the RF Terminal. Intermittent laser beams,
continuous beeping, black bars on the screen, etc. are just a few of
the disastrous symptoms that can be exhibited.
2. NiMH rechargeable batteries are being used, but the Terminal thinks
that Alkalines are still being used. The Terminal ships with Alkaline
batteries in the Setup. Alkalines and rechargeable batteries have
different voltage profiles, so the Terminal has to know if you have
decided to use rechargeables in order to properly notify you that the
batteries have reached the low point requiring the batteries to be
changed.
If you are using rechargeable batteries, you must change the Batteries
parameter in the Terminal Setup to reflect the usage of rechargeable
batteries, otherwise you will strange behavior on the Terminal including:

Troubleshooting specific problems
My response time is poor...
•
•
•
•
First, do Site Survey 50 feet from the Access Point. If it's not 40-
50+ the Radio in the Terminal or the Access Point is the problem.
Second, run the 802 Test Program. If it runs fast, your program
that is slow.
If you have good response time everywhere but on the outer fringe
area, you may need to add another Access Point.
If using the Active X program with XP, be sure "connection
pooling" is disabled.
I'm not getting the distance I need...
To maximize range, the Access Points should be located:
1. At the center of the area of intended coverage, and
2. As high as possible - mounted on the ceiling of a room with the
antenna pointing downward works the best. Sometimes just raising
the Access Point to 12 feet will dramatically increase the distance,
especially in warehouses or grocery stores with tall shelving.
Access Points mounted on the wall with the antenna parallel to the
floor is the worst position.
To accurately determine the hardware required to cover a particular
area, you should use Site Survey option on the mode menu.

If the batteries are way low, when turned on, the Terminal will just
keep beeping; it is cycling power, over and over because the batteries
are too low.
If the batteries are at a specific low point, the laser triggering or
playing a voice message will be just enough extra power draw to
force the terminal to cycle power.

Problems reading Bar Codes
The reader won't beep when I try to read bar codes...
•
Try reading a known good bar code - try the 1 on the Setup Menu
bar pad table. Follow the steps for proper scanning technique
discussed in Appendix M; How to scan a bar code.
•
Make sure the reader is configured to read the type of bar code you are
trying to scan. Most bar code types are disabled by default and need
to be enabled using the Setup Menu or keypad while in Setup Mode.
I get extra characters at the beginning or end of my bar code data...
Clear the Preamble and Postamble settings.
•
I have very poor read rates when scanning bar codes...
•
Carefully follow the scanning instructions in Appendix M; How to
scan a bar code when reading any and all bar codes. As
straightforward as scanning may seem, many people who call with a
complaint about poor read rates simply aren't doing it right.
•
Try reading the following bar code below as an example of a
known “good” bar code. This bar code is a Code 39 bar code and is
readable by the RF Terminal set to its default settings.
•
•
Make sure your bar codes have clearly defined dark bars and clean
white spaces. If the bars are so light that they are gray instead of
black or are so dark that they “bleed” into the white spaces, the
printing of the bar codes is the problem. Whoever is printing the
bar codes needs to make the necessary corrections.
The bar code should also have a “quiet zone” of at least ¼” to the
left of the first bar and to the right of the last bar. Make sure to
start your scanning to the left of the bar code in the “quiet zone”,
moving the scanner quickly and smoothly as if drawing a line

through the bar code. If using a laser scanner or CCD scanner,
make sure the beam covers the bar code completely.
•
If using a laser or CCD, clean the window of the scanner with a
soft cloth.
If you have a problem…
•
If you have a problem with your RF System, consult the
troubleshooting section of this manual FIRST. As a last
resort before calling for an RMA, you can perform a diagnostic
reset on your terminal. This resets everything back to the
factory defaults, so be prepared to remake any setup changes
(i.e. Terminal ID) you had made prior to the reset.
1. At the SIGN ON prompt, press the F1 key and release it.
2. then press the SHIFT key and release it.
3. press the D key and release (you will now see a menu)
4. press the K key and release.
If you cannot find the answer here, or the diagnostic reset does
not work, call your Dealer or Worth Data for help.
•
•
Save the shipping box. If you ever need to send the RF
Terminal or any of its’ parts back for repair, us this box.
Before you call your dealer or Worth Data for technical
support, have your RF Terminal and related equipment in front
of you and be prepared to explain your problem in detail to
the Technical Support Engineer.
•
•
The Engineer may ask you to go through some troubleshooting
procedures while on the telephone. This will help them
determine what is wrong and what the course of action should
be. Many problems can be resolved over the telephone and
will not require that you return the equipment to us. If you
do need to return any of the RF equipment to Worth Data, the
Engineer will issue an RMA number.
If you do need to return the RF Terminal for ANY reason, you
MUST have an RMA number first. Write the RMA number
on the outside of the original shipping box and make sure to
insure the shipment. All RMAs should be shipped back to the
following address unless directed otherwise:

Firmware Upgrades
Occasionally it is necessary to get firmware fixes for problems
discovered with the R/F Terminal System.
R/F Terminal Firmware Upgrades
The R/F Terminal firmware can be upgraded by downloading new
firmware into the R/F Terminal from your computer over the radio link
or using the serial port of the RF Terminal connected to your computer
using the 802 Firmware Loader Utility.
You can always get the latest RF Terminal firmware from our website
at the address: http://www.barcodehq.com/download.html
Firmware Download via Radio Link
The RF Terminal's firmware can be updated using the radio link only,
(no need to connect to the serial port of computer and terminal). This
firmware download can take place while other terminals are in normal
operation.
The WD802Term ActiveX component must be running either within
your application program or you can run the 802 Test Program.
The firmware version to which you intend upgrade needs to be in a
folder named "802 Firmware" on the root directory of your "c:" hard
drive. (If you don't have a c: drive, map another drive to it using
Windows Explorer).
At the mode menu which shows:
DEVICE SIGN ON ------>1

Serial Firmware Download for a Terminal
The RF Terminal firmware can also be upgraded by downloading a file
with the current firmware into the RF Terminal's flash EPROM using
the RF Terminal EPROM Loader Windows program found on the 802
Terminal Utilities Disk. However, you will need a Worth Data F36
Serial cable to perform the download.
Download the firmware into the R/F Terminal by following the
instructions on the screens of the program for a normal Terminal
firmware update.
The normal firmware update is done through RF. If there is some bug
in the RF communication there is a failsafe firmware download through
the serial port using an F36 Serial Cable.
Failsafe Firmware Download for a Terminal
If the firmware gets completely wiped out, you will get a blank screen
or a blank screen with a cursor in the upper left. There is a failsafe
download still possible, but you will need to open up the RF Terminal
case and move a jumper to the FDL position as shown below.
After moving the jumper, reassemble the case, plug the power into the
RF Terminal, and connect the F36 Serial Cable to the host computer
and proceed to download firmware using the 802 RF Terminal EPROM
Loader program. Specify a failsafe terminal firmware update and
follow the program's directions.

Appendix C
Code 39 Specifications
Code 39 (or Code 3 of 9) is the de facto standard of non-retail American
industry. It is widely used in the automotive industry (AIAG specifications)
as well as in government and military applications (LOGMARS specifi-
cations). Code 39 is flexible, features a large character set, variable data
length and density, and bi-directional readability. Code 39 is extremely
accurate; substitution errors are almost nonexistent. Its character set
consists of numbers 0 through 9, upper case A-Z, and characters Space, $,
%. / + and -.
The name "Code 39" comes from both the fact that its
character set originally contained 39 characters (it
now has 43) and from its structure. Each character is
formed of three wide and six narrow elements, made
up of five bars and four spaces. Code 39's density can
vary from a low of .75 characters per inch (cpi) to a
high of 9.4 cpi. There should be a ¼" "quiet zone"
*C39*
(white space) to the left and right of the bar code.
Code 39 uses an asterisk (*) as a start and stop character. This character
must precede and follow the data in the bar code. The RF Terminal gives
you the option of transmitting or not transmitting these characters when the
bar code is read.
Exact specifications for Code 39 and other bar code symbologies can be
obtained from ANSI at the address below:

Code 39 Advanced Features and Functions
Mod 43 Check Character
Standard Code 39 can be printed with a "Mod 43 Check Character".
This Mod 43 check character cannot be used with Full ASCII Code

Mod 43 Check character calculation for Code 39
Here is an example to illustrate how the check character is calculated
for bar code data of 123XYZ:
1. Take the sum of the values assigned to each character:
1 + 2 + 3 + 33 + 34 + 35 = 108
1
2
3
X
Y
Z
2. Divide the sum by 43: (thus the name modulus 43)
108/43 = 2 with a Remainder of 22
3. Find the character corresponding with the remainder.
M (value 22) is the CHECK CHARACTER
The data becomes 123XYZM, with M added as the Mod-43 check
character.

Accumulate Mode
Accumulate Mode is an option allowing the RF Terminal to accumulate
multiple bar codes in its buffer, then transmit them to the computer as if
they had been a single bar code. This is useful for entering quantities
and other variable data.
Accumulate Mode works with Code 39, Code 93 and Code 128 only
and can't be used with a check digit. When the RF Terminal reads a bar
code with a space as the first character, it beeps and buffers the data
without transmission. It continues to read and buffer bar codes (up to
40 characters) until it reads a bar code without a leading space. Once
it reads this last bar code, the entire buffer (including that last code) is
transmitted as one long bar code. A “double-minus” sign (--) bar code
clears the buffer. The ENTER code on this Barpad is a Code 39
Start/Stop Character only.
Accumulate Mode must be turned on using the bar coded Setup Menu
or by using the keypad. Accumulate Mode is located in the Code 39
parameters. Choose 4 to Enable or 5 to Disable this feature.
This numeric Code 39 "Barpad" illustrates ACCUMULATE Mode.
Scan 5, 3, 8, and Enter. The RF Terminal transmits a single message of
“538”.

Appendix D
Code 93 Specifications
Code 93 is variable length, continuous, bi-directional, compact code. Code
93 is an alphanumeric bar code which consists of 43 data characters (0-
9,A-Z,$/+%.- and Space), 4 control characters, and a unique start/stop
character. The entire set of 128 ASCII characters is represented in Code 93
using combinations of control characters and data characters.
The control characters are
,
,
, and
. Pairing these control
characters with normal data characters creates full ASCII 93. It is almost
identical to the pairings for Code 39; Code 39 uses $M to produce a
Carriage Return (ASCII 13) character -- Code 93 uses
Carriage Return.
M to produce the
Code 93's two built-in check digits greatly minimize the possibility of
reader substitution errors. The bar code reader never transmits digits the
check digits. Code 93's Start and Stop characters are also never transmitted.
If you have not decided which bar code type to use for your application and
are considering using Code 93, while we agree that Code 93 is an excellent
code, we believe that Code 128 is generally preferable because:
1. Code 93 does not have the numeric compression capability
that 128 does, and
2. Code 93 requires pairings to make all Full ASCII
characters while 128 does not.

Appendix E
Codabar Specifications
Codabar is widely used in libraries, blood banks, the
cotton industry and transportation industries. Its'
character set consists of numbers 0 through 9, and
punctuation characters + . - / : and $. Symbols a, b,
c, d, t, n, * and e are used as start and stop
characters. Characters are constructed of four bars
and three spaces.
a12345b
Codabar is a numeric-only code, but different combinations of start and
stop characters can be used to identify different types of labels.
Codabar's variable data length and extremely low error rate make for a
versatile bar code.
Codabar start/stop transmission
The Codabar section on the RF Terminal Setup Menu lets you
determine whether Codabar start/stop characters are transmitted or not.
If you are varying start/stop characters with different types of labels,
you'll want to "Enable Stop/Start character Transmission".
Start/stop character transmission can also be helpful if you want your
program to differentiate between data coming from the RF Terminal
and data coming from the keyboard. If neither of these situations apply,
you'll probably want to disable it.

Appendix F
Code 128 Specifications
Code 128 is a very powerful bar code, combining an extensive character set
and variable length with compactness and error checking. The character set
contains all 128 ASCII characters with each character made up of three bars
and three spaces. Each element (bar or space) varies from one to four units
in width, totaling 11 units of width per character. Code 128 contains two
levels of error checking:
•
•
Each character is checked for internal parity, and
The last character is a checksum.
Code 128 has three subsets, A, B and C. Subset A
contains alphanumeric characters and unprintable
control characters, subset B contains alphanumeric
characters plus printable control characters and subset
C contains only numeric characters and uses a 2-
character encoding scheme to create a more compact
bar code. Code 128 uses an internal Mod 103 check
12345
character that is not displayed by the bar code reader. Code 128 bar codes
can be made up of only one subset or may be a combination of several.
The Code 39 features of Accumulate Mode, Caps Lock ON and Caps
lock OFF also apply to Code 128.
UCC-128/ EAN-128
UCC-128/EAN-128 Code is a subset of Code 128 adopted by the UCC
and EAN council’s for use as a shipping label symbology. UCC/EAN-
128 bar codes always start with a Function Code 1 character. In
addition, a Function Code 1 character terminates all variable length
fields unless they are the last field in the bar code.
The RF Terminal outputs the following for the special function codes
and start sequences:
]C1
^]
Start C/Function Code 1
(GS) Function Code 1 as a variable string terminator
If UCC/EAN 128 is enabled, the reader looks for the Start C/Function
Code 1 to indicate a UCC/EAN 128 bar code.
The UCC Serial Shipping Container Code specification calls for a
19 digit UCC/EAN 128 code with an additional Mod 10 Check digit
(20 digits in all). The Mod 10 Check digit is calculated the same as the
Interleaved 2 of 5 example in Appendix D. It is the data length as well
as the MOD 10 check digit that distinguishes the UCC Serial Shipping
Container Code from other UCC /EAN 128 bar codes.
F-1
Download from Www.Somanuals.com. All Manuals Search And Download.
Scanning the appropriate bar codes on the RF Terminal Setup Menu
enables UCC/EAN 128; or you can use the keypad in the
PROGRAMMING MODE “Change Setup” option. If UCC/EAN 128
is enabled, you will be able to read both standard Code 128 bar codes
as well as the UCC/EAN 128 bar codes with the Function 1 character
and the Mod 10 check character.
UCC-128 Shipping Container Code
If UCC/EAN-128 is enabled on the R/F Terminal reader, all Function 1
codes are transmitted as ]C1. In addition, should you be reading a 20
digit Shipping Serial Container code, the Mod 10 check digit is also
compared with the computed Mod 10 value to give further assurance of
no substitutions. The UCC/EAN-128 Shipping Serial Container Code is a
subset of UCC-128 or EAN-128 adopted for voluntary marking of
shipping boxes with the exact serial number of the box, (used with EDI
typically to identify a specific boxes contents. The code consists of the
following format:
Start C

The UCC 128 specification is used extensively by the retail industry. If
you have a requirement for a UCC 128 Serial Shipping Container bar
code, be sure to follow the specification as closely as possible as many
vendors will impose fines for non-conformance. For more information

Appendix G
Interleaved 2 of 5 Code
Specifications
Interleaved 2 of 5 Code is a numeric-only, even-number-of-
digits bar code. It is widely used in warehouse and
industrial applications. A combination of five elements, two
wide and three narrow represent each character. Odd-
number position digits are encoded in the bars, even-number
positions in the spaces.
123456
Interleaved 2 of 5 Code is so susceptible to partial scans being
interpreted as valid reads that we recommend at least one of the
following safeguards:
•
Use one length of I 2 of 5 code. Using one length of data
allows you to tell the RF Terminal to look for one length of I 2
of 5 code only. By default, the RF Terminal is set to look for
a 6 digit I 2 of 5 code but you can set the length to something
different using the RF Terminal Setup Menu. Setting the
length to 00 digits allows variable length bar codes scanning.
If you must use the 00 setting, we recommend that you then
use the “Minimum/Maximum” data length field when creating
a program in the RF Terminal to check each field for the
proper length.
•
Use a check digit. Worth Data's LabelRIGHT printing
program automatically calculates and prints a check digit
upon request using the method below:
Interleaved 2 of 5 Mod 10 check digit calculation
1. Assume that the bar code data is 1987.
2. Starting with the least significant digit (in this case, a 7), label
the digits alternatively even and odd.
7 - even
8 - odd
9 - even
1 – odd
3. Take the sum of the odd digits:
8 + 1 = 9
4. Multiply the sum of the even digits by 3:
G-1
Download from Www.Somanuals.com. All Manuals Search And Download.
(7 + 9) x 3 = 48
5. Add the results of steps 3 and 4:
9 + 48 = 57
6. Subtract the result of step 5 from the next highest multiple of 10:
60 - 57 = 3
7. The checksum becomes the low-order digit:
19873
8. Because the data now has an odd length, a leading zero is added,
for the final result of
019873

Appendix H
UPC / EAN Specifications
UPC symbols are found on almost all grocery
products and many other retail items. The
UPC code most people are familiar with
(UPC-A) is a fixed-length (12 digits) numeric
only code, with the first digit controlled by
UPC coding assignments and the last digit a
checksum. UPC-E and UPC-E1 are variations
of the standard UPC-A code. Each digit is constructed of two bars and two
spaces. UPC has very precise standards of code size, structure, and numbers
to be used.
EAN is an international superset of UPC. EAN-
13 has 13 digits, with the first two digits
representing a country code. The final digit is, as
with UPC, a check digit. EAN-8 is a shorter
version on the EAN-13 code containing seven
data digits and ending again with a checksum.
The exact UPC/EAN symbol specifications are available from:
Uniform Code Council, Inc.
7887 Washington Village Drive, Suite 300
Dayton, OH 45459
937-435-3870
Specifications are also available via the internet at:
http://www.uc-council.org
Keep the following guidelines in mind when printing UPC bar codes:
•
•
If you plan to use a "supermarket-type" in-counter scanner
to read the codes, specify a bar code height of at least .9"
for an optimal first read rate.
Make it an early practice to observe the numbering
conventions of the UPC Council. Do not label unmarked
merchandise with a bar code whose numbers may conflict
with those already assigned. If products with these
numbers are not in your store now, they are likely to be in
the future, causing conflicts in your inventory system.

•
The leading Number System Character, (the first number of
the 11 digits to be entered) should conform to these UPC
assignments:
0,6,7,8 Regular UPC 12 digit codes with numbers assignedby
the UPC Council. (Do not use 0 as the leading number
for in-store marking).

Items.
4
5
Use this leading digit for in-store marking of non-food
items.
Reserved for coupons. Do not use this today, or you will
not be able to process coupons through your system
tomorrow.
Supplemental codes
The UPC standards include the addition of a 2
or 5-character supplemental code as well as the
Extended Coupon Code. To read the
supplements, you must first enable them using
the RF Terminal Setup Menu.
NOTE: Enabling the supplements disallows the reading of UPC codes
from right to left to assure that the 2 and 5 digit supplements are not
get missed. Coupon codes can be read from right to left or left to right.
ISBN Specifications
ISBN (International Standard Book Numbering) bar codes are essentially
EAN-13 with a 5 digit supplement, where the first 3 digits are the
Bookland country codes of 978 for books and 977 for periodicals.
Although the bar code contains 18 characters, the ISBN format uses only
9 of them, along with a newly calculated Mod-11 check digit. For
example, a bar code containing the numbers 978055337062153495
would transmit as 0553370626 in the ISBN format.
The RF Terminal has the option of transmitting in the ISBN format.

The UPC/EAN checksum character
The last character in a UPC-A, UPC-E, UPC-E1, EAN-13 or EAN-8
bar code is the checksum. For reference, these are the methods of
calculation:
Checksum calculation for UPC-A, EAN-13 and EAN-8
Use Worth Data's phone number (it's not a real UPC-A code) as sample
data:

odd even odd even odd even odd even odd even odd
1. Starting with the leading digit, 8, take the sum of all the
characters in the odd positions.
8 + 9 +8 + 4 + 3 + 1 = 33
2. Multiply the result of step 1 by 3.
33 x 3 = 99
3. Now take the sum of all the even-position characters.
3 + 9 + 5 + 1 + 8 = 26
4. Add the result in Step 2 to the result in Step 3.
99 + 26 = 125
5. Subtract the result from the next higher multiple of 10.
Next higher multiple of 10 over 125 = 130
130 - 125 = 5
5 is the Modulo-10 check character. The data to be printed
becomes:
183145899385.

MSI/Plessey Specifications
Plessey is a variable length numeric only bar code. MSI Bar Code is a
variable length, numeric-only code with an automatically appended
Modulus 10 check digit. MSI is sometimes called Modified Plessey Code.
If the user specifies an additional check digit, the MSI code can be 14 digits
long, otherwise it has a maximum length of 13 characters. This is how the
MSI check digit(s) are calculated:
The MSI Mod 10 check digit is calculated as follows:
The example bar code data is:
82345
1. Form a number from the odd positions, starting in the units
position.
835
2. Multiply the new number by 2
(835) x 2 = 1670
3. Add the digits of product
1 + 6 + 7 + 0 = 14
4. Add the even digits of the original number to the result in 3
2 + 4 + 14 = 20
5. Subtract the result from the next highest multiple of 10
20 - 20 = 0
6. New Check Digit

1. Assign a checking factor to each number, starting with the
units position of the number (in this example, the 2) up to
the highest order position (the 9). Use checking factors of:
2,3,4,5,6,7,2,3,4,5,6,7...
2. Multiply the checking factor with its assigned number and
add the products:
4 + 12 + 32 + 35 + 30 + 28 + 6 + 12 + 36 = 195
3. Divide the sum by 11
195/11 = 17 remainder 8
4. Subtract remainder from 11
11 - 8 = 3
5. New Check Digit
3
(If the remainder is 10, no check digit is added.)
6. Data with check digit is:

Appendix J
How to scan a bar code
The RF Terminal can be used with either a laser or a CCD scanner. Which
one you choose is dependent upon your application and the quality and
density of your bar codes. This section will include information on
different scanners as well as how to use each one.
Laser and CCD Scanners
If you are using a laser or CCD scanner, technique is not critical. The
scanners are “point-and-shoot”; you can’t miss. Upon triggering the beam,
the laser and CCD scans the bar code multiple times (36 scans per second)
until it has a good read, at which point it automatically shuts off. These
scanners are more expensive, but virtually foolproof. They read from a
distance, so they are much more convenient for distance shelf scanning or
scanning in tight spots. Different laser scanners have different distance
capabilities. Table M-1 shows the comparison of all the laser and CCD
scanners available from Worth Data.

To try scanning a bar code using your laser or CCD scanner, (whether
it be a handheld or integrated)
1. Have your 802 RF Terminal either at the opening screen or at the
Mode Menu.
2. point the laser scanner at the bar code at about 6” away.
3. Pull the trigger (or push the button on an integrated model)
and line up the beam on the bar code. If you don’t get a read,
vary the distance of the scanner from the bar code by pulling
up or moving down. The idea is to scan through the center of
the bar code.

Laser Options
Several options are applicable to all laser and CCD Scanners that are
used with the RF Terminal. These options are: 1) Longer timeout on
the laser reading, and 2) Double decode required.
Longer Laser Reading: A temporary solution to problem bar codes is
sometimes to increase the length of the time the scanner attempts to read,
from the default 2-second beam to a 4-second beam. To select the 4-
second beam:
Scan Start Setup
Scan Laser Options
Scan 3 to select the 4-second beam
Scan End Setup
To return to the default 2-second beam, scan 2.
Double Decode: The default setting for the RF Terminal is one
successful decode results in a “good read”. If you are getting incorrect
reads, (due to defective bar codes), a temporary solution is to turn on
make the RF Terminal perform two straight identical decodes before
beeping, outputting data, and completing a “good read” read.
To activate the double decode:
Scan Start Setup
Scan Laser Options
Scan 1 to select double decode
Scan End Setup
To return to the single decode beam, scan 0.
There are two Setup Options that do not apply to the LZ300. The two
options are:
1. “Aiming Laser Dot” for a predetermined time before the laser
beam expands into a “line” for reading. The RF terminal
requires a no charge feature to be added to it before shipping
for the Aiming Dot to be used. This feature applies to the
LT70x models of the RF Terminal with its built-in laser and
the external tethered LZ400 Laser Scanner.
2. “Difficult Code 39 Reading” for reading Vehicle
Identification Numbers (VIN) through the automobile
windshield. This applies only to the external tethered LZ400
Laser Scanner.
Aiming the Laser Dot:
Sometimes it is difficult to see the laser beam and know you are on the
bar code, especially if you are attempting to read outdoors in direct
J-2

sunlight. The laser can be outputted as a brighter dot for a few seconds,
allowing the user to place the dot in the middle of the bar code; then the
laser beam starts sweeping for the read. As shipped, the laser beam
never forms an aiming dot, but you can program a number of seconds
that you wish the aiming dot to appear before the sweeping beam by
scanning the following:
From the Keypad, go to RF Terminal Setup. Choose “Other”. Press
Enter repeatedly until you get to the parameter labeled “AIMING
DOT”. The default is 00. Enter the time in 1/10s of a second you wish
the dot to appear before the laser beam spreads, (i.e. enter 30 for 3
seconds).
"Difficult Code 39 Reading":
This setting facilitates reading of difficult Code 39 bar codes such as
the Vehicle Identification Number (VIN number) on automobiles,
especially reading through a windshield. VIN numbers are long, often
weathered, often dirty, and challenging to read.
To enable the more aggressive Code 39 algorithms necessary to read
windshield VINs with a LZ400:
Scan Start Setup
Scan 2 of 5 Code
Scan D for windshield reading
Scan End Setup
To return to the default Code 39 decode algorithms, scan B instead
of D.
Don’ forget the common sense things you can do to facilitate reading
the VIN:
1. Be sure the window on the laser scanner is clean.
2. Be sure the windshield itself is wiped clean before
reading

Appendix K
Using the Scan Stand
Stand mode allows the operator to use an LZ300 laser in “hands free” mode
while attached to an RF Terminal. This is useful in shipping applications or any
application where the operator requires both hands to perform their function.
Stand Mode is actually a fast cycling laser looking for a bar code (many
transitions between black and white). The user scans the bar code on the
Stand to activate it. A scan of the same bar code while in "Stand Mode" will
deactivate it. The "Stand Mode" on the RF Terminal only supports the
external LZ300 Scanner, not the internal scanner and not the LZ400
Scanner. When the scanner detects a suspect bar code, the beam spreads
wider and stays on for 2 1/2 second or until a bar code is successfully read.
If successfully read, the scanner turns off until the next prompt. If no read
occurred, it resumes the cycling looking for a prospective bar code.
When in Stand Mode, if a key is pressed, we assume the user wants to key
data instead of scan data, so the scanner is turned off; at this point the
scanner can be used if triggered. Once the data entry is finished and
transmitted and the next prompt is received from the host program
requesting either 1) scanner only input, or 2) scanner/keyboard input; the
"Stand Mode" operation is resumed.
The Stand itself is available in two models, one with a weighted base (if you
need to move the stand from site to site) or a gooseneck-only model that
must be permanently mounted to a surface.

It acts just like a laser scanner, except the beam is fuzzier than the
lasers sharp line across the bar code. The cable (rated for 1,000,000
bends). The warranty is 2 years.
Laser Scanners
The LT802 model RF Terminal is available with an integrated laser
scanner for one-handed scanning. This laser uses the Symbol SE900
Scan Engine with a lifetime warranty on the scan element. We also offer
cabled laser scanners (the LZ300, LZ400 and PSC Long Range) as an
add-on, plugging directly into the SCANNER port of the RF Terminal.

LZ400 Laser Scanner
This laser scanner is the equivalent of the lasers used in the LT802. The
LZ400 uses the Symbol 1200HP Scan Engine with a lifetime warranty
on the scan element. It can read a 10 mil bar code at 17", a 40 mil bar
code at 44 “ ft., and a reflective 100 mil bar code at 9.5 ft. It can read
high density code down to a 3 mil narrow bar width.
This scanner supports the aiming dot mode, useful for difficult aiming
and scanning in bright sunlight.
Durability features include a cable tested to withstand 1,000,000 bends
of operation, as well as a scan engine tested to withstand 2000 G's of
force. It is an extremely rugged product, made to withstand harsh
treatment including repeated drops.
PSC Long Range Laser
This laser is a long-range laser (it reads a 100 mil reflective bar code
from up to 17 ft.), but it also reads normal codes. This makes it ideal for
reading shelves so high you can’t even reach them, (i.e. a forklift
operator can scan the shelves without getting up); but it can still read
desktop bar codes at close range. It actually has two lasers built-in; one
for close up reading, and one for distance reading. It has a two position
trigger; the first position stop is an aiming spot, the second position stop
triggers the beam. Warranty is 2 year.
Laser Accessories
H11 Laser Holder
The H11 Laser Holder is for the LZ300 and LZ400 laser scanners. The
H11 Laser Holder can be mounted vertically (wall) or horizontally
(table top). Double-sided tape is included to use for mounting, or you
can use wood or metal screws (not provided) to mount the holder.
