Introduction

The Worth Data RF Laser has the following features:

1) The LZ400-RF Laser Scanner for the USA and Canada. This laser has

a range of up to 500 feet (open area) and has collision detect and retry

logic built within. The LZ400-RF Laser communicates with the B78

Base Station. The Base Station communicates with a host PC through the

USB port or a RS-232 Serial Port. Up to ten LZ-400 RF Lasers can

communicate with one B78 Base Station.

2) If you use the USB interface, data is transmitted as keyboard data. If you

use the serial interface instead, serial data is transmitted to one of the

computer's COM ports.

3) The USA LZ400-RF Laser and Base operate in the 902MHz band. The

laser and base radios operate by "frequency hopping" spread spectrum.

The radios hop from one frequency to another every 400ms. The radio

goes through 25 different frequencies and then repeats the sequence – all

in the 902 MHz band at 15 milliwatts (10 dBm) of power. Different

sequences define the channels. It is possible to have up to ten RF

Lasers/Base Stations in the same area, providing each pair is on separate

channels to avoid interference and general confusion. The RF Laser can

also operate in the same room as the 701 RF Terminal.

4) The R/F Laser can read and discriminate between Code 39, Full ASCII

Code 39, Interleaved 2 of 5, Codabar, Code 128, EAN-13, EAN-8, UPC-

E, UPC-E1, UPC-A, MSI, LabelCode4, LabelCode5, Code 93 and

Plessey.

5) The RF Laser has a rechargeable lithium ion battery. The battery is

recharged with the included F10 5v power supply. Recharge time on

fully discharged batteries is 3 hours. Do NOT use any other power

supply to charge your laser.

Installation

Components of RF Laser Readers

In the event the shipping box shows damage on arrival, please note the

damage on the carrier's receipt log.

The supposed contents of your Reader shipment is the following:

1. An B78 RF Base Station with 1-10 LZ400-RF Lasers.

2. A Worth Data regulated 5V power supply with each LZ400-RF Laser

Scanner ordered, and if you ordered a serial cable with the B78 Base

Station, you will receive a power supply for the Base also. TO

PREVENT DAMAGING the Base Station or RF Laser, DON'T USE

ANY OTHER BRAND OF POWER SUPPLIES.

3. Either a serial cable (F36) or USB cable (C21), depending on which one

you ordered.

4. A plastic barpad for entering variable quantity information and

performing the Link Test without data transmission.

Scanner Beeps and LEDs (what they mean)

When you scan, you will get one beep when you get a successful decode and a

high-pitched beep. The data is then transmitted to the Base Station (as it is

being transmitted, the LED flashes yellow). When the Laser receives the

acknowledgement from the Base Station that the data has been received, the

Laser emits a lower pitched beep and turns on a green LED for three seconds.

If the transmitted data fails to be acknowledged,

1) further scanning is prohibited. You can't pull the trigger again

until the data reaches the base or until you clear the scanner.

2) The laser will retransmit three times, (the yellow LED will

indicate retransmissions).

3) If it fails three times, it will emit a distinct 8 beep pattern and

turn off. This is your clue to check out the Base Station.

4) You can pull the trigger to try transmission again. (the laser beam

will not come on until the transmission is acknowledged or you

hold the trigger down for 30 seconds to clear the data).

USB Installation

USB attachment does not require the Worth Data F10 5v power supply for the

B78 Base Station. If for some reason your USB port or hub does not have

enough power to operate the Base Station correctly, you may use our F10

power supply, but you must plug it in AFTER you have powered up on the

USB cable only. The Base Station will power up with 3 more flashes than the

channel setting; i.e. if it is set on Channel 0, it will flash green three times. If

the Channel were set to 7, it would flash green 10 times.

Once you connect the B78 Base Station to the computer using the supplied

USB cable, the Base Station should be sensed automatically by the computer

and the driver installation will begin. Windows can usually find the necessary

driver on the hard drive under /Windows/System 32/Drivers; occasionally you

will have to insert the original Windows CD. The Mac always finds the driver.

In either case, the driver used is the standard keyboard driver. No special

drivers are required.

You should be connected as below:

If you mistakenly abort your driver installation, see the Trouble Shooting

Section of this manual.

For testing, bring up Notepad or WordPad on your computer and scan the

TEST LABEL on page 21. Now turn to page 7.

Installing the R/F Reader with a dedicated serial port

The Base Station can be directly attached to a spare serial port as shown

below. This configuration requires the Worth Data F10 5v power supply for

powering the Base Station. Upon power-up, the Base Station LED will flash

with 3 more flashes than the channel setting; i.e. if it is set on Channel 0, it

will flash green three times. If the Channel were set to 7, it would flash green

10 times.

Your software will need to read the serial port as a separate device, unless

you're using an IBM-compatible computer and Worth Data’s PortKey

software, which makes serial-port data appear as though it had been typed at

the keyboard. You can also use the WDR Test Utility to test communication

with your com port.

If you specified a 25-pin null-modem cable (part number F34) or a 9-pin cable

(part number F36) when you placed your order, you can cable directly from

the RF/Reader's Y-Cable port to your computer's serial port. Refer to page 6

for the details of the pin-outs of the cables.

Turn to page 7 to configure the RF Laser Reader using the Setup Menu.

Installing the R/F Reader between a computer and

terminal

If you attach the s Base between your computer and a terminal, as shown

below, using Cable Selection F45-1, bar code data will be sent to the computer

as if it had been typed on that terminal. Refer to page 8 for the details of the

pin-outs for each connector on the cable. You will also need to change jumpers

(JP2 on the RF Base) on the board inside the case from the “S” position to the

“Y” position.

This configuration requires the Worth Data F10 5v power supply for powering

the Base Station. Upon power-up, the Base Station LED will flash with 3 more

flashes than the channel setting; i.e. if it is set on Channel 0, it will flash green

three times. If the Channel were set to 7, it would flash green 10 times.

Cables may require modification, depending on the genders and pin-outs of

your serial ports and cables. You may require "gender changers" (available at

most computer stores) for the two 25-pin connectors. Refer to page 6 for the

details of the pin-outs of the dual port serial cable.

Turn to page 7 to configure the reader using the RF Laser Reader Setup

Menu.

Configuring the RF Laser Reader

for your computer and application

The RF Laser Setup Menu is located in Appendix J of

this manual. This simple menu lets you easily configure

the RF Laser to work with almost any computer system,

and to tailor its bar code reading and data format

characteristics.

Be sure to read the scanning instructions on the next

page. To read Reader Setup Menu bar codes and

configure your reader, you must know the right way to

scan bar codes.

These are the RF Laser Reader's default settings and are shipped configured to

these settings; they can be reset to them at any time by scanning the Start

Setup and Reset codes on the RF Laser Setup Menu.

Laser Scanning Instructions

Using a laser scanner is basically as simple and intuitive as "point and shoot"

at a distance of 0-24", depending on the density of the bar code.

Basically, the laser scanner's beam must cross every bar and space on the bar

code, without touching any other bar codes, as shown in the first example

below. You'll need to hold the scanner further away to produce a wider beam

for large bar codes, and closer for bar codes with bars very close together.

Even though momentary exposure to a laser's low-power, visible-light is not

known to be harmful, you should not aim the beam into anyone's eyes.

When you scan, you will get one beep when you get a successful decode and a

high-pitched beep. The data is then transmitted to the Base Station (as it is

being transmitted, the LED flashes yellow). When the Laser receives the

acknowledgement from the Base Station that the data has been received, the

Laser emits a lower pitched beep and turns on a green LED for three seconds.

If the transmitted data fails to be acknowledged,

1) further scanning is prohibited. You can't pull the trigger again

until the data reaches the base or until you clear the scanner.

2) The laser will retransmit three times, (the yellow LED will

indicate retransmissions).

3) If it fails three times, it will emit a distinct 8-beep pattern and

turn off. This is your clue to check out the Base Station.

4) You can pull the trigger to try transmission again. (the laser beam

will not come on until the transmission is acknowledged or you

hold the trigger down for 30 seconds to clear the data).

The important thing to remember about using a laser with the RF Laser Reader

Setup Menu is that you need to make sure the scanner's beam covers only one

bar code at a time. The laser scanner's beam is wide enough, and the

configuration bar codes close together enough, that you will need to use your

fingers, post-it notes, or the supplied Laser Setup Assist window, to "block

off" bar codes adjacent to whatever configuration bar code you need to read.

Download from Www.Somanuals.com. All Manuals Search And Download.

For example, to

read this "5" bar

code on the Setup

Menu, you would

need to cover any

adjacent bar codes

with paper or a

finger first, as

shown.

Don't forget to take the R/F Laser Scanner of Setup Mode by scanning End

Setup, otherwise the batteries will run down totally because the radio

transmitter remains on.

Using The RF Laser Setup Menu

1. To configure your reader using the Reader Setup Menu found in Appendix J

of this manual. You must first scan the Start Setup code at the top left corner.

Do this now. You'll hear two beeps. During Setup, nothing will be

transmitted to your computer; the RF Laser Setup Menu codes are strictly for

configuring the reader. If you did not hear two beeps, try scanning the code

again, until you hear the two beeps. If you've never scanned bar codes before,

read the scanning instructions on page 8 before continuing.

2. Next, choose the parameter you want to change an option for, and scan its

code (i.e. Code 3 of 9, or Postamble). You should hear two beeps if you

scanned correctly.

3. Then, choose the option you want to change from the list below the

parameter bar code you just scanned, and scan the number on the barpad

that corresponds to that option. For example, if you scanned the parameter

“Codabar” and wanted to “Enable Codabar”, you would scan the number

0 on the barpad.

4. Now scan End Setup (at the top-right corner of the Reader Setup Menu to

complete the setup exercise. If you scanned correctly, you'll hear three beeps.

Continue scanning topics and options until you've made all the changes you

desire, and then scan End Setup to complete setup. If you are planning to use

several RF Laser scanners with one base station, pay attention to the Set ID

parameter.

The next several pages will show you all of the various RF Laser options.

Default settings are shown in bold in this manual and marked with an * on the

RF Laser Setup Menu.

RF Laser Setup Parameters

Channel

Default Channel

•

The default Channel is always shipped as 0. There are 10 channels

in the USA and Canada. The Channel for the RF Laser Reader is set

by scanning the Setup Menu.

All Lasers and associated Base Station must be set to the same

channel. If you have more than one RF Laser per Base Station, you

must set a unique ID in each RF Laser. (See SET ID.)

The Laser channel must match the channel on the Base station. See

Appendix A for information on changing the channel on the Base

from the shipped default channel of 0.

For information about Code 39 and Full ASCII Code 39, see Appendix C.

See page 23 for information about Accumulate Mode (this setting also

controls Code 93 and Code 128).

Enabling Start/Stop character transmission means that the RF Laser Reader

will transmit the * Start/Stop characters to your computer along with the data.

For example, data of 1234 would be transmitted as *1234*.

Enabling the Mod 43 Check Digit requires the units position of your data to

match the calculation for the check digit explained in Appendix C.

Download from Www.Somanuals.com. All Manuals Search And Download.

If you've enabled the check digit, enabling Check Digit transmission causes

the reader to transmit it to your computer along with the bar code data.

"Caps Lock ON" means that for all codes lower case letters read as data will be

transmitted as upper case, and upper case as lower. Numbers, punctuation &

control characters are not affected. This applies to Code 128 and Code 93 also.

"Caps Lock OFF" means that letters will be transmitted exactly as read.

EAN-8 is forced to transmit 8 digits

For more information on UPC and EAN, see following page and Appendix H.

Enabling supplements allows you to read 2 and 5-digit supplemental codes

used with magazines and paperbacks. This disallows right-to-left reading of

UPC codes, to assure that the supplement doesn't get skipped.

Use setting 2 to enable reading of the 2 and 5 digit UPC/EAN supplements

commonly found on magazines and paperback books. Use this setting to force left

to right reading of UPC codes, assuring that the supplement code is not missed.

This setting also allows for reading of the UCC/EAN 128 Extended Coupon Code.

The Extended Coupon Code consists of a UPC code with a NSC of 5 or and EAN

code with a country code of 99 along with a Code 128 supplemental code to the

right. This setting allows you to read the Code 128 supplement with the

UPC/EAN, providing the UPC has a NSC of 5 or the EAN code has a country

code of 99. Without the correct NSC or country code, the Code 128 portion will be

ignored; UPC code with an NSC of 5 or EAN codes with country code of 99 will

not be read unless there is a readable Code 128 supplemental code read also.

UPC-E Compressed Format transmits UPC-E codes as is; Expanded

Format adds zeros to make them the same length as UPC-A.

Download from Www.Somanuals.com. All Manuals Search And Download.

UPC-E can be used in either normal UPC-E format (implicit NSC of 0) or

UPC-E1 format (NSC of 1). UPC-E1 is enabled by scanning 2 of 5 Code and

8 (9 disables UPC-E1). It is very easy to partially read EAN-13 as UPC-E1, so

don't enable UPC-E1 if reading EAN-13.

If you wish to transmit UPC-A data in EAN-13 format, (an added leading 0

for the USA's country code), scan Terminator Character and F. Scanning E,

the default, sets UPC back to no country code transmitted.

ISBN, International Standard Book Numbering, bar codes are EAN-13 codes

with a 5 digit supplement. If the first three digits are the "Bookland" country

codes of 978 for books or 977 for periodicals, then you can enable trans-

mission of EAN-13 bar codes in the ISBN format. Suppose you scan an EAN-

13 with 5-digit supplement which is a bar code of 978055337062153495. It

would be transmitted in ISBN format as 0553370626 (as of Jan.1, 2006, the

correct ISBN format is the EAN-13 bar code with the 5 digit supplement).

055337062 are the first nine digits of the ISBN format, and 6 is the newly

calculated Mod-11 check digit.

To enable the transmission of the ISBN format, scan Terminator

Character and D. Scanning C, the default, disables conversion to ISBN

format back to regular EAN-13 format.

check digit, enabling Check Digit transmission causes the reader to transmit it

to your computer along with the bar code data.

2 of 5 Data Length

2 of 5 Code is so susceptible to interpreting partial scans as valid reads

that the RF Laser uses fixed-length data as a safeguard. To choose a data

length, scan it as a two-digit number using the Barpad Table. For example, to

select 8-digit data length, you would scan a 0 and then an 8. Because

Interleaved 2 of 5 is required to be an even number of digits in length, you

must use an even number. If you're unsure of your bar code length,

temporarily set the length to 00, read a bar code, and count its digits and then

set it to the actual length. DO NOT PERMANENTLY SET THE 2 of 5

LENGTH TO 00 or you will get misreads!

Terminator characters (This applies to the BASE only)

CR (Enter)

Tab

None

Depending on your application, you may wish your RF Laser to transmit bar

code data to your computer with an Enter (carriage return), a Tab at the end,

or with no extra terminating character at all.

If you need a terminator character other than CR or TAB, you can get it by

specifying None here and then selecting your desired terminator character(s)

specified in the Postamble (See Page 15).

Beep Options

Decode and Acknowledge

Acknowledge Only

Preamble

A "Preamble" is a user-specified data string transmitted at the beginning of

each bar code. For example, if you specify the preamble @@ and read data of

123456, "@@123456" would be transmitted to your computer.

Download from Www.Somanuals.com. All Manuals Search And Download.

The default is no preamble. To select a preamble, scan up to 15 characters from

the "FULL ASCII MENU" on the back of the RF Laser Setup Menu, and then

scan SET when you're done. To return to the no preamble setting, scan Clear

here instead of scanning SET or any characters from the FULL ASCII MENU.

You can trim 1-15 leading characters from bar code codes by scanning a ~

(tilde -- ASCII 126) followed by a single digit, 1 through F, as part of the

Preamble. (Bar codes that are shorter than the amount-to-trim are transmitted

with no trimming.) Consider the examples in the following table to

understand how trimming works:

Bar Code Data

123

12345678

12345

Preamble

XYZ

~3XYZ

Data Transmitted

XYZ123

XYZ45678

12345678

12345

123456

You can also trim selectively by bar code type. For example, you can trim 2

characters from Code 39 and a different amount from other bar code outputs. This

is done by using the bar code ID character in conjunction with the tilde (~). A

preamble of ~b2~c1 says trim 2 characters from the front of Code 39 output and

trim 1 character from the front of UPC-A. Refer to the Code 128 parameter on

page 12 for a list of the ID character associated with each bar code type.

A final use of the Preamble/Postamble is to enter a minimum/maximum length

check for bar code data read. Use the Preamble or Postamble by entering

|nnmm where "|" is ASCII 124, "nn" is the two digit minimum to be read and

"mm" is the two digit maximum to be read.

Postamble

"Postamble" refers to a user-specified data string transmitted at the end of each

bar code. For instance, if you specify the postamble @@ and read data of

123456, "123456@@" would be transmitted to your computer.

The default is no postamble. To select a postamble, scan up to 15 characters

from the "FULL ASCII MENU" on the back of the Reader Setup Menu, and

then scan SET when you're done. To return to the no postamble setting, scan

CLEAR here instead of scanning SET or any characters from the FULL

ASCII MENU.

You can trim 1-15 trailing characters from bar code codes by scanning a ~ (tilde

-- ASCII 126) followed by a single hex digit, 1 through F. (Bar codes which are

shorter than the amount-to-trim are transmitted without trimming.) Consider the

examples in the following table to understand the options of the Postamble:

Bar codes that are shorter than the sum of the Postamble trimming and

Preamble trimming will be transmitted without trimming. Selective trimming

and min/max bar code data is also supported through Postamble specifications,

(See Preamble above for complete details).

Characters

This setup option allows you to output ASCII characters different from the

ones scanned.

For example: Suppose you want the RF Laser to output a hex 92 character

every time you scan a 1 (hex 31); you want to remap hex 31 to hex 92, (If

you're using 8 data bits, output of 80-F8 codes is possible.)

1) Scan the Start Setup Bar Code

2) Scan the Characters Bar Code on the Setup Sheet.

3) Scan 3 1 and 9 2 to output hex 92 when reading a "1".

4) Scan up to 7 other pairs of character reassignments.

5) Scan Set when complete.

6) Scan End Setup to exit setup mode.

Hex values for each character code are shown on the Full ASCII Menu. The

equivalent decimal values are also shown for each character.

You can also eliminate characters by reassigning hex codes to FF. For

example, to strip all $ (dollar sign) characters from transmission, you would

follow the above instructions and scan 2 4 F F in step 3.

Set ID Character

The ID is used to differentiate between multiple RF Lasers attached to the

same Base Station.

Multiple scanners on one base station require each scanner to be set to a

unique ID of 0,1,2,3.....9. Scan Set ID Character and then scan 0-9 for each

scanner, giving each a different ID of 0-9.

Link Test Code

This is a code to test the transmission link between the RF Laser and its Base

Station, without transmitting data. You can use this to be sure you are in range

and able to hear the base station beeping. No data is transmitted. Do not enter

the Setup Mode when performing the link test. This code is the same as the

"Clear Buffer" code on the Barpad Menu.

Reset

Once you are in the Setup Mode, don't scan Reset unless you're sure you want

to restore the RF Laser to its default settings (as described on page 7), erasing

all changes you've made.

DIFFICULT CODE SETUP OPTIONS

Aiming 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 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:

Scan Start Setup

Scan Aiming Dot Duration

Scan 1 digit from the Barpad Table. The default is 0, for no aiming

dot. You can enter any 1 digit number from 0 to 9 (9 gives you 9

seconds). Typically you will want to set it to a 1 second (scan 1) or a

2 second (scan 2) aiming dot.

Scan End Setup

4-second beam: Another option with problem reading conditions is 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 2 of 5

Scan F to select the 4-second beam

Scan End Setup

To return to the default 2-second beam, scan E instead of F.

Automobile VIN READING:

There is special support for reading automobile Vehicle Identification Numbers,

VIN, remotely from the computer. You may want to use the aiming dot above too.

"Delayed Transmission": is a feature which allows the user to leave the

computer, (perhaps being operated by someone else), go to the location of the

car, scan the VIN with the first trigger pull, return to the computer, be certain

that the screen and cursor are properly positioned, and then pull the trigger

again for transmission. The first trigger pull scans and stores the bar code. The

second trigger pull transmits the data, permitting the user to be sure the cursor

is properly positioned. To change the reader to “Delayed Transmission”:

Scan Start Setup

Scan Terminator

Scan B to select "delayed transmission"

Scan End Setup

To disable "delayed transmission", repeat the above substituting A for B.

"Difficult Code 39 Reading": This feature facilitates reading of he VIN

number on automobiles, which is often a difficult-to-read bar code, 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:

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.

"Double-scan checking": When reading a VIN, you will also want to disable

double scan checking. The reader’s default is to not output or beep until it has

two successive identical decodes. This is an acceptable safeguard with most

codes, but with VIN numbers read through a windshield, you will have to

deactivate double scan checking to get timely reads.

Scan Start Setup

Scan Code 39

Scan F to disable doubles scans.

Scan End Setup

To enable double scan checking, scan E instead of F.

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 is wiped before of reading.

RF Base Station Parameters

The following parameters apply only to a base station attached serially.

Baud rate

300

600

1200

2400

4800

9600

19,200

Data bits

7 Bits

8 Bits

Set the data bits ("word length") to the same setting your terminal is using, or

you want to use with your serial port.

Parity

None

Even

Odd

Set parity to the same setting your terminal is using, or the one you want to use

with your serial port. None is usually used in conjunction with 8 data bits,

Even or Odd with seven data bits.

Stop bits

1 Bit

2 Bits

Set the stop bits to the same setting your terminal is using, or you want to use

with your serial port.

Protocol

This parameter only applies to serial operation of a Base Station.

None

Host Controlled Acknowledge

"None" means that Base Station will immediately transmit an acknowledgement to

the RF Laser from which it has just received transmitted data, (without waiting for

a response from the host computer program.)

Download from Www.Somanuals.com. All Manuals Search And Download.

If you want the host computer program to analyze the data and to send back

different beep patterns to the laser scanner, enable Host Controlled

Acknowledge. With this parameter enabled, the data is passed to the computer

and no acknowledgement is sent to the scanner until the host computer replies to

the base station with one of three possible ASCII codes: ACK (ASCII 06), BEL

(ASCII 07), DC2 (ASCII 18). Upon receipt of these codes from the host

computer, the base sends a signal back to the transmitting laser scanner that

causes it to emit beeps as follows:

ACK - one short beep in laser

BEL - two longer low pitched beeps

DC2 - three longer low pitched beeps

This allows the host computer program to give limited feedback to the scanner

operator.

Test the RF Laser with your computer

If you are connected by USB interface, or if you have a serial reader and are

using PortKey on a PC, you should be able to scan the bar code on the next

page, hear a beep and see data displayed on the computer's screen. First get

your computer to some program where you can type and see it on the screen,

(i.e. Notepad). Now scan the TEST LABEL below. Your screen should show:

TEST LABEL

If you can't read the TEST LABEL, see the Scanning Techniques back on page

8. If you don't get a beep, try moving closer to the Base Station and moving

the scanner closer or farther away from the bar code. If you get a beep but no

data displayed:

•

Check your connections

If you are connected to serial port and aren't using PortKey, you will

need to use a communications program; or use the WDR Serial Test

Program distributed with your serial reader. The program is for

Windows only.

If you are using the WDR Serial Test Program, follow these guidelines:

•

Make sure the serial parameters on your Base Station match those

used by your computer.

Make sure you are connected to a valid serial port.

If you still are having problems, see the Troubleshooting Section.

Radio Considerations

Operating Instructions

Operational Details

The RF Laser:

1. chirps on a "good read" or successful scan while turning off the scanner

beam, and

2. beeps loudly when it gets the acknowledgement back from the Base

Station that it has received the data.

The yellow light on the back of the scanner indicates that it is transmitting.

You will see up to four transmission attempts before the unit goes to sleep and

waits for you to pull the trigger again. The green light indicates that it has

received the acknowledgement from the Base Station. After four unsuccessful

tries of transmitting to the base without an acknowledgement, the scanner

chirps 8 times and goes to sleep waiting on the operator to move closer to the

base station and pull the trigger again for a transmission retry. After going to

sleep on an unsuccessful read, when the trigger is pulled again, the scanner

beam doesn't turn on for reading; instead, the unit beeps three times to indicate

is re-transmitting and just transmits again. This sleep and retransmission cycle

is repeated until the acknowledgement is received or the buffer is deliberately

cleared. In this way, no scanned data is lost, even though you have wandered

out of range of the Base Station. Until the pending data acknowledgment has

been received, pulling the trigger will only retransmit and not activate the

scanning laser beam for additional reading.

If you are out of range and want to clear data in the scanner's buffer waiting to

be transmitted again, by pulling the trigger and holding it down for 30 seconds,

the buffer will be cleared and the scanner will emit 3 low pitched beeps.

Range

The operational range of 500 feet is far greater than is practical to operate

blind from the PC. However, unless the unit becomes defective, you should

experience excellent transmissions in almost any environment.

Avoid locating the Base Station next to a 900 MHz phone. Raise the Base if

you are having any range issues.

Accumulate Mode

Accumulate Mode is an option (which can be enabled or disabled using the RF

Laser Reader Setup Menu's Code 39 section) allowing the reader 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. A small laminated barpad card is provided with each

reader ordered to aid in entering variable quantities.

It works with Code 39 only, and can't be used with a check digit. When the

reader reads a bar code with a leading space, 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. Then the entire

buffer (including that last code) is transmitted as one long bar code. A bar

code of a double minus (--) sign clears the buffer. Scanning a backspace code

($H) backspaces in Full ASCII mode. A handy code for Enter (as seen on the

"Barpad" below) is a Start/Stop only. (No data.) The code to use for testing the

transmission link between the RF Laser Scanner and the RF Base Station is the

CLEAR BUFFER code (the same bar code as titled Link Test on the Setup

Menu. It will cause beeps to be heard, but no data will be transmitted to the

computer -- testing blind with no computer consequence.

This numeric "Barpad" illustrates Accumulate Mode. Scan 5, 3, 8, and Enter.

The reader transmits a single message of 538.

Function/Control Key Support

The RF Laser can also transmit key sequences for function, control, alt

(command and option keys on Macs), cursor and shift keys, for ease of use

with the many software packages using these keys for menus or commands.

You can include these codes in other bar codes, or you can scan these

“keystrokes” into your Preamble or Postamble in order to add them to every

scan from your reader. You must have Full ASCII Code 39 enabled on your

reader (this is the default setting). Scan the corresponding bar code (or pairs of

codes for Pg Up, Pg Dn, Home, etc) from the Full ASCII menu to emulate the

chosen key.

To emulate any of the keys above, scan the appropriate bar code from the

FULL ASCII MENU. For example, to emulate the f5 key, scan the ENQ bar

code.

Download from Www.Somanuals.com. All Manuals Search And Download.

Simply scan the correct bar code(s) from the FULL ASCII MENU. For

example, if the WDP reads the bar code SOH (ASCII 001 -- a control-A) from

the FULL ASCII MENU, it will transmit an F1 key.

Shift, Ctrl and Alt keys require three sequences:

1) The ON code generated when the Shift, Ctrl or Alt key is pressed.

2) The other key to be used in conjunction with the Shift, Ctrl or Alt key.

3) OFF code generated when the Shift, Ctrl or Alt key is released.

(For example, to create a Control C bar code: use Control ON, C, and Control

OFF. To put Control C in a Preamble or Postamble, scan from the Full ASCII

Menu: Control ON, C, and Control OFF).

Function keys F11 and F12

Function keys F11 and F12 require two bar codes to be scanned to make these

functions keys. The F11 key is created by combining the Null and SOH. The

F12 key is created by combining the Null and the STX.

Windows Key

The Windows key on a Windows keyboard is transmitted by scanning 4 bar

codes - NULL and C for Windows On (pressing down) and NULL and D for

Windows Off (releasing the key).

Command and Option Keys on Mac USB Keyboards

When you have a WDP Reader attached to a Macintosh Computer's USB port,

to emulate the Command key, use the Windows key ON/OFF bar codes

NULL, C (Command ON) and NULL, D (Command OFF) For the Option Key

ON/OFF use RS (Option On) and US (Option Off).

Transmitting any ASCII character using its 3-digit ASCII code

You can also transmit any ASCII character from 000 to 255 by emulating the

PC technique of typing a character's ASCII number on the numeric pad while

holding down the Alt key. For example, to transmit ASCII 250, you would

scan the bar codes for:

Recheck all the connections. Get close to the Base Station. Try reading

the Link Test bar code, following the steps for scanning on page 8.

•

If you hear two beeps, but see nothing on the screen, and you are

reading the pocket card, you must read the ENTER bar code to have

anything transmitted. Any Code 39 or 128 bar code with leading spaces

(such as the Barpad on page 23) will not be transmitted to your

computer until you read a bar code without a leading space. Try

reading the Test Label on page 21 as an example of a known good label

without a leading space. If you have bar codes with leading spaces in

them, and you want them transmitted, you must disable Accumulate

Mode using the Setup Menu.

Serial Troubleshooting

The reader beeps on reads, but nothing appears on your screen using

PortKey OR nothing appears to your own software.

•

Recheck the installation instructions beginning on page 4 to make sure

all cables are properly connected.

•

If you're trying to read Code 39 bar codes with leading spaces (such as

the Barpad on page 23) and have enabled Accumulate Mode, those bar

codes will not be transmitted to your computer until you read a bar

code without a leading space. Try reading the Test Label on page 21 as

an example of a known good label.

•

If you're using PortKey on an IBM-compatible, verify that the readers

matches the program's COM port, baud rate, data bits, stop bits, and parity

If you're using your own software to read the serial port, verify that the

problem is not in your software. Run the WDR Serial Test Program

that shipped with your reader and see if it gets any data on the screen

when you read a bar code.

•

Use a "null modem" connector to test switching pins 2 and 3 on one or

more serial cables, or use a breakout box to modify your cable(s).

The reader doesn't beep when you try to read your bar codes.

•

Make sure the power adapter is plugged in.

•

Try reading a known good bar code -- the Test Label on page 21,

following the steps for proper scanning technique on page 8.

Appendix A

Changing Jumpers and Channels

You may want to change the channel on the Base Station or you may want to

set the unit to use a Serial Y Cable. To do so, open up the case.

Turn your Base unit upside-down and unscrew its single Phillips screw. If you

don't completely remove the screw you can use it as a lever to pull up on the

cover, otherwise insert a fingernail, credit card edge or small screwdriver

blade into the gap between the base and side of the case. Gently use it as a

lever to lift up the edge of the base, then grasp the edge of the base and open it

outward like a door.

This exposes the reader's circuit board, as shown on the next page. When

you've finished examining or changing jumper settings, put the reader case

back together by reversing the steps illustrated on this page.

To change the Channel (0-9 for USA and Canada), unplug the power supply

and use a small flat head screwdriver to move the rotary switch shown below

to the number of the channel you desire. Now simply put the case back

together and plug in the power supply. You should see channel number set+ 3

green flashes on the base's LED; i.e. channel 0 setting will flash 3 times --

channel 6 setting will flash 9 times.

Serial Users, if you are going to use the Serial Y Cable (F45-1), you will need

to change the JP2 (Jumper 2) from S to Y. This permits Half Duplex

transmissions and interface between a host and terminal.

Recharging the Batteries

The LZ400-RF Laser has a rechargeable lithium ion battery built-in.

When not in use, the RF Laser should be plugged into the supplied, regulated

Worth Data 5V power adapter (DO NOT USE ANY Supply Except Worth

Data), so that it will always be recharged. The built-in recharger is a smart

charger, so you can't overcharge the battery and ruin it. A full charge takes

about 3 hours.

If you ordered the USB interface, the F10 power supply included with the laser

is used for recharging, since USB does not usually require the power supply to

power the Base Station (see page 6). The serial configuration will require a

second Worth Data 5v power supply if you want to keep the Base Station

powered up at all times. You can get by with one power supply by simply

unplugging the Base Station so you can recharge the RF Laser Reader.

Specifications for Code 39

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 specifications).

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" (white space) to

*C39*

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 Laser Reader 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 39. The check

character is derived by assigning a value to each character in the data to be bar

coded from the table as follows:

Char

Table C-1. 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

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.

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

. Full ASCII 93 is created by

pairing these control characters with normal data characters. 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

M to produce the Carriage Return.

Code 93's two built-in check digits greatly minimize the possibility of reader

substitution errors. These check digits are never transmitted by the bar code

reader. 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.

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.

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.

a12345b

Codabar start/stop transmission

The Codabar section on the RF Laser Reader 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 Laser Reader and data coming from the

keyboard. If neither situation applies, 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 character that

12345

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, all variable

length fields are terminated by a Function Code 1 character unless they are the

last field in the bar code.

The RF Laser Reader 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).

Download from Www.Somanuals.com. All Manuals Search And Download.

The Mod 10 Check digit is calculated the same as the Interleaved 2 of 5

example in Appendix G. 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.

UCC/EAN 128 is enabled by scanning the appropriate bar codes on the RF

Laser Reader Setup Menu. 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

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 on UCC/EAN 128,

Appendix G

Interleaved 2 of 5 Code

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.

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:

123456

•

Use one length of I 2 of 5 code. Using one length of data allows

you to tell the RF Laser Reader to look for one length of I 2 of 5

code only. By default, the RF Laser Reader 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 Laser Reader Setup Menu. Setting the length to 00

digits allows variable length bar codes scanning but also

dramatically increases your chance of a mis-read.

•

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:

(7 + 9) x 3 = 48

5. Add the results of steps 3 and 4:

9 + 48 = 57

Download from Www.Somanuals.com. All Manuals Search And Download.

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 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:

8:00 a.m. to 6 p.m. EST

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 GS1 US. 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.

Download from Www.Somanuals.com. All Manuals Search And Download.

•

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 assigned by

the GS1 US. (Do not use 0 as the leading number for in-

store marking).

Store-marked random weight items of meat and produce.

Reserved for National Drug Code and Health Related Items.

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.

UPC 2 and 5-character supplemental codes

The UPC standards include the addition of a

2 or 5-character supplemental code used

with magazines and paperback books. To

read the supplements, you must first enable

them using the RF Laser Setup Menu.

NOTE: Enabling the supplements disallows

the reading of UPC codes from right to left

to assure that the supplement does not get missed.

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 Laser Reader 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:

18314589938

Assign even and odd positions, starting at the right and moving left:

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.

This same formula is used for EAN-13 (using the 1-12 digits) and EAN-8

(using the 1-7 digits).

UPC-E Checksum Calculation

Use the sample data of 123456 to demonstrate the UPC-E checksum

calculation:

1. The 6 digit UPC-E code is converted to a 10-digit code, using an

expansion scheme based on the sixth digit:

If the code

ends in:

Abcde00007

Abcde00008

Abcde00009

Because the sample UPC-E code ends in a 6, the insertion digits 0000 are

inserted at the sixth digit (insertion position 6):

1234500006

2. Add the Number System Character of 0 to the sample data:

01234500006

3. Use the UPC-A check digit calculation described in the previous

section to produce a check digit as if it were a UPC-A code. The

check digit for the sample data is:

4. The complete 8 digit code consists of the Number System Character,

the original 6 digit code and the check digit:

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

7. Data with check digit is:

823450

Download from Www.Somanuals.com. All Manuals Search And Download.

The MSI Mod 11 check digit is calculated as follows:

The example bar code data is:

943457842

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

(If the remainder is 10, no check digit is added.)

6. Data with check digit is:
