Connecting the Scanner When Powered by Host

(Keyboard Wedge)

A scanner can be connected between the keyboard and PC as a “keyboard

wedge,” plugged into the serial port, or connected to a portable data terminal in

wand emulation or non decoded output mode. The following is an example of a

keyboard wedge connection:

1. Turn off power to the terminal/computer.

2. Disconnect the keyboard cable from the back of the terminal/computer,

as shown below.

Disconnect

3. Connect the appropriate interface cable to the scanner and to the

terminal/computer.

4. Turn the terminal/computer power back on. The scanner will beep

twice.

5. Verify the scanner operation by scanning a bar code from the back

cover of this manual. The scanner will beep once.

The scanner is now connected and ready to communicate with your

terminal/PC. You must program the scanner for your interface before bar code

data can be transmitted to your terminal/PC. If you are using the scanner as a

keyboard wedge, turn to page 2–1. If the scanner is connected via a serial

port, turn to page 2–8. If this is a wand emulation application, turn to page

2–13, and for a non decoded output connection, turn to page 6–2.

Wand Emulation Connection

In Wand Emulation mode, the scanner decodes the bar code then sends data

in the same format as a wand scanner. The Code 39 Format converts all

symbologies to Code 39. The Same Code Format transmits UPC, EAN, Code

128 and Interleaved 2 of 5 without any changes, but converts all other

symbologies to Code 39. These codes set the transmission rate to 25 inches

per second and the output polarity to black, high. Default = Code 39 Format.

Section 4

Data Editing

When a bar code is scanned, additional information is sent to the host

computer along with the bar code data. This group of bar code data and

additional, user-defined data is called a “message string.” The selections in this

section are used to build the user-defined data into the message string.

Prefix and Suffix characters are data characters that can be sent before and

after scanned data. You can specify if they should be sent with all

symbologies, or only with specific symbologies. The following illustration

shows the breakdown of a message string:

Prefix

Scanned Data

Suffix

Points to Keep In Mind

It is not necessary to build a message string. The selections in this chapter

are only used if you wish to alter the default settings. Default prefix = None.

Default suffix = None.

A prefix or suffix may be added or cleared from one symbology or all

symbologies.

You can add any prefix or suffix from the ASCII chart (pg. 4–5 ), plus Code

I.D. and Aim I.D.

You can string together several entries for several symbologies at one time.

Enter prefixes and suffixes in the order in which you want them to appear on

the output.

Some terminals drop information (characters) if data comes through too quickly.

Intercharacter, interfunction, and intermessage delays slow the transmission of

data, which increases data integrity.

Each delay is composed of a 5 millisecond step. You can program up to 99

steps (of 5 ms each).

Intercharacter Delay

This is a delay of up to 495 milliseconds (in multiples of 5) placed between the

transmission of each character of scanned data. You can program up to 99

steps (of 5 ms each). Scan the Intercharacter Delay bar code below, then scan

the number of steps, and the SAVE bar code from the inside back cover.

Note: If you make an error while scanning the digits (before scanning

Data Formatting

Data Format Editor

The Data Format Editor selections are used to edit scanned data. For

example, you can use the Data Format Editor to insert characters at certain

points in bar code data as it is scanned.

It is not necessary to use the Data Format Editor. A set of defaults for the data

format is already programmed in the scanner. The selections in the following

pages are used only if you wish to alter the default settings. Default Data

Format setting = none.

If you have changed data format settings, and wish to clear all formats and

return to the defaults, scan the Default Data Format code.

To Add a Data Format

STEP 1. Scan the Enter Data Format symbol (pg. 5–4).

STEP 2. Primary/Alternate Format

Determine if this will be your primary data format, or one of 3

alternate formats. (Alternate formats allow you “single shot”

capability to scan one bar code using a different data format. After

the one bar code has been read, the scanner reverts to the primary

data format. See page 5–6.) If you are programming the primary

format, scan 0. If you are programming an alternate format, scan 1,

2, or 3, depending on the alternate format you are programming.

STEP 3. Terminal Type

Refer to the Supported Terminals Chart (page 2–3) and locate the

Terminal ID number for your PC. Scan three numeric bar codes on

the inside back cover to program the scanner for your terminal ID

(you must enter 3 digits). For example, scan 0 0 3 for an AT wedge.

STEP 4. Code I.D.

On pg. 4–5, find the symbology to which you want to apply the data

format. Locate the Hex value for that symbology and scan the 2 digit

hex value from the Programming Chart.

STEP 5. Length

Specify what length (up to 9999 characters) of data will be acceptable

for this symbology. Scan the four digit data length from the

Programming Chart. (Note: 50 characters is entered as 0050. 9999

is a universal number, indicating all lengths.)

STEP 6. Editor Commands

Refer to the Format Editor Commands Chart (page 5–2). Scan the

symbols that represent the command you want to enter. 94

alphanumeric characters may be entered for each symbology data

format.

STEP 7. Scan Save to save your entries.

Secondary Interface

By switching interface cables, the 7837 scanner can communicate with a

portable data terminal (secondary interface), in addition to the host terminal

(primary interface).

The secondary interface can be programmed at any time.

Secondary Code 39 Wand Emulation

In Wand Emulation mode, the scanner decodes the bar code then sends data

in the same format as a wand scanner. The Code 39 Format converts all

symbologies to Code 39. The Same Code Format transmits UPC, EAN, Code

128 and Interleaved 2 of 5 without any changes, but converts all other

symbologies to Code 39. These codes set the transmission rate to 25 inches

per second and the output polarity to black, high. Default = Code 39 Format.

RS-232 programmable selections are used by both the primary and secondary

interfaces. Changing an RS-232 parameter (e.g., baud rate or parity), while in

primary or secondary mode will affect both interfaces.

Manual Trigger, Low Power: The scanner “sleeps,” using only 5 microamps,

until the trigger is pulled. When the trigger is pulled, the scanner wakes up and

operates at reduced power until there is no triggering for the time set with the

Low Power Time Out bar code. There is a short delay in operation when the

scanner is first triggered, but there is no delay when operating in low power

mode.

Low Power Time Out: Scan the Low Power Time Out bar code to change the

time out duration. Then scan the time out duration (from 0–300 seconds) from

the inside back cover and Save. Default = 2 minutes.

Note:

If you make an error while scanning the digits (before scanning Save),

scan Discard on the back cover, scan the Low Power Time Out bar

code, scan the correct digits, and Save again.

Cod e 39 Ap p e nd

This function allows the scanner to append the data from several Code 39 bar

codes together before transmitting them to the host computer. When this

function is enabled, the scanner stores those Code 39 bar codes that start with

a space (excluding the start and stop symbols), and does not immediately

transmit the data. The scanner stores the data in the order in which the bar

codes are read, deleting the first space from each. The scanner transmits the

appended data when it reads a Code 39 bar code that starts with a character

other than a space. Default = Off.

Different types of check characters are used with MSI bar codes. You can

program the scanner to read only MSI bar codes with Type 10 or Type 11 check

characters. Default = Validate Type 10, but Don’t Transmit.

When Check Character is set to Validate and Transmit, the scanner will only

read MSI bar codes printed with the specified type check character, and will

transmit this character at the end of the scanned data.

When Check Character is set to Validate, but Don’t Transmit, the unit will only

read MSI bar codes printed with the specified type check character, but will not

transmit the check character with the scanned data.

Message Length

The message length selection is used to set the valid reading length of the bar

code. You may wish to set the same value for minimum and maximum length

to force the scanner to read fixed length bar code data. This helps reduce the

chances of a misread.

EXAMPLE:

Decode only those bar codes with a count of 9–20 characters.

Min. length = 09 Max. length = 20

EXAMPLE:

Decode only those bar codes with a count of 15 characters.

Min. length = 15 Max. length = 15

For a value other than the minimum and maximum message length defaults,

scan the bar codes below and then scan the 2–digit value and Save bar codes

on the Programming Chart inside back cover. Minimum and Maximum

Lengths = 4–48.

Note:

If you make an error while scanning the digits (before scanning Save),

scan Discard on the back cover, scan the Minimum or Maximum bar

code, scan the correct digits, and Save again.

Maximum (Default =48)

Section 8

Cloning

The cloning procedure reprograms the software in the “destination” scanner’s

memory with software from the “source” scanner. Before using this procedure,

determine which scanner will be the source (the scanner containing the desired

software). The 7837 supports cloning and can act as the source device. The

software in the destination scanner will be updated from the source scanner.

The destination scanner device must be the same model as the source.

Procedure:

Use the cloning cable (42204559–01) to connect the two scanners

for cloning.

Connect the destination scanner to one of the 10 pin modular

connectors on the cloning cable.

Connect the source scanner (containing the new or updated

software) to the remaining 10 pin modular connector on the cloning

cable.

Connect the power supply to the 4 pin mini–DIN connector located

on the cloning cable or the scanner cable.

Make sure both units are on, and then scan the “Clone Destination”

bar code with the destination scanner.

Clone Destination Bar Code

Scan the Clone Source bar code below with the source scanner.

The scanner’s “Good Read” LED begins blinking periodically

indicating cloning is in process.

Clone Source Bar Code

When cloning is complete, the destination scanner will double beep.

This procedure takes approximately two minutes.

Disconnect the destination scanner from the cloning cable.

To clone another scanner, repeat steps 1 through 8.

Caution: DO NOT scan the “source” bar code unless you are

going to clone a scanner. If you mistakenly scan this

bar code, reset the scanner by turning the power off

and back on to regain normal operation.
