Codabar Options
The Codabar symbology has the following programmable features:
Check Digit
— calculates the Check Digit to verify the label's contents
have been read correctly. If you enable this feature, your bar codes must
include a Check Digit. You may also choose to transmit or not
transmit the Check Digit.
Start/Stop Characters
— you can choose either Send or Don't Send
depending on your host's interface requirement.
Start/Stop Format
— if you need to send the Start/Stop characters, there
are four standard format options that you can select from; ABCD/
TN*E, ABCD/ABCD, abcd/tn*e, or abcd/abcd. This setting must
match your system requirements. If you select one of these options, it
determines how the ASCII characters A, B, C, D that are used for
Start/Stop characters, will be translated before being sent to the host.
Start/Stop Match
— the requirement that the Start and Stop characters
must match (be identical) can be enabled or disabled.
Label Format
— provides the selection between fixed or variable length
labels. If your application has labels with specific fixed length, we
recommend selecting fixed lengths to improve read rate.
If you select variable length, the scanner will recognize labels with between
03 and 47 digits
1
(not including the optional check digit).
Set First Fixed Length
— if you select fixed length, use this feature
to set a first fixed label length to a setting between 03 and 50
*
digits.
Set Second Fixed Length
— if you select fixed length, use this
feature to set a second fixed label length to a setting between 03 and 50
digits
1
.
No Second Fixed Length
— scan this label after setting the first
fixed length to instruct the scanner to recognize only the label length
chosen as the first label length.
Gap Check
— allows the scanner to combine two label halves printed in
close proximity to each other that may have been printed at different
times and perhaps different locations.

The scanner will decode up to 50 characters, but the actual length read will vary
depending upon bar code size and quality. The IBM POS interface is limited to 32
character labels.
