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 require- ments. 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 (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 be- tween 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.
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.
*For variable length symbologies, the QS6000/6000 Plus will decode up to 50 characters, but the actual length varies with label size and quality. The IBM POS interface is limited to 32 characters labels.
