Codabar Options
The Codabar symbology has the following programmable features:
• Check Digit
•
Gap Check
• Label Length Format
• Start/Stop Character
• Start/Stop Match
• Start/Stop Format
• Read Verification
• QuadraLogic™ II Decoding
Check Digit
Check Digit calculates the Check Digit to verify the label’s contents
have been read correctly. If you enable this feature, your labels must
include a Check Digit. You may also choose to transmit or not transmit
the Check Digit.
If the Check Digit is not calculated, the digit will be sent regardless of
settings for transmit or don’t transmit. For example, if you choose to
Transmit Check Digit, but not calculate, the scanner sends the Check
Digit encoded in the label without verifying its accuracy.
Gap Check Disabling 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.
Label Length
Format
Label length format permits the selection between variable length or
fixed length formats. For best performance it is recomended to use the
Fixed Length settings when your application requires only one or two
label lengths.
Variable Length Format
- directs the scanner to read all labels from
minimum label length to 50. Set Minimum Length as high as your
application allows.
Minimum Label Length - selects the minimum label length
that the scanner will recognize. The minimum label length for
this symbology must be between 03 and 50
1
.
Fixed length Format - directs the scanner to read only one or two label
lengths.
1. For this symbology, the scanner will decode up to 50 characters, but the actual length read will
vary depending upon the interface type, and bar code physical size and quality.
