Message Length Description
You are able to set the valid reading length of some of the bar code symbologies. If the data
length of the scanned bar code doesn‟t match the valid reading length, the imager will issue an
error beep. You may wish to set the same value for minimum and maximum length to force the
imager 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
included in the explanation of the symbology, then scan the digit value of the message length and
Save bar codes on the Programming Chart inside the back cover of this manual. The minimum
and maximum lengths and the defaults are included with the respective symbologies.
Codabar
Default
Codabar Enabled
Codabar Start/Stop Characters
Start/Stop characters identify the leading and trailing ends of the bar code. You may either
transmit, or not transmit Start/Stop characters. Default = Don‟t Transmit.
Codabar Check Character
Codabar check characters are created using different “modulos.” You can program the imager to
read only Codabar bar codes with Modulo 16 check characters. Default = No Check Character.
No Check Character indicates that the imager reads and transmits bar code data with or without
a check character.
