Message Length Description You are able to set the valid reading length of some of the barcode symbologies. If the data length of the scanned barcode doesn't match the valid reading length, the document reader will issue an error beep. You may wish to set the same value for minimum and maximum length to force the document reader to read fixed length barcode data. This helps reduce the chances of a misread. EXAMPLE: Decode only those barcodes with a count of 9-20 characters. Min. length = 09 Max. length = 20 EXAMPLE: Decode only those barcodes 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 barcodes included in the explanation of the symbology, then scan the digit value of the message length and Save barcodes 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 Codabar * On Off Codabar Start/Stop Characters Start/Stop characters identify the leading and trailing ends of the barcode. You may either transmit, or not transmit Start/Stop characters. Default = Don't Transmit. Transmit * Don't Transmit Codabar Check Character Codabar check characters are created using different "modulos." You can program the document reader to read only Codabar barcodes with Modulo 16 check characters. Default = No Check Character. No Check Character indicates that the document reader reads and transmits barcode data with or without a check character. When Check Character is set to Validate and Transmit, the document reader will only read Codabar barcodes printed with a check character, and will transmit this character at the end of the scanned data. 6 - 2

Message Length Description
You are able to set the valid reading length of some of the barcode symbologies.
If the data length of
the scanned barcode doesn’t match the valid reading length, the document reader will issue an error
beep.
You may wish to set the same value for minimum and maximum length to force the document
reader to read fixed length barcode data.
This helps reduce the chances of a misread.
EXAMPLE:
Decode only those barcodes with a count of 9-20 characters.
Min. length = 09
Max. length = 20
EXAMPLE:
Decode only those barcodes 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 barcodes included
in the explanation of the symbology, then scan the digit value of the message length and
Save
barcodes
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
Codabar Start/Stop Characters
Start/Stop characters identify the leading and trailing ends of the barcode. 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 document reader
to read only Codabar barcodes with Modulo 16 check characters.
Default = No Check Character.
No Check Character
indicates that the document reader reads and transmits barcode data with or with-
out a check character.
When Check Character is set to
Validate and Transmit
, the document reader will only read Codabar
barcodes printed with a check character, and will transmit this character at the end of the scanned data.
