Appendix C: Bar Code Settings

Decoded (Internal) Scanners

Code 39

Code 32 Prefix

When this parameter is enabled, the prefix character “A” is added to all “Code 32”

bar codes.

Set Length L1 And Set Length L2

Lengths for “Code 39” can be set for Any length, Length within a range, One discrete length

or Two discrete lengths. The length of a code refers to the number of characters (i.e., human

readable characters), including check digit(s).

Double-tapping on these parameters displays dialog boxes labelled Set Code Lengths where

you can define the code length that will be decoded by your scanner.

Choosing One discrete length allows you to decode only those codes containing a selected

length. Choosing Two discrete lengths allows you to decode only those codes containing two

selected lengths. Length within a range allows you to decode a code type within a specified

range from 2 to 55.

Check Digit Verification

When this parameter is enabled, the integrity of a “Code 39” symbol is checked to ensure

that it complies with specified algorithms.

Note: “Convert to Code 32” must be enabled in order for this parameter to function.

Note: Only those “Code 39” symbols that include a MOD 43 check digit are decoded

when this parameter is enabled.
