Code 39
Warrington Hand-Held Computer User Manual 141
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 this parameter displays a dialog box 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 1 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.
Transmit Check Digit
If the check digit is to be transmitted with the data, this parameter must to enabled.
Full ASCII
If this parameter is enabled, the characters +, %, and / are used as escape characters. The
combination of an escape character and the next character is converted to an equivalent
ASCII character.
Note: Only those “Code 39” symbols that include a Mod 43 check digit are decoded when
this parameter is enabled.
