Code 39
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.
Figure 5.76 Setting Code Lengths
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.
Note: Only those "Code 39" symbols that include a Mod 43 check digit are
decoded when this parameter is enabled.
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.
