Code 39 Stitch Check Digit
This parameter permits tag lengths containing a Code 39 Check Digit to be stitched if
Code 39 Stitch Enable is active.
Check Digit Length1 and Length2
These Check Digit lengths are programmed to permit specific length of Code 39 tag to
require a Code 39 Check Digit. These can be any length in the range of 01 ‐ 36 and are
not required to be in the range of C39 Minimum Length and C39 Maximum Length
programming.
Scans Required
This parameter sets the number of scans required to read a Code 39 bar code.
Increasing the number of scans can improve reading nominal bar codes. There are
four settings: 1 scan, 2 scans, 3 scans, and 4 scans. The default is 1 scan. Set this
parameter by scanning the appropriate Hex tag ( Hex 1 to Hex 4) .
Overlap Characters
This parameter sets the minimum number of characters which each segment must
contain when tag stitching is done. There are four settings: 1 overlap character (Hex
1) , 2 overlap characters (Hex 2) (default), 3 overlap characters (Hex 3) , and 4 overlap
characters
(Hex 4) . Set this parameter by scanning the appropriate Hex tag ( Hex 1 to Hex 4 ).
Minimum Segment Size
This parameter sets the minimum number of characters which each segment must
contain when tag stitching is done. Set this parameter by scanning the appropriate
Hex tag ( Hex 2 to Hex 9 ). The default is
Hex 3 .
