Set Lengths for Code 39
Parameter # 18, 19
The length of a code refers to the number of characters (i.e., human readable characters), including check
digit(s) the code contains. Set lengths for Code 39 to any length, one or two discrete lengths, or lengths within
a specific range. If Code 39 Full ASCII is enabled,
Length Within a Range or Any Length are the preferred
options. The default is 1 to 55.
•
One Discrete Length - Select this option to decode only Code 39 symbols containing a selected length.
Select the length using the numeric bar codes in Appendix G, Numeric Bar Codes . For example, to
decode only Code 39 symbols with 14 characters, scan Code 39 - One Discrete Length , then scan 1
followed by 4 . To correct an error or change the selection, scan Cancel on page G-2 .
•
Two Discrete Lengths - Select this option to decode only Code 39 symbols containing either of two
selected lengths. Select lengths using the numeric bar codes in Appendix G, Numeric Bar Codes . For
example, to decode only Code 39 symbols containing either 2 or 14 characters, select Code 39 - Two
Discrete Lengths , then scan 0 , 2 , 1 , and then 4 . To correct an error or change the selection, scan
Cancel on page G-2 .
•
Length Within Range - Select this option to decode a Code 39 symbol with a specific length
range. Select lengths using numeric bar codes in Appendix G, Numeric Bar Codes . For example, to
decode Code 39 symbols containing between 4 and 12 characters, first scan Code 39 - Length
Within Range . Then scan 0 , 4 , 1, and 2 (enter a leading zero for single digit numbers). To correct an
error or change the selection, scan Cancel on page G-2 .
