Set Length(s) for Code 39

Parameter # L1 = 12h, L2 = 13h

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 option is Any Length. The range is 1 to 80.

•

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 E, 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 E-3.

•

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 E, 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 E-3.

•

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 E, 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 E-3.

•

Any Length - Select this option to decode Code 39 symbols containing any number of characters within

the linear imager’s capability. This is the default option.

NOTE When setting lengths for different bar code types, enter a leading zero for single digit numbers.
