Set Lengths for Code 39
he 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.
When setting lengths for different bar code types by scanning single digit numbers, single digit numbers must
always be preceded by a leading zero.
•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 D, 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 D-4.
•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 D, Numeric Bar Codes. For example, to decode only those 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 D-4.
•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 D, 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 (single digit numbers
must always be preceded by a leading zero). To correct an err or or ch ange the selection, scan Cancel on page D-4.
•Any Length - Select this option to decode Code 39 symbols containing any number of characters within the scanner
capability.
