Set Lengths for Code 39
The length of a code refers to the number of characters (i.e., human readable characters), including check digit(s) the code contains.
Lengths for Code 39 may be set for 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 - This option allows decoding of only those Code 39 symbols containing a selected length. Lengths are
selected from the numeric bar codes beginning on page D-1 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. If an error occurs, or to change the
selection, scan Cancel on page D-8.
Code 39 - One Discrete Length
Two Discrete Lengths - This option allows decoding of only those Code 39 symbols containing either of two selected lengths.
Lengths are selected from the numeric bar codes beginning on page D-1 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. If an error occurs, or to change the selection, scan Cancel on page D-8.
