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. Set lengths for Code 39 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.
One Discrete Length - This option allows the digital scanner to decode only those Code 39 symbols containing a
selected length. Use the numeric bar codes in
Appendix D, Numeric Bar Codes to select the length. For example,
to decode only Code 39 symbols with 14 characters, scan Code 39 - One Discrete Length, then scan 1 followed
by 4. In case of an error, or to change the selection, scan Cancel on
page D-3 .
Two Discrete Lengths - This option allows the digital scanner to decode only those Code 39 symbols
containing either of two selected lengths. Use the numeric bar codes in
Appendix D, Numeric Bar Codes to select
lengths. 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. In case of an error, or to change the selection, scan Cancel
on
page D-3 .
Length Within Range - This option allows the digital scanner to decode a Code 39 symbol within a specific
length range. Use the numeric bar codes in
Appendix D, Numeric Bar Codes to select the length range . 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). In case of an error, or to
change the selection, scan Cancel on
page D-3 .
Any Length - This option allows the digital scanner to decode Code 39 symbols containing any number of
characters within the digital scanner’s capability.
NOTE When setting lengths for different bar code types, enter a leading zero for single digit numbers.
