Set Lengths for Code 39
L1 = Parameter # 18
SSI # 12h
L2 = Parameter # 19
SSI # 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 Range or Any Length are the preferred options. Minimum
and maximum length range is from 0 - 80. The default minimum and maximum length range is from 1 - 55.
Scan one of the following bar codes to select a length option:
• One Discrete Length - Decode only Code 39 symbols containing a selected length. Select the length using
the 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, and then scan 1, 4. To correct an error or change the
selection, scan Cancel on page G-3.
• Two Discrete Lengths - Decode only Code 39 symbols containing either of two lengths. Select lengths
using the bar codes in Appendix G, Numeric Bar Codes. For example, to decode only Code 39 symbols
containing either 2 or 14 characters, scan Code 39 - Two Discrete Lengths, and then scan 0, 2, 1, 4. To
correct an error or change the selection, scan Cancel on page G-3.
• Length Within Range - Decode Code 39 symbols with a specific length range. Select lengths using the
bar codes in Appendix G, Numeric Bar Codes. For example, to decode Code 39 symbols containing
between 4 and 12 characters, scan Code 39 - Length Within Range, and then scan 0, 4, 1, 2. To correct an
error or change the selection, scan Cancel on page G-3.
• Any Length - Decode Code 39 symbols containing any number of characters within the scanner’s capability.
NOTE The maximum number of 1D bar code characters readable with scanner depends on the type of
symbology, type of characters (i.e., digits or letters), printing density, and quality. For reference, the
DS2278 reads 3.1 in wide, 10mil 1D bar codes printed with 1200dpi resolution and 80% contrast.
NOTE When setting lengths, enter a leading zero for single digit numbers.
