Set Lengths for Code 128
Parameter # L1 = D1h L2 = D2h
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 128 to any length, one or two discrete lengths, or lengths within a specific range.
•
One Discrete Length - Select this option to decode only Code 128 symbols containing a selected length. Select the
length using the numeric bar codes beginning on page 4-73. For example, to decode only Code 128 symbols with 14
characters, scan Code 128 - One Discrete Length, then scan 1 followed by 4. To correct an error or change the
selection, scan Cancel on page 4-74.
•
Two Discrete Lengths - Select this option to decode only Code 128 symbols containing either of two selected
lengths. Select lengths using the numeric bar codes beginning on page 4-73. For example, to decode only Code 128
symbols containing either 2 or 14 characters, select Code 128 - Two Discrete Lengths, then scan 0, 2, 1, and
then 4. To correct an error or change the selection, scan Cancel on page 4-74.
•
Length Within Range - Select this option to decode a Code 128 symbol with a specific length range. Select
lengths using numeric bar codes beginning on page 4-73. For example, to decode Code 128 symbols containing
between 4 and 12 characters, first scan Code 128 - 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 4-74.
•
Any Length - Select this option to decode Code 128 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.
