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 the scanner to decode only those Code 39
symbols containing a selected length. Lengths are selected from the numeric bar codes
beginning on page D-1 in Chapter 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. In case of an error, or to change the selection, scan Cancel on page D-7.
Code 39 - One Discrete Length
Two Discrete Lengths - This option allows the scanner to decode 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 Chapter 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. In case of an error, or to change
the selection, scan Cancel on page D-7.
