8-21-5 Fixing the Length of Code 39 (0x12/0x13)
Length for Code 39 may be set for “Any Length”, “One Discrete Length”, “Two Discrete Lengths”,
or “Length within a Range”.
The length of a code refers to the number of characters including check digits that the code
contains. If Code 39 Full ASCII is enabled, “Length within a Range” or “Any Length” are the
preferred options.
Fixing to One Discrete Length:
This option limits decodes to only those Code 39 bar codes containing a selected length.
Length is selected from the numeric bar codes on page 108. For example, to decode only Code
39 bar codes with 14 characters, scan
“
Code 39 – One Discrete Length” and then scan
numeric bar codes “1” followed by “4”.
(Note: Single digit numbers must always be preceded by a leading zero.)
To change the selection or cancel an incorrect entry, scan “Cancel” bar code on page 108.
Code 39 – One Discrete Length
Fixing to Two Discrete Lengths:
This option limits decodes to only those Code 39 bar codes containing either of two selected
lengths. Lengths are selected from the numeric bar codes on page 108. For example, to decode
only those Code 39 bar codes containing either 2 or 14 characters, select “Code 39 – Two
Discrete Lengths” and then scan numeric bar codes “0”, “2”, “1” and “4”.
(Note: Single digit numbers must always be preceded by a leading zero.)
To change the selection or cancel an incorrect entry, scan “Cancel” bar code on page 108.
Code 39 – Two Discrete Lengths
Fixing to Length within a Range:
This option limits decodes to only those Code 39 bar codes within a specified range. For
example, to decode Code 39 bar codes containing between 4 and 12 characters, first scan
“
Code 39 – Length within a Range” and then scan numeric bar codes of “0”, “4”, “1” and “2”.
(Note: Single digit numbers must always be preceded by a leading zero.)
To change the selection or cancel an incorrect entry, scan “Cancel” bar code on page 108.
Code 39 – Length within a Range
Fixing to Any Length:
Scan this option to decode Code 39 bar codes containing any number of characters.
Code 39 – Any Length
