Set Lengths for Discrete 2 of 5
The length of a code refers to the number of characters (i.e., human readable charac-
ters), including check digit(s) the code contains. Set lengths for Codabar to any length,
one or two discrete lengths, or lengths within a speci
fi
c range.
One Discrete Length
- Select this option to decode only Codabar symbols containing a
selected length. Select the length using the numeric barcodes in
Appendix D, Numeric
Barcodes
. For example, to decode only Codabar symbols with 14 characters, scan Codabar
-
One Discrete Length
, then scan 1 followed by 4. To correct an error or to change the
selection, scan Cancel barcode.
Two Discrete Lengths
- Select this option to decode only Codabar symbols containing
either of two selected lengths. Select lengths using the numeric barcodes in
Appendix D,
Numeric Barcodes
. For example, to decode only those Codabar symbols containing either
2 or 14 characters, select Codabar -
Two Discrete Lengths
, then scan 0, 2, 1, and then 4. To
correct an error or to change the selection, scan Cancel barcode.
Length Within Range
- Select this option to decode an Codabar symbol with a speci
fi
c
length range. Select lengths using numeric barcodes in
Appendix D, Numeric Barcodes
.
For example, to decode Codabar symbols containing between 4 and 12 characters,
fi
rst
scan Codabar -
Length Within Range
. Then scan 0, 4, 1, and 2 (single digit numbers must
always be preceded by a leading zero). To correct an error or change the selection, scan
Cancel barcode.
Any Length
- Scan this option to decode Codabar symbols containing any number of
characters within the decoder capability.
Please Note:
Due to the construction of the Codabar symbology, it is possible for a scan
line covering only a portion of the code to be interpreted as a complete scan, yielding less
data than is encoded in the bar code. To prevent this, select speci
fi
c lengths (Codabar -
One
Discrete Length - Two Discrete Lengths
) for Codabar applications.
