Set Lengths for Discrete 2 of 5
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 D 2 of 5 may be set for any length, one or two discrete lengths, or lengths within a specific range.
One Discrete Length - This option allows the scanner to decode only those D 2 of 5 symbols containing a selected length. Lengths
are selected from the numeric bar codes in Appendix D, Numeric Bar Codes . For example, to decode only D 2 of 5 symbols with 14
characters, scan D 2 of 5 - One Discrete Length , then scan 1 followed by 4 . In case of an error, or to change the selection, scan
Cancel on page D-5 .
D 2 of 5 - One Discrete Length
Two Discrete Lengths - This option allows the scanner to decode only those D 2 of 5 symbols containing either of two
selected lengths. Lengths are selected from the numeric bar codes in Appendix D, Numeric Bar Codes . For example, to decode only
those D 2 of 5 symbols containing either 2 or 14 characters, select D 2 of 5 - 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-5 .
D 2 of 5 - Two Discrete Lengths
Length Within Range - This option allows the scanner to decode a D 2 of 5 symbol with a specific length range. The length
range is selected from numeric bar codes in Appendix D, Numeric Bar Codes . For example, to decode D 2 of 5 symbols
containing between 4 and 12 characters, first scan D 2 of 5 - Length Within Range . Then scan 0 , 4 , 1, and 2 (insert a leading zero
for single digit numbers). In case of an error, or to change the selection, scan Cancel on page D-5 .
D 2 of 5 - Length Within Range
Any Length - This option allows the scanner to decode D 2 of 5 symbols containing any number of characters within the scanner
capability.
Due to the construction of the D 2 of 5 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 actually encoded in the bar code. To
prevent this from happening, select specific lengths (
D 2 of 5 - One Discrete Length - Two Discrete
Lengths ) for D 2 of 5 applications.
D 2 of 5 - Any Length
