Symbologies 8 - 35

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 D 2 of 5 to any length, one or two discrete lengths, or lengths within a specific 
range.

One Discrete Length - Select this option to decode only D 2 of 5 symbols containing a selected length. 
Select the length using the numeric bar codes in 

. 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. 
To correct an error or to change the selection, scan Cancel on 

page D-3.

Two Discrete Lengths - Select this option to decode only D 2 of 5 symbols containing either of two 
selected lengths. Select lengths using the numeric bar codes in 

. 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. To correct an error or to change the selection, scan 
Cancel on 

Length Within Range - Select this option to decode a D 2 of 5 symbol with a specific length range. 
Select lengths using numeric bar codes in 

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 (single digit numbers must always be preceded by a leading zero). To correct an error or 
change the selection, scan Cancel on 

Any Length - Scan this option 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 encoded in the bar code. To 
prevent this, select specific lengths (D 2 of 5 - One Discrete Length - Two Discrete Lengths) for D 2 of 
5 applications.
