11 - 40 Symbol MS4404/MS4407 Integration Guide

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 I 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 I 2 of 5 symbols containing a selected length. Select 
the length using the numeric bar codes in 

. For example, to decode only I 2 

of 5 symbols with 14 characters, capture I 2 of 5 - One Discrete Length, then capture 1 followed by 4. To 
correct an error or to change the selection, capture Cancel on

 page D-3.

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

. For 

example, to decode only those I 2 of 5 symbols containing either 2 or 14 characters, select I 2 of 5 - Two 
Discrete Lengths, then capture 0, 2, 1, and then 4. To correct an error or to change the selection, 
capture Cancel on

.

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

For example, to decode I 2 of 

5 symbols containing between 4 and 12 characters, first capture I 2 of 5 - Length Within Range. Then 
capture 0, 4, 1, and 2 (single digit numbers must always be preceded by a leading zero). To correct an error 
or change the selection, capture Cancel on

.

Any Length - Capture this option to decode I 2 of 5 symbols containing any number of characters within the 
imager capability.

Due to the construction of the I 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 (I 2 of 5 - One Discrete Length - Two Discrete Lengths) for I 2 of 5 applications.
