To enable or disable Interleaved 2 of 5, scan the appropriate bar code below, and select an Interleaved 2 of 5 
length.

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 for any length, one or two discrete lengths, or lengths within a specific 
range. 

One Discrete Length - This option allows the digital scanner to decode only those I 2 of 5 symbols containing a 
selected length. Use the numeric bar codes in 

 to select the length. For example, 

to decode only I 2 of 5 symbols with 14 characters, scan I 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

.

Two Discrete Lengths - This option allows the digital scanner to decode only those I 2 of 5 symbols 
containing either of two selected lengths. Use the numeric bar codes in 

 to select 

lengths. For example, to decode only I 2 of 5 symbols containing either 2 or 14 characters, select I 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

.

Length Within Range - This option allows the digital scanner to decode an I 2 of 5 symbol within a specific 
length range. Use the numeric bar codes in 

 to select the length range

. 

For 

example, to decode I 2 of 5 symbols containing between 4 and 12 characters, first scan I 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

.

Any Length - This option allows the digital scanner to decode I 2 of 5 symbols containing any number of 
characters within the digital scanner’s capability.

Due to the construction of the I 2 of 5 symbology, the digital scanner can interpret a scan line covering 
only a portion of the code 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.
