Symbologies 7-45

To enable or disable MSI, scan the appropriate bar code below.

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

•

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

. For example, to decode only MSI 

symbols with 14 characters, scan MSI - One Discrete Length, then scan 1 followed by 4. To correct an error 
or to change the selection, scan Cancel on page 

C-4.

•

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

. For example, to decode 

only MSI symbols containing either 2 or 14 characters, select MSI - Two Discrete Lengths, then scan 0, 2, 
1, and then 4. To correct an error or to change the selection, scan Cancel on page 

C-4

.

•

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

Appendix C, Numeric Bar Codes. 

For example, to decode MSI symbols 

containing between 4 and 12 characters, first scan MSI - 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 page 

C-4.

•

Any Length - Scan this option to decode MSI symbols containing any number of characters within the scanner 
capability. 

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