Set Lengths for MSI
Parameter # L1 = 1Eh, L2 = 1Fh
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, capture MSI - One Discrete Length, then capture followed by 4. To correct 
an error or to change the selection, capture Cancel on
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 
capture 02, 1, and then 4. To correct an error or to change the selection, capture Cancel on
Length Within Range - Select this option to decode a MSI symbol with a specific length range. Select 
lengths using numeric bar codes in 
For example, to decode MSI 
symbols containing between 4 and 12 characters, first capture MSI - Length Within Range. Then capture 
041, 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 MSI symbols containing any number of characters within the 
imager capability. 
NOTE
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.
