Msi Check Digits - Motorola LS3578 Product Reference Manual

11 - 44 LS3578 Product Reference Guide
Set Lengths for MSI (continued)
Any Length - This option allows the scanner to decode MSI symbols containing any number of characters within
the scanner 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 actually encoded in the bar code. To
prevent this from happening, select specific lengths (MSI - One Discrete Length - Two Discrete
Lengths) for MSI applications.

MSI Check Digits

With MSI symbols, one check digit is mandatory and always verified by the reader. The second check digit is
optional. If the MSI codes include two check digits, enable the verification of the second check digit by scanning the
bar code below.
See MSI Check Digit Algorithm on page 11-45
MSI - Any Length
for the selection of second digit algorithms.
