Set Lengths for MSI
The length of a code refers to the number of characters (i.e., hu man readable characters), including check digit(s)
the code contains. Set lengths for MSI for any length, one o r two discrete lengths, or lengths within a specific
range.
One Discrete Length - Select this option to decode only MSI symbols containing a se lected length. Select the
length using the numeric bar codes in Appendix D, Numeric Bar Codes. Fo r 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 change a
selection, scan Cancel on page D-3.
MSI - One Discrete Length
Two Discrete Lengths - Select this option to decode only MSI symbols c o n ta i ning eith e r o f t w o s e l e c t e d
lengths. Select the lengths using the numeric bar codes in Appendix D, Numeric Bar Codes. For example, to
decode only those MSI symbols containing either 2 or 14 characte rs, select MSI - Two Discrete Lengths, then
scan 0, 2, 1, and then 4. To correct an error or change a selection, scan Cancel on page D-3.
MSI - Two Discrete Lengths
Length Within Range - Select this option to decode an MSI symbol with a specific length range. Select the
length range using the numeric bar codes in Appendix D, Nu meric Bar Codes. For example, to decode MSI
symbol s conta ining between 4 and 12 characters, first scan MS I - 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 a selection,
scan Cancel on page D-3.
MSI - Length Within Range
Any Length - Scan this option to decode MSI symbols containing any number of characters within the scanner’s
capability.
MSI - Any Length
NOTE Due to the construction of the MSI symbology, it is possible for a scan line covering only a portion of the
code to transmit as a complete scan, yielding less data than is encoded in the bar code. To prevent this,
Motorola recommends selecting specific lengths (MSI - One Discrete Length, Two Discrete Lengths) for
MSI applications.
