Set Lengths for MSIParameter # 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 Appendix D, Numeric Bar Codes. For example, to decode only MSI
symbols with 14 characters, capture MSI - One Discrete Length, then capture 1 followed by 4. To correct
an error or to change the selection, capture Cancel on page D-3.
•
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 Appendix D, Numeric Bar Codes. For example, to
decode only MSI symbols containing either 2 or 14 characters, select MSI - Two Discrete Lengths, then
capture 0, 2, 1, and then 4. To correct an error or to change the selection, capture Cancel on page D-3.
•
Length Within Range - Select this option to decode a MSI symbol with a specific length range. Select
lengths using numeric b a r c o d e s in Appendix D, Numeric Bar Codes. For example, to decode M SI
symbols contain ing between 4 and 12 characters, first capture MSI - Length Within Range. Then capture
0, 4, 1, and 2 (single digit numbers must always be preceded by a leading zero). To correct a n error or
change the selection, capture Cancel on page D-3.
•
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.
