12 - 54 DS8178 Digital Scanner Product Reference Guide
Set Lengths for MSI
Parameter # L1 = 30 (SSI # 1Eh), L2 = 31 (SSI # 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.
The default is 4 to 55.
•
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 G, Numeric Bar Codes. 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 H-1.
•
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 G, Numeric Bar Codes. 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 H-1.
•
Length Within Range - Select this option to decode a MSI symbol with a specific length range. Select
lengths using numeric bar codes in Appendix G, 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 (enter a leading zero for single digit numbers). To correct an error or change the selection, scan
Cancel on page H-1.
•
Any Length - Scan this option to decode MSI symbols containing any number of characters within the digital
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 transmit 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.
MSI - One Discrete Length
MSI - Two Discrete Lengths
*MSI - Length Within Range
MSI - Any Length
