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 barcodes in <em_Emphasis><bl_blue>Appendix G, Numeric
Barcodes. 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
<bl_blue><em_Emphasis>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 barcodes in <em_Emphasis><bl_blue>Appendix
G, Numeric Barcodes. 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 <bl_blue><em_Emphasis>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 barcodes in <em_Emphasis><bl_blue>Appendix G, Numeric
Barcodes. 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 <bl_blue><em_Emphasis>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 barcode. To prevent this,
select specific lengths (MSI - One Discrete Length, Two Discrete Lengths) for MSI applications.
