Parameter # L1 = 0x1E, L2 = 0x1F
The length of a code refers to the number of characters (i.e., human read-
able characters) the code contains, and includes check digits. Lengths
for MSI can be set for any length, one or two discrete lengths, or lengths
within a specific range. See Table B-5 on page B-9 for ASCII equivalents.
MSI - One Discrete Length
MSI - Two Discrete Lengths
MSI - Length Within Range
•

- Select this option to decode only those codes
containing a selected length. For example, select
MSI Plessey
-
One
Discrete Length
, then scan

- Select this option to decode only those
codes containing two selected lengths. For example, select
MSI
Plessey
-
