Set Lengths for MSI
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 bar codes containing a
selected length. Select the length using the numeric bar codes in
Appendix E, Keypad .
For example, to decode only MSI bar codes with 14 characters, scan MSI - One Discrete
Length, then scan 1 followed by 4. To correct an error or to change the selection, scan
the CANCEL bar code located in
Appendix E, Keypad .
• Two Discrete Lengths - Select this option to decode only MSI bar codes containing
either of two selected lengths. Select lengths using the numeric bar codes in
Appendix
E, Keypad . For example, to decode only MSI bar codes containing either 2 or 14 charac-
ters, select MSI - Two Discrete Lengths, then scan 0, 2, 1, and then 4. To correct an
error or to change the selection, scan the CANCEL bar code located in
Appendix E,
Keypad .
• Length Within Range - Select this option to decode a MSI bar code with a specific
length range. Select lengths using numeric bar codes in
Appendix E, Keypad . For
example, to decode MSI bar codes containing between 4 and 12 characters, first scan
MSI - 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 the selection, scan the
CANCEL bar code located in
Appendix E, Keypad .
• Any Length - Scan this option to decode MSI bar codes containing any number of charac-
ters within the 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 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.
