Set Lengths for Interleaved 2 of 5
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 I 2 of 5 to any length, one or
two discrete lengths, or lengths within a specific range.
• One Discrete Length - Select this option to decode only I 2 of 5 bar codes containing a
selected length. Select the length using the numeric bar codes in scan the CANCEL bar
code located in
Appendix E, Keypad . For example, to decode only I 2 of 5 bar codes
with 14 characters, scan I 2 of 5 - 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 I 2 of 5 bar codes containing
either of two selected lengths. Select lengths using the numeric bar codes in
Appendix
E, Keypad . For example, to decode only those I 2 of 5 bar codes containing either 2 or
14 characters, select I 2 of 5 - 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 an I 2 of 5 bar code with a spe-
cific length range. Select lengths using numeric bar codes in
Appendix E, Keypad .
For example, to decode I 2 of 5 bar codes containing between 4 and 12 characters,
first scan I 2 of 5 - 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,
can the CANCEL bar code located in
Appendix E, Keypad .
• Any Length - Scan this option to decode I 2 of 5 bar codes containing any number of
characters within the scanner capability.
NOTE
Due to the construction of the I 2 of 5 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 (I 2 of 5 - One Discrete Length - Two Discrete Lengths) for I 2
of 5 applications.
