Interleaved 2 of 5 (I 2 of 5)
Enable/Disable Interleaved 2 of 5
To enable or disable Interleaved 2 of 5, scan the appropriate bar code below, and select an Interleaved 2 of 5
length.
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 for any length, one or two discrete lengths, or lengths within a specific
range.
One Discrete Length - This option allows the digital scanner to decode only those I 2 of 5 symbols containing a
selected length. Use the numeric bar codes in Appendix D, Numeric Bar Codes to select the length. For example,
to decode only I 2 of 5 symbols with 14 characters, scan I 2 of 5 - One Discrete Length , then scan 1 followed by
4 . In case of an error, or to change the selection, scan Cancel on page D-3 .
Two Discrete Lengths - This option allows the digital scanner to decode only those I 2 of 5 symbols
containing either of two selected lengths. Use the numeric bar codes in Appendix D, Numeric Bar Codes to select
lengths. For example, to decode only I 2 of 5 symbols containing either 2 or 14 characters, select I 2 of 5 - Two
Discrete Lengths , then scan 0 , 2 , 1 , and then 4 . In case of an error, or to change the selection, scan Cancel
on page D-3 .
Length Within Range - This option allows the digital scanner to decode an I 2 of 5 symbol within a specific
length range. Use the numeric bar codes in Appendix D, Numeric Bar Codes to select the length range . For
example, to decode I 2 of 5 symbols containing between 4 and 12 characters, first scan I 2 of 5 - Length Within
Range . Then scan 0 , 4 , 1, and 2 (insert a leading zero for single digit numbers). In case of an error, or to change
the selection, scan Cancel on page D-3 .
Any Length - This option allows the digital scanner to decode I 2 of 5 symbols containing any number of
characters within the digital scanner’s capability.

NOTE
Due to the construction of the I 2 of 5 symbology, the digital scanner can interpret a scan line covering
only a portion of the code 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.
