Set Lengths for Interleaved 2 of 5
Parameter # L1 = 22 (SSI # 16h), L2 = 23 (SSI # 17h)
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 symbols containing a selected length.
Select the length using the numeric bar codes in Appendix G, Numeric Bar Codes. 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. To correct an error or to change the selection, scan Cancel on page G-3.
•
Two Discrete Lengths - Select this option to decode only I 2 of 5 symbols containing either of two
selected lengths. Select lengths using the numeric bar codes in Appendix G, Numeric Bar Codes. For
example, to decode only those 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. To correct an error or to change the selection,
scan Cancel on page G-3.
•
Length Within Range - Select this option to decode an I 2 of 5 symbol with a specific length
range. Select lengths using numeric bar codes in Appendix G, Numeric Bar Codes. 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 (single digit numbers must always be preceded by a leading zero). To
correct an error or change the selection, scan Cancel on page G-3.
•
Any Length - Scan this option to decode I 2 of 5 symbols containing any number of characters within the
imager’s 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.
I 2 of 5 - One Discrete Length
I 2 of 5 - Two Discrete Lengths
