Set Lengths for Interleaved 2 of 5
L1 = Parameter # 22
SSI # 16h
L2 = Parameter # 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. The range for Interleaved 2 of 5 lengths is 0 - 80. The default is
Length Within Range: 6 to 55.
Scan one of the following barcodes to select a length option:
• One Discrete Length - Decode only I 2 of 5 symbols containing a selected length. Select the length using
the barcodes in Numeric Barcodes. For example, to decode only I 2 of 5 symbols with 14 characters,
scan I 2 of 5 - One Discrete Length, and then scan 1, 4. To correct an error or change the selection,
scan Cancel on page 426.
• Two Discrete Lengths - Decode only I 2 of 5 symbols containing either of two lengths. Select lengths
using the barcodes in Numeric Barcodes. For example, to decode only I 2 of 5 symbols containing either
2 or 14 characters, scan I 2 of 5 - Two Discrete Lengths, and then scan 0, 2, 1, 4. To correct an error
or change the selection, scan Cancel on page 426.
• Length Within Range - Decode I 2 of 5 symbols with a specific length range. Select lengths using the
barcodes in Numeric Barcodes. For example, to decode I 2 of 5 symbols containing between 4 and 12
characters, scan I 2 of 5 - Length Within Range, and then scan 0, 4, 1, 2. To correct an error or change
the selection, scan Cancel on page 426.
• Any Length - Decode I 2 of 5 symbols containing any number of characters within the scanner’s
capability.
NOTE: When setting lengths, enter a leading zero for single digit numbers.
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 transmit as a complete scan, yielding less data than is encoded in the barcode. To prevent this,
select specific lengths (I 2 of 5 - One Discrete Length, Two Discrete Lengths) for I 2 of 5 applications, or
increase the I 2 of 5 Security Level on page 173.
