Set Lengths for Interleaved 2 of 5
Parameter # L1 = 16h, L2 = 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 D, 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 D-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 D, 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 D-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 D, 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 D-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
