Discrete 2 of 5
Enable/Disable Discrete 2 of 5
To enable or disable Discrete 2 of 5, scan the appropriate bar code below.
Set Lengths for Discrete 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 D 2 of 5 to
any length, one or two discrete lengths, or lengths within a specific range. The
range for Discrete 2 of 5 lengths is 0 - 55.
One Discrete Length - Select this option to decode only D 2 of 5 symbols
containing a selected length. Select the length using the numeric bar codes in the
appendix of
Numeric Bar Codes . For example, to decode only D 2 of 5 symbols
with 14 characters, scan D 2 of 5
-
One Discrete Length , and then scan 1 followed
by 4 . To correct an error or to change the selection, scan the Cancel bar code.
Two Discrete Lengths - Select this option to decode only D 2 of 5 symbols
containing either of two selected lengths. Select lengths using the numeric bar
codes in the appendix of
Numeric Bar Codes . For example, to decode only D 2 of 5
symbols containing either 2 or 14 characters, select D 2 of 5 - Two Discrete
Lengths , and then scan 0 , 2 , 1 , and then 4 . To correct an error or to change the
selection, scan the Cancel bar code.
Length Within Range - Select this option to decode a D 2 of 5 symbol with a
specific length range. Select lengths using numeric bar codes in the appendix of
Numeric Bar Codes . For example, to decode D 2 of 5 symbols containing between
4 and 12 characters, first scan D 2 of 5 - Length Within Range . Then scan 0 , 4 , 1,
and 2 (enter a leading zero for single digit numbers). To correct an error or change
the selection, scan the Cancel bar code.
Any Length - Scan this option to decode D 2 of 5 symbols containing any
number of characters within the decoder’s capability.
Note: Due to the construction of the D 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 bar code. To prevent this, select specific lengths (
D 2
of 5 - One Discrete Length, Two Discrete Lengths ) for D 2 of 5 applications.
