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. Lengths for D 2 of 5 may be set for any length, one or two discrete lengths, or lengths within a
specific range.

One Discrete Length - This option allows the scanner to decode only those D 2 of 5 symbols containing a
selected length. Lengths are selected from the numeric bar codes in

Appendix D, Numeric Bar Codes

. For

example, to decode only D 2 of 5 symbols with 14 characters, scan D 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

.

D 2 of 5 - One Discrete Length

Two Discrete Lengths - This option allows the scanner to decode only those D 2 of 5 symbols containing
either of two selected lengths. Lengths are selected from the numeric bar codes in

Appendix D, Numeric Bar

Codes

. For example, to decode only those D 2 of 5 symbols containing either 2 or 14 characters, select D 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

.

D 2 of 5 - Two Discrete Lengths

Length Within Range - This option allows the scanner to decode a D 2 of 5 symbol with a specific length
range. The length range is selected from numeric bar codes in

Appendix D, 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 (insert a leading zero for single digit numbers). In case of an error, or to change the
selection, scan Cancel on

page D-3

.

D 2 of 5 - Length Within Range

Any Length - This option allows the scanner to decode D 2 of 5 symbols containing any number of characters
within the scanner capability.

D 2 of 5 - Any Length

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 be interpreted as a complete scan, yielding less data than is actually encoded in the bar code.
To prevent this from happening, select specific lengths (D 2 of 5 - One Discrete Length - Two Discrete
Lengths
) for D 2 of 5 applications.
