Set Lengths for Discrete 2 of 5 (continued)
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
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
Length Within Range - This option allows the scanner to decode an D 2 of 5 symbol with a specific
length range. The length range is selected from numeric bar codes in
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 (single digit numbers must always be preceded by a leading
zero). In case of an error, or to change the selection, scan
Any Length - This option allows the scanner to decode D 2 of 5 symbols containing any number of characters
within the scanner capability.
Due to the construction of the D 2 of 5 symbology, it is possible for a scan line covering only
NOTE
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, it is recommended that specific lengths
(D 2 of 5 - One Discrete Length - Two Discrete Lengths) be selected for D 2 of 5 applications.
