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 nume ric 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 Discre te 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 de co de o nly those D 2 of 5 symbols cont ainin g either 2 or 14 ch ara cte rs, 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 Leng ths
Length Within Range - This option allows the scanner to decode a D 2 of 5 symbol with a specific length
range. The length ra nge is sele cted fr om n umeric bar co de s 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 Ra nge.
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 op tion 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.
