Discrete 2 of 5 (DTF)
Enable/Disable Discrete 2 of 5
Parameter # 05h
To enable or disable Discrete 2 of 5, scan the appropriate bar code below.
Set Lengths for Discrete 2 of 5
Parameter # L1 = 14h, L2 = 15h
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.
• 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 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 . To correct an error or to change the
selection, scan Cancel on page D-4.
• 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 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 .
To correct an error or to change the selection, scan Cancel on page D-4 .
• 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 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 (single digit numbers
must always be preceded by a leading zero). To correct an error or change the selection, scan Cancel on page D-4 .
• Any Length - Scan this option to decode D 2 of 5 symbols containing any number of characters within the digital scanner
capability.
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 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.
