12 - 48 DS8178 Digital Scanner Product Reference Guide
Discrete 2 of 5 (DTF)
Enable/Disable Discrete 2 of 5
Parameter # 5 (SSI # 05h)
To enable or disable Discrete 2 of 5, scan the appropriate bar code below.
Set Lengths for Discrete 2 of 5
Parameter # L1 = 20 (SSI # 14h), L2 = 21 (SSI # 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. The range for Discrete 2 of 5 lengths is 1 - 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 Appendix G, 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 H-1.
•
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 G, 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, then scan 0, 2, 1, and then 4. To correct an error or to change the selection, scan
Cancel on page H-1.
•
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 G, 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 Cancel on page H-1.
•
Any Length - Scan this option to decode D 2 of 5 symbols containing any number of characters within the
digital scanner 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.
