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.
Set lengths for D 2 of 5 to any length, one or two discrete lengths, or lengths within a specific range.

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.
