Decoded (Internal) Scanners
RSS Code (Reduced Space Symbology)
Set Length L1 and Set Length L2
Lengths for “Discrete 2 of 5” can be set for Any length, Length within a range, One discrete
length or Two discrete lengths. The length of a code refers to the number of characters (i.e.,
human readable characters), including check digit(s).
Double-tapping on this parameter displays a dialog box labelled Set Code Lengths where
you can define the code length that will be recognized by your scanner.
Choosing One discrete length allows you to decode only those bar codes of a specified
length. Choosing Two discrete lengths allows you to specify two lengths of bar codes that
may be decoded. Length within a range allows you to decode any bar code with a length that
falls within a specified range (e.g. between 10 and 15 characters). The minimum and
maximum values for the range are 1 and 12, respectively.

C.2.16 RSS Code (Reduced Space Symbology)
Enable
Setting any of these parameters to on enables “2D RSS Code” scanning capability.
Enable RSS-14 (Reduced Space Symbology)
RSS-14 code can be either purely linear or split in half with one half stacked on top of the
other half. Stacking the code reduces the bar code length, and providing the nominal height
of the code is maintained, it can be omni-directionally scanned.
Enable RSS Limited
“RSS-Limited” is restricted, in that it can only encode 14 digit GTINs (global trade item
number) that begin with either a 0 or a 1. It is not stackable and is not designed to be read
omni-directionally.
Enable RSS Expanded
“RSS Expanded” uses the same application identifiers as UCC/EAN-128 codes but it can be
split into sections and stacked several rows high, reducing the length of the symbol, while
increasing the capacity of data that can be stored. “RSS Expanded” code can be omni-
directionally scanned.
