Composite
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.
Length Restriction
Refer to “Length Restriction” on page C-14 for details.
Add/Remove Data
Refer to “Add/Remove Data” on page C-14 for details.
C.2.18 Composite
A composite symbol includes multi-row 2D components making it compatible with linear
and area CCD scanners along with linear and rastering laser scanners. The options available
for this parameter represent multi-level components of a composite symbol.
Enable CC-C And Enable CC-AB
To activate these components, set the parameters to on.
Enable TLC-39
This composite component integrates MicroPDF417 with the linear code. Setting this pa-
rameter to on enables this parameter.
Important: To successfully read this type of bar code, the two types of symbologies
included in a composite bar code must be enabled. In addition, “Center Bar
Code Only” must be disabled (see page C-42).
