Scanning Composite Bar Codes - Symbol Cyclone M2000 Series Product Reference Manual

Scanning Composite Bar Codes

Composite Code is a combination of a 1D symbol (RSS, UPC/EAN or UPC/EAN-128) and
a 2D symbol (CC-A, CC-B or CC-C).
When scanning a barcode:
• Keep the scan pattern parallel to the 2D symbol's rows.
• Hold the scanner as still as possible.
• Hold the scanner at an angle which does not cause specular reflection (see
Specular Reflection
• Hold the scanner close for small symbols, and farther away for large symbols.
Practice shows what works.
• When using the single scan line pattern, aim the scan line at the middle of the 2D
portion. The scan pattern will open up to an optimized raster pattern and decode
both the 2D and 1D portion of the Composite Code.
Aim the single scan line at the center of
the 2D portion
Note: It is not recommended to scan Composite Codes in the hands-free
(on-counter) mode with a single scan line pattern. This will produce
multiple reads of the bar code. To avoid this, scan the Composite
Code in handheld mode.
Composite Codes cannot be read with the Cyclone,
Omnidirectional, or Semi-omnidirectional scan patterns.
The scanner allows the user to choose the beep mode to indicate a successful decode.
Three options are available:
• Single Beep after both 1D and 2D symbols are decoded; the scanner emits a short,
high-tone beep.
• Beep as each code type is decoded; the first decode beep is a short high tone beep
if the 2D portion is scanned first, or a short low tone beep if the 1D portion is
on page 2-7).
Raster pattern will expand to decode
