Decode Search Mode
There are three selectable decode (scanning) modes:
Full Omnidirectional - Searches for bar code features beginning at the center
of an image, and searches to the image’s limits. This mode reads all
symbologies (including OCR), in any orientation. The Full Omnidirectional
search is very thorough which may slow performance time.
Note: This search mode is the default setting.
Quick Omnidirectional - This is an abbreviated search for bar code features
around the center region of an image. This mode quickly reads all symbologies
in any orientation. The Quick Omnidirectional mode may miss some off-center
symbols, as well as larger Data Matrix and QR Code symbols.
Advanced Linear Decoding - Performs quick horizontal linear scans in a center
band of the image. This mode is not omnidirectional, but does quickly read linear
and stacked bar codes. Advanced Linear Decoding cannot read 2D, OCR, or
Postal symbols.
Preferred Symbology
Note: This selection applies to the 4600r only. It does not apply to OCR.
The 4600r can be programmed to specify one symbology as a higher priority over
other symbologies in situations where both bar code symbologies appear on the
same label, but the lower priority symbology cannot be disabled.
For example, you may be using the imager in a retail setting to read UPC
symbols, but have occasional need to read a code on a drivers license. Since
some licenses have a Code 39 symbol as well as the PDF417 symbol, you can
use Preferred Symbology to specify that the PDF417 symbol be read instead of
the Code 39.
