Preferred Symbology

The scanner 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 scanner in a retail setting to read U.P.C. 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 Sym-
bology to specify that the PDF417 symbol be read instead of the Code 39.
Preferred Symbology classifies each symbology as high priority, low priority, or as an unspecified type. When a low priority
symbology is presented, the scanner ignores it for a set period of time (see
it searches for the high priority symbology. If a high priority symbology is located during this period, then that data is read imme-
diately.
If the time-out period expires before a high priority symbology is read, the scanner will read any bar code in its view (low priority
or unspecified). If there is no bar code in the scanner's view after the time-out period expires, then no data is reported.
Note: A low priority symbol must be centered on the aiming pattern to be read.
