Preferred Symbology
The engine 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 engine in a retail setting to read U.P.C. sym-
bols, 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.
Preferred Symbology classifies each symbology as high priority , low priority ,
or as an unspecified type . When a low priority symbology is presented, the
engine ignores it for a set period of time (see Preferred Symbology Time-out on
page 3-12) while it searches for the high priority symbology. If a high priority
symbology is located during this period, then that data is read immediately.
If the time-out period expires before a high priority symbology is read, the
engine will read any bar code in its view (low priority or unspecified). If there is
no bar code in the engine’s view after the time-out period expires, then no data
is reported.
Scan a bar code below to enable or disable Preferred Symbology. Default =
Preferred Symbology Off.
High Priority Symbology
To specify the high priority symbology, scan the High Priority Symbology
bar code below. On the
Symbology Chart on page A-1, find the symbology
you want to set as high priority. Locate the Hex value for that symbology
and scan the 2 digit hex value from the Programming Chart (inside back
cover). Scan
Save to save your selection.
