Preferred Symbology; High Priority Symbology - Honeywell HH1800 User Manual

Preferred Symbology

The scanner can be programmed to specify one symbology as a higher priority over other
symbologies in situations where both barcode 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 driver 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 scanner ignores it for a set
period of time (see
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 scanner will read
any barcode in its view (low priority or unspecified). If there is no barcode 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.
