Multiple Symbols
When this programming selection is turned On , it allows you to read multiple
symbols with a single pull of the image scanner’s trigger. If you press and hold
the trigger, aiming the image scanner at a series of symbols, it reads unique
symbols once, beeping (if turned on) for each read. The image scanner attempts
to find and decode new symbols as long as the trigger is pulled. When this
programming selection is turned
Off , the image scanner will only read the symbol
closest to the aiming beam.
No Read
With No Read turned On , the image scanner sends an “NR” to the host if you pull
and release the trigger without reading a code (e.g., bad barcode). If No Read
is turned
Off , the “NR” will not be sent to the host.
If you want a different notation than “NR,” for example, “Error,” or “Bad Code,”
you can edit the output message using the
Data Formatter (page 5-5). The hex
code for the No Read symbol is 9C.
Video Reverse
Video Reverse is used to allow the image scanner to read barcodes that are
inverted. The “Off” barcode below is an example of this type of barcode.
Note: If additional menuing is required, Video Reverse must be disabled to read
the menu barcodes and then re-enabled after menuing is completed.
