Multiple Symbols

When this programming selection is turned On, it allows you to read multiple symbols with a single pull of the scanner’s trigger. If you press and hold the trigger, aiming the scanner at a series of symbols, it reads unique symbols once, beeping (if turned on) for each read. The scanner attempts to find and decode new symbols as long as the trigger is pulled. When this programming selection is turned Off, the scanner will only read the symbol closest to the aiming beam.

With No Read turned On, the scanner sends an “NR” to the host if you pull and release the trigger without reading a code (e.g., bad bar code). 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 scanner to read bar codes that are inverted. The “Off” bar code below is an example of this type of bar code.

Note: If additional menuing is required, Video Reverse must be disabled to read the menu bar codes and then re-enabled after menuing is completed.
