N4680 2D Decoded Scan Engine User Guide 57
No Read
With No Read turned On, the scan engine notifies you if a code cannot be read. If
using an EZConfig-Scanning Tool Scan Data Window (see page 177), an “NR”
appears when a code cannot be read. If No Read is turned Off, the “NR” will not
appear. Default = Off.
If you want a different notation than “NR,” for example, “Error,” or “Bad Code,” you
can edit the output message (see Data Formatting beginning on page 5-65). The
hex code for the No Read symbol is 9C.
Video Reverse
Video Reverse is used to allow the scan engine to read bar codes that are inverted.
The Video Reverse Off bar code below is an example of this type of bar code. Scan
Video Reverse Only to read only inverted bar codes. Scan Video Reverse and
Standard Bar Codes to read both types of codes.
Note: After scanning Video Reverse Only, menu bar codes cannot be read. You must scan
Video Reverse Off or Video Reverse and Standard Bar Codes in order to read menu
bar codes.
Note: Images downloaded from the unit are not reversed. This is a setting for decoding only
Video Reverse and Standard
Bar Codes
