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 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 5-4). The hex
code for the No Read symbol is 9C.
Video Reverse
Video Reverse is used to allow the image 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.
