No Bar Code Message
No Bar Code Status
No Bar Code Message
Definition: When enabled, sends a message to the host whenever an object is
detected but no bar code label is detected. See “Transition Counter
Threshold” on page 6-10.
The No Bar Code output is tied to the transition counter. If during a
read cycle no symbol is decoded and the required setting for the Tran-
sition Sample Threshold is NOT met, a No Bar Code message will be
sent to the host. See “Output Message Flow” on page 8-4.
Usage: Useful in determining if an object has an attached bar code label.
