The sequence of operations is as follows:
•
Pin 10 held low awaiting note insertion.
•
Note inserted. Validator issues a 100ms pulse on the appropriate channel.
•
The host machine initiates vend process.
•
The host machine sets Pin 10 high to indicate that it wants the note. If this is
not done within 30 seconds the Validator will return the note.
•
The Validator issues a 100ms pulse on the appropriate channel after Pin 10
going high to indicate final acceptance of the note.
NOTE: If the signal has not been received within 30 seconds it indicates the customer
has forcibly retrieved the note and the vend must be aborted.
•
The vend process is completed.
•
The host machine sets Pin 10 low in expectation of the next vend.
The host machine can force the return of the note to the customer by setting the inhibit
line high, at any time before the end of the 30 second time-out. For channels above 4,
setting all the inhibits high will cause a note reject.
In the event of a note being forcibly removed from the mouth of the NV200 during the
30-second interval, the NV200 will go out of service for 45 seconds.
