9.5 APPENDIX E – ESCROW CONTROL
The BV100 has a single note escrow facility (pin 10) used in Parallel and Binary modes.
This allows the Validator to hold onto the note once accepted, and then only stack the
note in the cash box when the host machine confirms that the Vend operation has been
completed. If no confirmation of the Vend is received then the note will be returned to
the customer after 30 seconds, (see Figure 11).
Figure 11 - Escrow Timing Diagram for Parallel Vends
If the host machine itself aborts the transaction by setting the corresponding inhibit
input high, the note is returned immediately. The sequence of operations is as follows:
· Pin 10 held low awaiting note insertion.
· Note inserted. Validator issues a 100 ms 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 100 ms pulse on the appropriate channel after pin 10 going
high to indicate final acceptance of the note. If the signal has not been received within
30 seconds it indicates the customer has forcibly retrieved the note and the vend will 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 BV100 during the
30 second interval, the BV100 will go out of service for 45 seconds.
