11.7 Escrow Control
The NV9USB+ has a single note escrow facility. This allows the validator to hold
onto the note once validated, and then only stack the note into a cashbox 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 user after
30 seconds. If the host machine itself aborts the transaction by setting the
corresponding inhibit input high, the note is returned immediately. The sequence of
operation is as follows:
