6.9.3 Inhibit Control
The Inhibits can be used to either enable or disable the acceptance of those
banknotes programmed on channels 1, 2, 3 and 4. The Inhibits are internally held
high and must be set to low (GND) to enable banknote acceptance. If no Inhibit is
set to low (GND) the Master Inhibit is set and the validator is disabled.
6.9.4 Escrow Control
The NV9 validator has a single note escrow facility. This allows the unit 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. Please refer to
Appendix 11.8 for timing diagram and further details.
6.9.5 Credit Hold Function
If this function is enabled, the validator will take the notes as normal but then wait
until the escrow line is toggled low/high before it will then give out the pulses per
denomination as set. After the pulses have been given, the validator will wait for
another low/high toggle until the full value of credit pulses are given.
For example, with a setting of 2 pulses per dollar, a five dollar bill will give 2 pulses
5 times.
A Typical use of this option would be for a Pool table with a game price of $1. You
could insert a $5 note and press a button that toggles the escrow line and releases
the pool balls, this would then allow you to play the first game. The Validator holds
onto the remaining credits until the game has finished and the button is pressed
again allowing the next game to begin, this continues until all the credits have been
used.
The busy line remains low throughout the whole process and the NV9USB+ remains
inhibited until all pulses are given.
6.9.6 IF15 Interface
The IF15 is an interface that allows serial SSP to be used in machines without the
need of updating the machine software. The IF15 is connected between the
NV9USB+ and the host machine. The IF15 communicates with the validator in serial
SSP which gives more security along the length of the cable. The IF15 should be
mounted close to the host machine control board where the IF15 converts to the
pulse connection.
