7: Machine Interface: Protocols
To select the required interface, the DIPswitches on the side of NV10 need to be set accordingly:
7.1:Parallel input and output
To use parallel outputs DIPswitches 3 and 4 must be set down.
Vend Signals: (Pins 1 to 4). The four channels have their own individual outputs. If a note is
recognised then the relevant channel line is set low for 100 + 3 milliseconds. Pulses outside these
limits should be rejected as a precaution against false triggering due to noise.
Busy Output: (Pin 9). This is a general-purpose busy signal. It is active low while the NV10 is in
operation.
Escrow Control (Pin 10) - Parallel mode : The NV10 uses a single note escrow facility in this mode
(see Appendix D ): 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 confirmation of the Vend is not received the note will be returned to the customer after
30 seconds.
If the host machine aborts the transaction by setting the corresponding inhibit input high, the note is
returned immediately.
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. Setting all the inhibits high will cause a note
reject.
In the event of a note being forcibly removed from the mouth of the NV10 during the 30 second
interval, the NV10 will go out of service for 45 seconds.
Inhibit Operation
Each channel (1 to 4) has its own inhibit input to allow the host machine to refuse specified notes. To
inhibit a channel, the relevant inhibit input must be held high. To enable a channel the corresponding
inhibits must be latched low so that notes may be accepted.
If all four inhibits are high simultaneously then the NV10 will not read in any notes. In this mode, if a
note is inserted the motor will run in reverse preventing the insertion of a note and the bezel will not
illuminate.
All four inhibits may be connected together to create a 'global' inhibit. In this way the NV10 may be
brought in and out of operation by the host machine.
7.2:Pulse Stream Output
To use pulse stream output for acceptance of up to 16 channel / note acceptance, DIP switch 3 must
be down and DIP switch 4 must be up.
Vend Signal (Pins 1): When a note is recognised vend 1 will pulse a pre set number times, the
number of pulses and the timing is set in the NV10 currency manager program (and set to default
values with supplied dataset).
The number of pulses is multiplied by a factor of four for USA Dollar datasets, depending on the
position of switch 2. If the switch is down then the number of pulses is as programmed in the dataset
output. If the switch is up then four times this number of pulses is output.
Busy Output : (Pin 9). This is a general-purpose busy signal. It is active low while the NV10 is in
operation.
Escrow Control : (pin 10). The NV10 uses a single note escrow facility in this mode (see Appendix
D ): 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
confirmation of the Vend is not received the note will be returned to the customer after 30 seconds.
If the host machine aborts the transaction by setting the corresponding inhibit input high, the note is
returned immediately.
