7: Machine Interfaces: Protocols
To select the required interface, the DIPswitches on top of the NV9 need to be set accordingly:
7.1:Parallel input and output:
To use parallel output for 4 notes / channel acceptance, 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 a period of 100 ± 3ms. 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 NV9 is in operation.
Escrow Control): (pin 10). - Parallel mode : The NV9 uses a single note escrow facility in this mode (see
Appendix B ). 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 NV9 during the 30 second interval, the
NV9 will go out of service for 45 seconds.
Inhibit Operation: Channel 1 to 4 have their 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 inhibit must be latched low so that notes may be accepted.
If all four inhibits are high simultaneously then the NV9 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 NV9 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, DIPswitch 3 must be down
and DIPswitch 4 must be up.
Vend Signal: (Pins 1) When a note is recognised vend 1 will pulse a pre set number of times, the number of
pulses and the timing is set in the ITL BNV validator 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 NV9 is in operation.
Escrow Control: (Pin 10). The NV9 uses a single note escrow facility in this mode (see Appendix B ). 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 NV9 during the 30 second interval, the
NV9 will go out of service for 45 seconds.
