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
: Channels (1 to 4) have their own individual inhibit input to allow the host machine
to refuse specified values of 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.
Note
: Channels higher than four cannot be individually inhibited, but will be globally inhibited if
inhibits 1 to 4 are inhibited.
If all four inhibits are high simultaneously then the NV10will not read in any notes. 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.
7.3: Binary Output
To use binary output DIP switches 3 & 4 must both be up and the BIN option of the interface
firmware must be loaded into the NV10.
In the event that the machine needs more than 4 notes to be recognised, but the host machine
cannot take advantage of the serial communication methods then the NV10 can be set to give a
binary pattern output on the four parallel output pins.
If the NV10 is set to binary mode it will issue the vend signals as a binary pattern on the parallel
outputs for 100 + 3ms. In this way a maximum of 15 different notes can be accepted and 4 notes
individually inhibited.
Vend Signals
(Pins 1 to 4). The four channels have their own individual outputs. If a note is
recognised then the binary representation of the channel number will be pulled low for 100 + 3ms.
Pulses outside these limits will 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). 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 on pin 10,
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 NV8 will go out of service for 45 seconds
.
Inhibit Operation
: Channels (1 to 4) have their individual 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.
Note:
Channels higher than four cannot be individually inhibited, but will be globally inhibited if
inhibits 1 to 4 are inhibited.
If all four inhibits are high simultaneously the NV10 will not read notes. All 4 inhibits connected
together create a 'global' inhibit. This way the NV10 may be brought in and out of operation by the
host machine.
