- Parallel and Binary Pin Description
Vend signals: (pins 1 to 4) The four channels have their own individual outputs. If a note is
recognised then the relevant Vend line is set low for a period of 100ms ± 3%. Pulses
outside these limits should be rejected as a precaution against false triggering.
Inhibit inputs: (Pins 5 – 8) Channels 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 NV200 will be disabled. In this state
the bezel will not illuminate and if a note is inserted the motor will run in reverse
preventing the insertion of the note.
All four inhibits may be connected together to create a 'global' inhibit. In this way the
NV200 may be brought in and out of operation by the host machine.
Busy Output: (Pin 9). This is a general-purpose busy signal. It is active low while the
NV200 is in operation.
Escrow Control: (Pin 10) Hold this pin Low to enable the single note escrow function.
