NV10 Operations Manual 13
DIPswitch 2: Used to select/de-select the X4 Pulse Multiplier.
Down – Number of pulses are as programmed in the dataset.
Up – Number of pulses is multiplied by 4 (Useful for USD Datasets)
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). Hold this pin Low to enable the single note escrow function.
(See Appendix B).
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 causes
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: (Pins 5 – 8) Channels 1 to 4 have their own 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.
If all four inhibits are high simultaneously then the NV10 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.
Note: Channels higher than four cannot be individually inhibited, but will be globally
inhibited if inhibits 1 to 4 are inhibited.
6.3 BINARY OUTPUT – BIN
To use Binary mode DIPswitches 3 and 4 must be in the Up position to select ‘Special’
mode on the validator and the BIN option of the interface firmware must be loaded into
the NV10. (Dipswitch 2 is not functional in this mode)
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 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.
