5 MACHINE INTERFACE: PROTOCOLS
5.1 PARALLEL INPUT AND OUTPUT:
To use Parallel Output for 4-note/channel acceptance, the parallel interface must be
programmed into the validator via the Configuration Cards (See Appendix D –
Configuration Cards) or via the ITL BNV Currency Manager program. In parallel mode the
BV20 will issue a 100ms (±3%) active LOW pulse on the relevant vend line. A maximum of
4 channels can be used.
Connections:
Pin Name Type Description
1 Vend 1 Output Channel 1 credit, 100ms (±3%) active LOW pulse.
2 Vend 2 Output Channel 2 credit, 100ms (±3%) active LOW pulse.
3 Vend 3 Output Channel 3 credit, 100ms (±3%) active LOW pulse.
4 Vend 4 Output Channel 4 credit, 100ms (±3%) active LOW pulse.
5 Inhibit 1 Input Inhibit channel 1 by holding this pin HIGH, hold LOW to enable.
6 Inhibit 2 Input Inhibit channel 2 by holding this pin HIGH, hold LOW to enable.
7 Inhibit 3 Input Inhibit channel 3 by holding this pin HIGH, hold LOW to enable.
8 Inhibit 4 Input Inhibit channel 4 by holding this pin HIGH, hold LOW to enable.
9 Busy Output Active LOW when the BV20 is transporting, reading or stacking
a note
10 Escrow Input Enable the escrow function by holding LOW (See Appendix B –
Escrow Control)

Table 7 - 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.
