Binary
General Decription
If the host machine needs more than 4 denominations to be recognised but the host machine cannot take
advantage of the serial communication method, then the BV30 can be set to give a binary pattern output on the
four parallel output pins. If the BV30 is set to Binary, it will issue the vend signals as a binary pattern on the parallel
outputs for 100 ± 3 ms. In this way a maximum of 15 different notes can be accepted and 4 notes individually
inhibited.
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 ± 3 ms. Pulses outside these limits will be rejected as a precaution
against false triggering due to noise.
For example, if a note programmed on channel 3 is credited Vend 1 (2
0
= 1 decimal) and Vend 2 (2
1
= 2 decimal) will
be active low for 100 ± 3 ms.
