General Description
In the event that the machine needs more than 4 denominations to be recognised
but the host machine cannot take advantage of the serial communication method
then the NV10 USB/+ can be set to give a binary pattern output on the four parallel
output pins. If the NV10 USB+ 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.
Caution!
Binary is an unsecure interface and
should not be used for new
developments!
