i'm a service technician dealing with tons of these machines.So I scratched my head almost all night and I couldn't make the acceptors to work.
I can tell you how to configure ICT A6/V6/A7/V7 acceptors, I know nothing of how to configure any other acceptor that may be in there.
if you remove the acceptor from its mount (4 screws) and look at the front, you can slide the panel above the bezel up, away from the bezel about 1/2 inch... and pull it towards you to pull it off.
in there is a 4 switch DIP switch. you will want to configure the switches from 1-4 as on, on, off, off (sw1 and sw2 on) reinstall cover.
then the larger 8 position switch on the side should have them all off except 6 and 7 and the smaller 4 position switch bank should have 1 off, 2 off... then 3 and 4 will determine the pulse length of each dollar pulse which will depend on your controllers ability to read low pulses and how it rejects invalid pulses.
see http://www.ictgroup.com.tw/download/Dip%20Switch/A6.V6-USD4%E8%AA%AA%E6%98%8E%E6%9B%B8SWAUS470-R.pdf for dip switch settings for pulse timings
power on the acceptor and it will be automatically enabled in stand alone mode with pulse output. you will have to modify your power/data cable with the appropriate wires to use pulse mode. check in the A6/V6 manuals for pinouts of the interface for where you should have the common and pulse wires. these wires will be where you connect them to your interface to get "credits" (microcontroller or whatever) the common and pulse wires will be "connected together" for each dollar inserted. (so a $5 bill pulses 5 times, a $1 pulses once, etc.)
EDIT: the programmer you would need would be an FP-001 and you would also need test/calibration cards to calibrate the acceptor after programming, which you won't get unless you bought a kit or bought them separately. i haven't purchased the current FP-004, as i have nothing additional it supports, so i'm no help there. the only reason to re-program or have the tool to begin with is if you need support for newly released bills or you've repaired the optic scanner and need to recalibrate it.... and it's not worth it to buy unless you have a bunch of them (like more than 20)... just pay a local company to do it for you if you just have 1 or 2. (search for game operators or vendors... or the like in your area and ask... we re-program units for 20 bucks each or in bulk by the shops hour rate.) but honestly if it doesn't need reprogramming, there is no advantage to doing it.
hope this helps
I followed all of your instructions but no pulses are detected.
Now I few years back, I did play with a pulse bill acceptor, by using a 5v Arduino relay, it was simple. 5v to the relay, ground to the relay, and the n.o. from the bill acceptor to the in of the relay. Also the ground for the acceptor was together with the relay ground. Doing that , I had the relay outputs to a keyboard encoder and all worked fine.
I've tried to follow the same here, but I get nothing everytime I inset a bill.
The relay won't detect the pulse.
Then I tried adding 5v to the input 1 on the bill acceptor to no good.
Tried different mseconds outputs but nothing seems to work.
I even set 20 pulses per dollar in hopes of seeing something but no go.
I even added the 5v to the n.o. output on the receptor but nothing.happened. At this point I'm not sure what else to do.
My goal is to send a signal to a keyboard encoder as I did in the past. Any advice will be surely appreciated. Thanks.
