I have a Mars MS112 coin mech connected to a CoinWorld credit board. Am i right in thinking that the terminal marked ' Coin Pulse Output' on the credit board should be connected to the 'COIN 1' terminal on the I-PAC? I have done this but mame does not register the credit. I have also tried connect the 'COIN 1' input on the I-PAC to the terminal labeled 'S10 Coin Switch normally open (Coin input 5)' but this still did not register a credit, there is one other terminal on the credit board labeled 'Coin Mech Lamp & S10 Coin Switch Common (+12 Volts)' but i didnt think i should connect this up to the I-PAC as it suggests that is has a +12 volt current??
I am at a bit of a loss as to why i cannot get this to work, the Coin mech itself must be a electrical one as there is no cheery switch or any switch on the coin mech itself to connect up to the I-PAC. I will later connect a normal push button switch up to the 'COIN 1' input and see if that registers a credit just to make sure its not the I-PAC itself. Has anybody any suggestion as to what im doing wrong???

Anyone?

The first point is that tis type of mech needs a power supply. Have you got a 12 volt supply connected to it?
Before connecting the coin signal wire to the I-PAC, check the voltage on it. It might be sitting at 12 volts and drop down to zero momentarily when a coin is inseretd. If it is at 12 volts, don't connect it to the I-PAC. You would need to use a Zener diode to ensure the voltage on the line is capped at 5.

Yeah the credit board itself has has a 12 volt supply doing to it, i explain how i have it wired up. A ribbion cable connect the coin mech to the credit board, on the credit board i have attach (via srew terminals) a +12 volt in, 0 volts in, and Coin pulse output, which i originally connect up to the I-PAC. Also connect to the credit board is +12 volts to meter, and 0 volts to meter.

On my machine, I run the coin pulse wire from the credit board into the 1PCoin input on the ipac then I run a ground wire from the credit board into the ground input on the ipac.
I used a multimeter to find which of the other wires from the credit board made a circuit when a coin was dropped through. I basically had my housemate dropping coins in whilst I checked to see if the multimeter registered a reading...
