hey guys

i want to connect my 12 volt coin mech to the jpac. one wire goes to the gameboard powersupply 12volt but that is now disconnected, so is it safe to connect it directly to my pc taking 12 volt from that?

connect to peripheral connect yellow pin only?

just asking to make sure, rather safe than sorry.

You need to connect what is called a dry contact to your jpac.  It has no voltages  on it and just completes the circuit between ground and your jpac pin for coin input.   A diagram of what outputs your mech has will help determine what pins to connect.  If you connect the 12 v to a jpac input you will damage the jpac.  It does not matter if the jpac gets 12V from the computer or the arcade supply it will still destroy the input on the jpac.   A jpac senses its inputs by taking 5V to GND.

any step by step on how todo this?
im also abit confused. cause if the coin mech uses 12 volt to power it and it does not get it how will it work?

The coin mech can be connected to 12V and ground but you have to know what contact to connect to your jpac.  As I said before you need the circuit diagram or contact list for your output pins from the coin mech.   No step by step unless you can provide the info for your coin mech.  ???
