What is this? And How do I use it?

[alphasqorner]

I kno this is at least a counter.  Is it a coin counter?  And how do I use it?  It came with my used coin door and it seems that it's only connection is a power connection (a red and black wire, much like from a pc power supply).  Is there a way i can make this work with an IPAC?  thanks for any and all answers!

Yes, that is a coin counter (a.k.a. meter). These are for monentary duty and require a pulse to operate. The voltage should be printed on it somewhere and should say something like 6vdc, 12vdc, etc. Since it has a red and black wire coming out of it that signifies it's usually a DC voltage unit and there is an internal diode. I think yours is either made by Kessler-Ellis Products (www.kep.com) or Eaton Durant (www.durant.com)

There was some discussion a while back about getting one of these to work, but since it's not integral to the games actually working, not much, if anything, was done about it.  Likely if you wanted to get it working you could do so with a relay from the coin switch.

I have one wired up on my cab I'll check the wiring tonight when I get home as it was already wired up when I bought my cab. Later.

Wiring one to an existing cab should be easy.  It's wiring one to a MAME cab that was giving us problems.

JAMMA games generally have support for coin counting meters already built in. Couldn't say for MAME, though.

This might work if your cabinet is mame only and you want the coin counter to work. Add a second credit switch for the coin counter. Use longer screws and washers for spacers. Connect the second trip wire to the first credit switches trip wire. So when a coin is dropped the first switch posts a credit. And the second one will give the coin counter a quick pulse of 12v DC. Maybe this quick mock-up pic might help. Also rember to bend the first trip wire out of the way of the now longer screw.

Oh, i see.  But now my question is, how would I wire it all up?  The counter only accepts power so the switch would need to send it that 12v pulse so that switch would also need to be connected to some power source.  Being a newb electrical wiring, I have no idea how to go about that.

 Thanks for all comments btw!

On a JAMMA cabinet the coin counter meter would hookup this way:

The red lead goes to the power supply voltage source depending on the meter's stamped voltage. In other words if you have a 12 volt meter then the rd lead goes to the +12 volt terminal on the power supply. The black lead goes the either pin 8 of the Jamma connector ("coin counter one" which is the one most often used) or pin J ("coin counter two") and that's all there is to it!

If you had a 6 volt or 5 volt meter the the red lead would go to the 5 volt terminal on the power supply.
