Hope all is well arcade enthusiasts. I am building another cabinet and will be using a groovy game gear usb game wiz joystick encoder board.
I traditionally have used a simple coin mech for credits. This time I am going to use a modern multi-coin mech.
Just wondering if a modern coin mech will work a USB game ziz board? In the past I have simpler mechanical coin mechs with mechanical Normally Open switch.
I haven’t seen too much information about these modern coin mechs. What makes it appealing to me is that it takes a multitude of coins. I’d like to be able to use nickels and quarters to trigger credits. The coin mech requires 12 vdc and also needs to learn the coins. Once a coin successfully passes through its shute it sends a pulse or several pulses depending on the coin. I’d like to have a nickel add one credit and a quarter add 5.
Here is a link to the moden coin mechanism I am planning on using…

Any reply is greatly appreciated. Thanks in advance and thanks for this great resource of a forum.

Greetings, michelevit!
I assume that if each pulse can be interpreted as a keystroke/button push, it would work. The only thing I would worry about is current. You might need to put some diodes in the somewhere in your setup.

Here is some info from Ultimarc re the coin acceptor. Since it runs off of 12V it is essential to add a 5V zener diode to control the output pulse so it does not damage an ipac. In your case a keywiz which also runs off of 5V.

Coin Mech setup steps:
Set the slot height plate to the correct coin size. Note that for larger coins, this plate is best removed to avoid bearing against the coin door.
Clip the correct sample coin into the spring-loaded clip, in place of the dummy plastic coin.
Leave the switches unchanged for most applications
Connections are as follows (see diagram above):
Pin 1 connects to a 12 volt supply. This can be from a JAMMA power supply or a PC disk drive connector (yellow wire).
Pin 2 connects to the I-PAC coin 1 input.
Pin 3 connects to GND on the I-PAC
The Zener diode connects between pins 2 and 3 on the coin mech plug. It is possible to push the wire ends of the diode into the plug connector housing.Note the "line" end of the diode must go to pin 2.
The coin signal is normally a 12 volt signal. If using with devices which expect a 5 volt signal it is VITAL to connect the supplied Zener Diode as shown otherwise the device you are connecting to will be damaged.

my olny question here
is it SINGLE CHANNEL OUTPUT OR TRIPPLE?

Single output (only 1 zener) multi pulse.

I was able to wire up the multicoin mech to my usb groovy game gear board. i did use the recommended diode as illustrated above. A whopping 79 cents from my local electronics shop.
Works great. I highly recommend it to anyone looking for a coin mech. What’s really nice is that you can assign different values of credits depending on what type of coin you insert. I have quarters registering 1 credit to maintain authenticity and nickels and dimes registering a whopping 10 credits as an Easter egg gifted from King Candy himself. You can allow 50 credits max per coin which I might implement for an essential free play once I find a unique token to use.
It does require 12 vdc which I tapped from the pc power supply yellow wire. Programming is done by accessing admin buttons on the back of the mech. I’m curious on how the mech distinguishes different coins instantaneously with such accuracy. If a coin is not recognized, it rolls down to the coin return slot.
Thanks for the advice and the great forums.
