Coin Counter

[simplesi]

Just wondering if someone could help me fix my coin counter. I picked up an old shell of a cocktail cab (Taito). There was not much inside apart from the service button and the coin counter. All the harness, pcbc, etc were taken out.

I am installing a multiboard with a jamma harness and wanted to link up the coin counter. I haven't a clue what's what. Any help would be greatly appreciated.

Here are some pics below:

What does the yellow wire connect to and the bluish one? Is one connected to the Counter 1 on Pin 8 on the harness and the other the 5V? How does the board know that you have put a coin in? It's all magic to me. Do I have to ground it? So many questions...

sorry, i have been here a couple of times, and i can see you have posted the same on UkVAC - with a bit more help....

Cheers guys. 

Has anyone got a Taito Cocktail that could help with?

Can anyone help... Ully... Etienne... Muddy...

i interpreted michael's posting that you've put up the same thread on UK-VAC and got help there - am i mistaken?

I would love to help, i just dont know nothing about them.

i know it needs a puls, the question is how many volts, and AC or DC...

You can try to puls it by connecting 5 volts dc for example.
If nothing happens, try 5 volts ac, if still not happens nothing , increase the voltage 

but dont hold me responsible if it burns out

@Ully... not really got the answer from UKVAC. Need a little more info. Thanks though.

@Etienne... I tried using the 5V DC from the mian power supply, connected to the ground and I can get the counter to rotate. The issue I have is do I need to have a diode (resistor?) so that when I connect to the PCB I don't sned 5V into the board and screw things up! Would just be my luck.

It never hurts to add a diode to protect the board..

What kind of multi board are you connecting ? Does it actually have any output to spend out the Coin pulse ?

[simplesi]

Hi,

It's a 60in1. It says in the instructions that it can.

Are you able to help Level42?

Got some schematics or manual of the 60in1 ?

The diode should not be in series but parallel over the coin-counter. It's function is to "extinguish" (as we call it) any peak voltages coming back from the coin counter into the game PCB.

The most coin counters I know require a higher voltage than 5V (about 10 IIRC).

Checked the 60in1 manual here http://www.jammaboards.com/arcade_manuals/60-in-1_iCade_Classic_Arcade_Manual_Online.pdf

but it's not really helpful. It says pin 8 on the parts side is Coin meter P1. I +GUESS+ that that will be the positive pulse to trigger the coin meter. You should measure it with a DVM to see if I'm correct and what voltage it is, but it will probably hard to see since it's a very short pulse.

IF I am correct with the assumption above, you would hook up the + of the coin meter to pin 8 and the - to a GND connection.

Again, you MUST put a diode in parallel over the coin meter connectors (NOT at the PCB side, it won't help much there).

The cathode has to be at the + side and the anode on the - side of course (else it will short circuit of course).

Here is how to hook it up IN THEORY !!!!
