The pinout is at the bottom of page 2.
According to the datasheet, your 5v relay should close when you apply at least 3.75v@53mA. (200mW)
That should work. :dunno

You are my saviour man... my own personal jesus christ lol
On way to work now though, will check it when I rotate back.
Hold thumbs.

Scott,
Can you get the datasheet for the 5 pin, 12v relay I have? (The one being used for the coin mech / encoder wiring)
Also, what does 'Min. Switching Load' mean? I see it should be minimum 5v.
When I check the pulse voltage, its only 4.5v? I'm no electronics engineer, but could this mean it is expecting a minimum of a 5v pulse?

The datasheet for your 12v relay is here. (Didn't find an english version.)
According to the datasheet, your 12v relay needs 8.4v to throw the switch.

Since the mech is putting out 4.5v, you'll need to use the 5v relay that will work with as little as 3.75v.
That's why I suggested several posts ago that you use the 5v relay instead of the 12v one that needs about 8.4v.

The relay contacts have a minimum load rating (5VDC, 10mA) to ensure that the voltage and current will break through any corrosion on the relay contacts.
The ZD should be providing enough power.
If you want to verify that, touch one lead from the ZD to COM and the other to NC.
If the button press registers, you're good to go. ;D

Ah, my deductive logic serves me well :) Scrumtrulescent!
I am slowly learning the ways of electronic wizardry lol
Perhaps one day, I shall take my rightful place as an honored member of the community...
and shed the tattered rags of noobosity forever!! :notworthy:
until that day, i shall continue to survive as a leech hanging from the balls of your collective intellectual prowess,
as a chinese man walking around in DARPA lol
Yours truly,
The infant

This thread is awesome. Lots of great information. I'll be sure to remember it as I click 'Submit' when ordering my next ipac.
Seriously though, I'm sure your wife would like to keep costs down, but if given the choice between spending $40 or losing her husband for cycle after cycle of troubleshooting, I'd think she might choose to spend the money. Hey, you prolly pay the sitter more than that just to go catch dinner and a movie. Time is money.
But, if its knowledge that you are seeking, carry on. You can make it repeatable for your future builds.

As mentioned before, it has now become more a matter of principle. a proof of concept really.
We know it's technically possible.
Also, once we get the first one working it would be a cinch to duplicate it and do it in 5 mins if the process was documented.
All you would need extra would be a $2 relay.
Think of it this way, usb encoder + coin mech + relay would set you back $22. You would only need the additional push buttons and arcade joystick. (How much is an ipac alone $45?)
You may think what I am doing is a waste of time, but I prefer to think of myself as the poorman 'cade builders robin hood lol
Cue the bryan adams.
Edit: I will try the ipac solution to compare, but I want to get this working first.
