I purchased a used over/under coin door w/ mechanism from a Dig Dug machine, and I was wondering how to wire it. I know how to wire the lights, and I thought I knew how to wire the micro switches, but there are 2 additional connections, they seem to go to a diode, one on each coin slot. I am wondering what those connections are for, and how to wire them.
Here is a picture, this isn't the same mech I have, but it has similar connections.

I know connection 1 goes to the lights, I am going to use the 12V from the PC power supply, and connection 2 goes to the micro switch, I was just going to connect the switch to my iPAC2, just like a regular button, but what is connection 3 for?

those are the coin lock out feature. When machine is OFF, and someone insert a coin, it won't accept it.
You can just remove it..... ;)

Cheeeeseman,
You asked the question before I could. I am getting to my coin door hopefully this weekend and having been trying to figure it all out. I was curious as to what those connections circled in red did. I know currently when I insert a coin it always gets rejected, which makes sense since there is no power. I figured these might need to be powered somehow in order to work.
So how does removing them allow them to work? Wouldn't they need to be cross connected to think that the machine is on?
I also have a question about another area of the coin mechanism. I circled it in yellow in the picture. It looks like some kind of switch that is closed when the door is closed? How does this need to be wired to allow the coin door to operate?

that one circled in yellow is the SLAM SWITCH.
When someone KICKS the coin door, it triggers that switch and RESETS the GAME.....This you can use with no problem with MAME.
The Coin Lock out and the SLAM switch is really not necessary for your HOME GAME SYSTEM.
You are not goin to KICK your MACHINE, and you aint going to insert COIN when its off or when you are in the MENU (FRONTEND). Totally useless for your HOME GAME.
The COIN LOCKOUT you won't get it to WORK cause of the FRONTEND INVOLVE and in plain MAME, you may need to make some sort of of a relay to turn the coin lockout once the selected game is launch thru SERIAl/LPT port.
-
That coin lockout would be an interesting project.
Be neat to not waste quarters in the front end.
-
Slam switch? Never heard of those, but an effective deterrent back in the day I bet; kick me and lose your f-ing game!
-
My door had that slam switch too. It has a weight on it so I could tell that's how it worked but didn't know what it was really for. I took it off.
-
So you can just not wire the Slam Swith and the Coin Lock Out and it will be fine?
I question this, because when I drop a quarter in now, with nothing powered, it always goes through and comes out in the coin return. I figured this is because there was no power going to the coin door, machine turned off, quarter falls through to return, makes sense.
I figured when the coin door was powered, not just lights, but power to the mechanisims, then the Coin Lock Outs would turn on, and be able to distiguish between a quarter and something else. Quarters going into the coin bucket and triggering a credit, everything else in the coin return.
I wasn't sure what type of power was needed for the Coin Lock Outs. If there is no power to them, won't they just continue to reject anything and never give credits?
-
Is it a magnet in there that if it has power it pulls something ot make the coins go trough? Can you move the switch manually to find out how the coins can go the proper path? I haven't hooked mine up yet so I'm just guessing....
-
Ive never dealt with the coin lock things, but from the posted pic, they look like solenoids or relay armatures.
If that pin going into the coin mech is on a movable arm near the round part of the lockout (probably a coil), try holding the arm in, see if it pulls the pin out of the mech. if so, try dropping a quarter in with the pin retracted.
If it works then all you will have to do is remove the lock out things.
Im thinking with power off, the coin is rejected, which makes sense in case the machine is unplugged or broke. The coil energized should pull the pin out of the mech and allow the mech to work as intended.
But I could be wrong.

I just reread the posts and looks like the nasty has already said the same thing, just a lot quicker..
DOH..

Yes take it out.

Normal behaviour

Got nothing to do what coins it goes in. It can't distinguish between diferent coins, thats the Coin Mechs job not the Coin Lock Out Coil.
I wasn't sure what type of power was needed for the Coin Lock Outs. If there is no power to them, won't they just continue to reject anything and never give credits?
Thats why you TAKE IT OUT. It is completely USELESS unless you want to make some changes in the MAME CODE to do what it supposed to do.
This is how you need to make it work.
1. After a GAME is selected, it turns ON (accepting coins)
2.When in the MENU (FRONTEND) it shuts off (returns coins when inserted).
Just remember, all this time your MACHINE is ON ! ! !
-
or if don't want to take it out, just have it POWERD UP when your machine is ON so it accepts coins even when your in the MENU, GAME, NES etc...... (using/Draining some juice of your PS/electricity). Sure it works, when machine if off, and some dumb dumb inserts a coin :P
What sort of power it needs, I dunno probably 12/24 vdc. Look at the back of the coil, it should say something.
-
Well I was able to successfully disable the coin lockout. Now the coin comparator works like a champ. Every once in a while a quarter will stick in the cradle on the right coin slot, I tried adjusting the magnet gap, but it didn't seem to help. It looks like only newer quarters (State Quarters) get caught, and only if inserted very lightly, however a simple tap to the coin door usually drops the quarter in.
