StellarX:
What's the best way to wire up your control panel?
I am using the ipac and wired all the controls up fine, but getting all the ground wires together was agrivating and i don't think i did it right. I just twisted all the ground wires together at a central point, except for the coin slots, which i twisted together and put in the other ground slot. Everything works great but everynow and then the whole thing just screws up and it's easily fixed by unplugging and plugging the coin slot wires and grounds in.

Also, when i test the coin slot in some games, it 'sticks'. I've tried changing the wires, the only thing i haven't tried is a new wiring method. I've heard about using a wiring block or something. Should I do that to get the best performance?

Zipper:
'Daisy chain' the grounds of your controls. No need to have 2 wires coming from each microswitch.
Just make sure all the grounds are connected together. E.g. connect ground of button 1 to ground of button 2 to ground of button 3 etc. etc.
You only need the N/O wire coming directly from the microswitches.

I've taken this example from the i-pac website (I hope Andy doesn't mind!!):


See how the grounds  chain from 1 microswitch to the next...

hope this cleans up the birds nest of wires you must have!

JustMichael:
All I did was daisychain the grounds.  One wire goes from the ground on the I-PAC to the COM tab on a switch, then from that tab to the COM tab on another switch, then from that tab to the COM tab on another switch, etc. (until they are all done), then a wire from the last COM tab back to the  ground on the I-PAC.  The second connection to ground just make the wiring a little more fault tolerant.  You can have one break and everything will still work.  Also crimp .187" female quick disconnects onto the wires for connecting them to the switches (coin switches may need .250" quick disconnects).  To daisychain using quick disconnects, insert the wire going to this switch and also insert the wire going to the next switch and then crimp the quick disconnect onto both wires.

RacerX:
It's very difficult to say what the problem is without seeing it, but from what you said, it sounds like something isn't right with the coin slot wiring.  I would suggest double checking what you did there.

I did basically the same thing as you described, and mine works perfectly.  Although I did use a terminal block.  I ran all of my grounds to one central point and connected them, then ran a wire from there to the ground post on my terminal block, then ran a wire from the ground post on the terminal block to the ground on my encoder.

darkmanx:
they also sell a little 3-way combiner type thing if you dont like twisting them together. its a crimp connecter in a "Y" shape. just put one wire in each and clamp em down.  ;D

:i have only seen these at true value, they dont seem to be too common.
