Ipac2 Wiring Issues, Then Some Buttons Changed in Mame???
RoninEditor:
I don't even know how to properly title this so here's what my issue is, then I'm home free...
So, on my control panel, I have all of the buttons wired up, as well as two 'hidden' 1P/2P free play buttons. I left my coin door switches for last, just wanting to test the overall CP. So, that all worked perfectly, the pre-wired coindoors ready to be later connected to their micoswitches.
I originally tried to wire the 'free play' buttons together into the usual 1P Coin/2P Coin on the Ipac2; 1P freeplay with 1P physical coin slot, into the same Ipac terminal. Okay, so then I connected up the microswitches on the door, then restarted. The Ipac went numb, no light. I pull the PS2 cord then put it back in... it flashed a couple times then still nothing. Obviously, at that point, the variable was the coin door microswitches. I tried a couple restarts then the coin door microswitches "took over" and my freeplay ones went useless, basically, flip-flopping what was going on before... and I didn't move a single wire or redo anything into the Ipac.
With me so far? :)
So then today I divided up the wires that were combined, going into the 1P coin and 2P coin, each getting their own terminal... so two possible credit microswitches for 1P's credit (the coin door and the side button) and the same for 2P. So, I go into Mame today and now none of them work for a credit!!
Odd, right?
Everything matches up in WinPac (sp?) and I used the CP to 'type' and everything reads perfectly, ya know, like when putting in a coin, "5" shows up in a document. When I press my freeplay on the side, the letter pops up. And back in Mame, the coin slot actually read for a game I tested, but not for the rest.
Another weird thing is that my shifted buttons don't seem to read any more either, even though they're still mapped like I'd always had them.
I had to get to work (where I now, on lunch break) but I wanted to TAB through a pass-through keyboard, and see what defaults are now set for the credits, because everything else works fine.
But my overall question is, "how" does/did this happen? And, has anyone else seen something like this? I'm concerned about the Shifted buttons and getting these credits to read.
Always something when you think you're done! haha

Be careful of the voltage of your coin mech. When using Ultimarc's coin mech, you have to use a zener diode to change the coin signal down from the PC-powered 12v to 5v to prevent surges damaging the circuit board. If your coin mech is more than 5.5v you may have damaged the ipac.

Oh, shiiiiioooooottt... really? I had no idea about this!
I have a Happ Over/Under Coindoor to which I only have the microswitches wired... but that's what you mean, right? I have the lights wired through my PC's power, they are 12v LEDs.
God, I hope I didn't fry anything... it scares me because this is the only mention I've even seen about this. Thanks for the heads up!
Ginsu Victim:
I don't think you fried anything.
Since you say your buttons work outside of MAME, try setting them back up in MAME. If they work everywhere else, then MAME's the problem.
Arshad:
So what is the proper way to hook something like this up? Drive the coin mech with 5v with the microswitches to the iPac and a separate 12v for the lights only?
Right now my coin mech and lights are all connected together, but I'm assuming I need to desolder all of it and redo it in the manner above. (The current wiring is in bad shape so I was going to replace the wiring anyways...)
