Hey guys -
Maybe it was because it was early this morning when I read it, but something about this didn't make sense.
In daisy chaining the grounds together, is it one wire running from the IPAC ground to the grounds on both joysticks and buttons, or do you have two seperate wires?
I'm not sure I asked that question well, but maybe someone will understand what I meant! :)

I assume you're talking about daisy chaining the ground from the iPac to 1 Joystick and N-Buttons... Yes it's fine to use just one ground, that's what I did on my setup.
I ran the ground from the iPac Player 1 GND to the joystick and then from the joystick to the buttons, works a treat. The only exception was for the Player 2 button which I wired to the Player 2 GND, however I'm not sure even that was necessary?

Wire your ground from one ground on the I-PAC, daisychaining to all the COM leads on your microswitches, ending with the chain on a second ground on the I-PAC. If there's a single break anywhere in your daisychain, all your buttons will still work because each will have a path back to ground.
You don't *need* to connect up to the second ground on the I-PAC, but it does give you a measure of redundancy.

Thanks! I sort of saw it as being one wire that ran from the IPAC ground, through ALL the switches, and back to the ground at one point, but then like I said - and I don't recall what it was even today - something made me wonder if I'd read that wrong.
Thanks again y'all!
