Title: Issue with Dual Ipac Ultimate setup
Post by: Davies023 on September 11, 2021, 11:22:08 am
Hello all,

First time builder here! I went with ultimarc RGB buttons and a dual Ipac ultimate set up. Wired everything up and thought I was good to go... Tested right side control panel with Ipac #2, all buttons / joysticks responded, woo!! When I switched over to the left side of the panel with Ipac #1, my LEDs are working, but I only
Have one input.. the only button that is working on the whole side of that panel is Player 1 start.  I’m very new to this, but the only difference between my left and right side is that I skipped a few extra grounds in my daisy chain due to spacing. Could this be the issue? The ground is closed at the end, and when I looked at the right side I hadn’t even closed their ground and it was working properly.   I’m not super knowledgeable about wiring and such, but everything looks like it SHOULD work.

I confirmed it wasn’t a bad Ipac because I swapped iPacs around and functionality remained the same on both sides.. any help is appreciated. My next step is likely to rewire everything on the left but I am wondering if there is just maybe something I missed or something I should look for to test.  If you have suggestions please try to explain like I’m 5, haha. Thanks!

You skipped wiring some grounds... on purpose?? :lol

You need to daisy chain ALL of the grounds back to GND on the iPAC for everything to work properly.  Without seeing a pic or a wiring diagram, that is most likely the problem.
