Acorn Inputs not Registering <24 volts not connected>

[morchips]

Hello all,

I imagine this is something incredibly dumb.

I got a new Acorn off Amazon a few days ago (need to get the SN), but I got just about everything else working except for the 8 inputs. Basically, I have tried pulling high and low, and neither register either on the LED, nor on the centroid app. I configured the inputs (5 and 6) as Home all, and Limit all. Home all is NO, Limit all is NC, both test correctly with a meter.

Servos, outputs, everything else works just peachy.

Any idea what I am doing wrong?

Thanks!

Did you connect +24VDC to one of the two input common terminals, at the ends of the input plugs?

They are labeled "24IN" on the board. Both are connected together internally, so you only need to connect a wire to one of them.

That was it, much appreciated!

I had missed that was a 24V supply, I assumed 24V was already supplied.
