Hi, so I have an ACJr with serial port. Pins 1 and 2 of the cable are specified as "external input" and "external output" or something along those lines.
So if I wanted to use it with a float switch, do I just put the switch between these two pins? (Assuming I "breakout" the wires or otherwise have access to the pins/wires)
Or do I use the external input pin and the signal ground pin?
Thanks!
