the lid while holding on to the 6 pin Phoenix connector. Please do not hold the wall mount tabs as these are
designed to break off if not required!
To set select these configurations, open the Gateway and select the A bank of switches (A1 or A2 or A3)
on the small ProtoCessor module that sits on top of the ProtoCarrier (inside the Gateway).
