The Control I/O Panel is used to charge the batteries, cycle power to the receiver, control the

All ports are MS (military spec) connectors. Cable attachment is made by:
Lining up the slots on the
cable plug with the keys on
the outside of the panel
connectors.
Pushing in the cable plug.
Twisting the knurled ring to
the right.
Only the battery connector is
female, while the others are male.
The connectors are different sizes
to avoid misconnection.
