These connections connect the control from Moog Main Controller to the payloads.
This provides a method of communicating from the system control signal path to the
payloads via the 62H command as found in the protocol document. The serial ports
may be user configurable as either single ended (RS232) or differential (RS422). All
signal ground wires are connected to the systems negative input power supply.
