thicker shielded twisted-pair wire with drain. Two
twisted pairs or three conductors are needed. Wire A
on MB2 of unit 1 must be connected to A on MB2 of
unit 2, wire B on unit 1 goes to B on unit 2, and wire
C on unit 1 goes to C on unit 2. Repeat this wiring
for any other units in the system. Connect all of the
drain wires and ground the drain wire on one end of
the assembly only.
