1. Both cables (P64 and P66) are required.
2. A crossover coupler is provided for unit-to-unit (U2U)
networking. Unplug the red cable from P64 on the
microprocessor and I/O board and connect it to one side
of the crossover coupler. The first customer connection
point is to P64 on the microprocessor and I/O board.
The second customer connection point is to the other
side of the crossover coupler. This connects the
microprocessor and I/O board and display to the
private U2U network.
