Networking Installation Notes:
1. On units with the standard Small Graphics display, the customer connection point for unit to unit
(U2U) networking is to P64 on the microprocessor I/O board.
2. When the optional Large Graphics display is used, both cables (P64 and P66) are required.
3. On units with the optional Large Graphics display, remove the red crossover cable from P64 on
both display and I/O boards. The first customer connection point is to P64 on the I/O board. The sec-
ond customer connection point is to P64 on the rear of the large display. This connects the I/O board
and the large display to the private U2U network.
