Section 9A
Operator Interface
9A-9
Important: The color CRT operator panel has an additional internal power
supply that is used to power the color CRT. The ac power supply cable,
cable C03, provides ac power to the sub power supply terminal on the rear
of the color operator panel as shown in Figure 9A.3. The ac power supply
is jumpered internally to the color CRT power supply from operator panel
power supply.
Fiber optic connection is made through the operator panel I/O interface
card mounted on the back of the operator panel. Table 9A.F shows the
connectors used to make the fiber optic connections to the I/O ring. Each
module connected to the system I/O ring has an optical transmitter and
receiver. Fiber optic cables connect transmitters to receivers to form the
I/O ring. Refer to page 7B-1 for additional information on fiber optic
cables and connectors. Figure 9A.2, Figure 9A.3, and Figure 9A.4 shows
the location of these connectors.
