3.9.1 System Control
The System Control screen is a fault and status screen for the transmitter
communication and control system. System control is divided into:
a.
Parallel Bus - These indicators give the status of each of the 5 hard-wired par-
allel control lines which are distributed to all transmitter controllers.
b.
Serial Communications - This section is monitoring the CAN (Controller
Area Network) which is distributed to all transmitter controllers. As an exam-
ple, Figure 3-31 shows that there is a communication error with the External
I/O board and PA Module #6.
For more information on System Control and Communication faults refer to Section
6, Diagnostics.
