1.2.3 Transmitter Control System
The transmitter uses a distributed architecture control system. This means that each
transmitter sub-system is responsible for its own monitoring and protection and
simply reports back to the Main Controller for display on the GUI (Graphical User
Interface) or to a remote interface. The heart of the system is the 376 Micro Module
which is used in all of the transmitter systems for control, monitoring and
protection. The Micro Module is used on each of the following controllers and sub-
systems:
a. Main Controller Board - This board is responsible for transmitter control and
monitoring. However, with the distributed control architecture, it is not
directly responsible for protection of the individual transmitter components. It
merely gathers all status and fault data from the individual sub-systems and
reports that information to the operator. The Main Controller is responsible
for system level control (issues which effect multiple systems) since it is the
only part of the control system which can monitor the entire transmitter.
b.
Module Controllers (1 in each module) - Responsible for protection and con-
trol of the PA Module. Report directly to the Main Controller Board.
c. RF Monitor Board - Responsible for cabinet VSWR protection and monitor-
ing of combiner reject loads. Reports directly to the Main Controller.
d.
Power Supply Monitor Board - Responsible for control and monitoring of the
PA power supplies and distribution of the low voltage. Also responsible for
monitoring the cooling system including temperature, flow and leaks. Reports
directly to the Main Controller.
e.
External I/O Board - Provides all customer interface connections including
parallel remote control and serial remote control. Reports directly to the Main
Controller.
1.2.3.1 Graphical User Interface
The front panel user interface is a 1/4 VGA, LCD touchscreen display. The
touchscreen display uses software buttons to monitor the transmitter. Hardware
buttons for the primary transmitter functions such as ON, OFF, RAISE and
LOWER are provided on the overlay panel next to the display.
