ATLAS Analogue
4.3.5.1 Transmitter Control
The Main Controller is the central point for all system control, metering and
diagnostics. It reports this information to the operator via the Graphical User Interface
or GUI and through several remote control options.
4.3.5.1.1 Graphical User Interface (GUI)
The GUI is a touchscreen LCD display which is equivalent to 1/4 of a VGA display.
This is the primary local interface for the operator but is not required to operate the
transmitter. The primary operator controls, ON, OFF, RAISE, LOWER are located on
the front panel next to the GUI. Operation and navigation of the GUI is covered in
Section 3 of this manual.
4.3.5.1.2 Remote Controls
There are 3 remote control and monitoring options which can all access information
gathered by the Main Controller via the External I/O Board. These options are shown
on the left side of Figure 4-1.
a. Standard Parallel Remote Control System - The External I/O Board has con-
nections for dedicated remote control systems with the standard parallel control
inputs, status outputs and analog metering outputs.
4.3.5.2 Serial Connections
The Main Controller has 5 serial ports (these are not for remote control applications):
a.
2 RS-485 serial ports, J5 and J6, are used to control the TVS-D660 exciters.
b.
1 serial port (part of ribbon cable J11) is connected to the External I/O Board but
is not used at present.
c.
1 serial port, J90, is available for operator connection to run the In-System
Programming or ISP software, supplied by Harris, to update the software for the
Main Controller and/or any other micro in the transmitter.
d.
1 serial port, J7, is used by the optional eCDi interface.
