4.2 Monitor and Control (M&C)
The Monitor and Control (M&C) monitors the KST-2000L and provides configuration
updates to the up converter, down converter, and HPA when necessary. Refer to

The KST-2000L configuration parameters are maintained on battery locked RAM, which
provides recovery after power down.
The M&C functions include extensive fault and status reporting. All KST-2000L func-
tions are accessible through the remote communications interface.
The M&C is composed of the following sections:

The microcontroller is an Intel 80C32 operating at 16 MHz. The micro-controller con-
tains 256 bytes of internal RAM. The external ROM is 29F020 (256 kbytes). The battery
backed RAM is 8 kbytes in size.
The non-volatile RAM allows the KST-2000L to retain configuration information with-
out prime power for 1 year.
The system is ready for final installation to the antenna feed. Perform the rest of
the system alignment to applicable international, national, or local regulations.
