1.1 FUNCTIONS
The control system is made up by some “Slave” boards, which check locally the amplifier modules,
and a “Master” board to monitor the status of the Slave boards in each module and show on a graphic
display all the checked parameters. The number of the Slaves changes depending on the output power of
the amplifier. The communication between Master and Slaves is made via I
2
Cbus standard. The Master
board reads the overall parameters of the equipment (forward and reflected power and unbalancing),
polls (interrogates in sequence) the local boards, shows on the display the values requested by the user
and indicates alarm conditions, if any. Besides it realizes a serial data interface to an external system
able to analyse the working parameters of the equipment, using the RS232 and RS485 communication
protocols.
At start-up, the display of the Amplifier Control shows an informational message concerning the equip-
ment and the firmware version.
The main menu has: a list of the amplifier modules, the measure of some parameters of the powers in antenna,
a window with icons to show the alarm status and some general information, that is date, time, temperature
inside the module and, for FM equipment, transmission frequency.
In the Amplifier List, next to each module, you can find the following symbols:
AMPLIFIER CONTROL
if the communication with the slave is correct and then
if the communication with the slave is interrupted
ON
if the amplifier module is OFF
OFF
if the amplifier module is ON
