2.3 (CCU) Remote Control
CCU has a RS232 interface that can connect to a computer for the remote control
purpose. The remote computer can read the following datum:
l
Equipments’ type and profile, such as nominal power, frequency, number of
amplifier modules, maximum power of amplifier module and number of exciters.
l
Machine’s forward power; reflect power; temperature and other working status.
l
Exciter’s operating frequency; forward power; reflect power and other working
status.
l
Each amplifier unit’s forward power; reflect power; temperature; voltage; current
and other working status.
The remote computer can do following controls:
l
RF Switch
l
Setting Power
We can provide software (not free) running on WINDOWS operating system for
remote control; and also provide protocol in order for customer to embed our system
in their remote control system.
Our company’s exciter can also be individually controlled remotely, but we
strongly recommend using the remote control interface of CCU as the only remote
control interface.
If other manufacturers’ exciter is used, remote system can not read the related
information of the exciter through the CCU.
CCU’s parameters can not be changed locally when remote control is enabled
(refer to remote page operation).
2.4 Automatic Power Control & Manual Power Control
Automatic Power Control means to maintain a constant transmission power under
normal working condition. In abnormal working condition, CCU tries to keep the
output power as high as possible but the first thing is to keep the transmitter in safety
condition.
Only with ZHC’s exciter, the Automatic Power Control function is able to work.
