RF power control and power supply control 2 2 System Internal Network Internal network is built through CAN bus CCU amplifier modules and exciters are connected on the CAN bus on which the CCU read information from amplifier module s and exciter s and control the exciter s power to make the machine s Automatic Power Control work Fach unit on the CAN bus have a unigue CAN address and the setting rules are as below Exciter A l Exciter B 2 Power Amplifier Unit A 3 DIP switch Power Amplifier Unit B 4 DIP switch Power Amplifier Unit C 5 DIP switch If there is no corresponding unit or use the other manufacturer s exciter the corresponding CAN address is reserved If the exciter breaks off from the CAN bus the machine s Automatic Power Control can not work If an amplifier module breaks off from CAN bus the central control unit will regard forward power and reflected power of the amplifier as zero Consequently CCU unbalance power control strategy will be deployed Other manufacturer s exciter can be used but can not be connected on the internal CAN bus network not matter there s a CAN interface or not due to the restriction of the internal communication protocol You can confirm if a unit is connected on the CAN bus through the status display page on CCU s LCD 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 fol
