2. Key Functional Indicators
1) Monitoring and alarm functions: forward power detection, reverse power detection, temperature monitoring, temperature alarm, and standing wave alarm with enable options. The standing wave and temperature alarm pins support direct LED connection for alarm indicators (no additional resistors required).
2) Control function: Remote control and monitoring can be achieved via RS485.
The control parameters include power supply and power cut-off control, alarm threshold setting and power setting.
