Note: The two ends of the control line are different, one is a phoenix connector,
and the other one is a male 9-pin connector. The connecting form is showed as

Pin ①: Connect to the No.2 pin of the male 9-pin connector.
Pin ②: Connect to the No.5 pin of the male 9-pin connector.
Pin ③: Connect to the No.3 pin of the male 9-pin connector.
2) Install the serial driver.
3) Run the COM software and check the connecting state.
4) If it’s OK, then we can control WHD4 by sending RS232 command codes. If not,
probably the control line is bad contact.
