replace the connection cable.
(2) Check if there is signal on the output end. If there is no output signal, it could be that
the cable is broken or the connector gets loosen. You are advised to replace the
connection cable.
(3) Check if the output port number is the same as the controlled port number.
(4) Check the connections of input and output ports are correctly.
(5) If none of the above circumstances happen, it could be internal failure of the product
itself. You must send for repair by qualified technical engineers.
5. What to do if you sense the power leakage during plugging or unplugging of the
input/output ports?
