Matrix Switching System—User Manual

9.0 Troubleshooting

1. What to do if the HDMI matrix front panel keys switching not responsive?

Answer: The HDMI matrix front panel keys employ scanning testing and require longer

response time. Press the keys for 2 seconds and then release. This way, key

switching will be responsive in operation.

2. What to do if matrix does not display or color display is abnormal after hot plug?

Answer: Switching of the matrix system goes through the IC chips. If the voltage

difference between the input signal equipment and the matrix equipment is too

large, hot plug could easily cause damage to the IC chips. Please turn off

power to the system before plugging or unplugging.

3. What to do if loss of color reproduction happens or no video signal output?

Answer: Please check if connectors at both ends of the HDMI signal cable are correctly

connected.

4. What to do if the serial port (usually refer to the computer serial port) fails to control the

HDMI matrix?

Answer: Check that the communication port set by the control software is correctly

connected to the corresponding serial port of the equipment. Also, check if the

computer communication port is in good order.

5. What to do if the corresponding graphics fail to output during HDMI matrix switching?

Answer:

(1) Check if there is signal on the input end. If there is no input signal, it could be that the

input connection cable is broken or the connector gets loosen. You are advised to

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) 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.

6. What to do if you sense the power leakage during plugging or unplugging of the

input/output ports?
