8bit transmission address, 1bit stop address. Please refer to the “Command list.pdf” in the CD-ROM for more relative Command Code information.

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.

22


(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?

Answer: It could be that the equipment power is not properly grounded. You must properly ground your equipment; otherwise product life can easily be shortened.

7. What to do if the LCD displays normally and the communication port has return code but no image output?

Answer:

(1) It could be that the output/input connectors got loosen. Simply replace the connectors.

(2) It could be the connection cable short-circuited. Simply replace the cable.

(3) It could be the connection cable is broken. Simply replace the cable.

8. What to do if the HDMI matrix panel keys and communication ports are out of order?

Answer: Check if the equipment power input is in good contact and the computer communication ports are in good order. If yes, it could be some internal failure of the product, please send for repair by qualified technical engineer.

9. What to do if operation and function failure occurred?

Answer: Check if the equipment and the matrix system are in proper connection. If the problem persists, send the product to the maintenance center for repair.
