8.0 Communication Protocol/Control Command Code
Communication Protocol: Baud rate 9600bps, no odd or even calibration bit address,
8bit transmission address, 1bit stop address. Please refer to the
“Command list.pdf” in the CD-ROM for more related Command Code information.
9.0 Troubleshooting
1. What do I do if the HDMI matrix front panel switching keys are not responding?
Answer: The HDMI matrix front panel keys employ scanning testing and require longer response time. Press and hold the keys for 2 seconds. This will ensure key switching will be responsive in operation.
2. What do I 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 the power to the system before plugging or unplugging.
3. What do I do if there is a loss of color reproduction, or no video signal output?
Answer: Please check if connectors at both ends of the HDMI signal cable are correctly connected.
4. What do I 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 to see if the computer communication port is in good order.
5. What do I 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 loose. 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 loose. You are advised to replace the connection cable.
23
Matrix Switching System—User Manual
(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.
6. What do I do if I sense 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.

Appendix A RS-232 Communication Protocol
This AV Matrix RS-232 communication protocol uses fixed length with 5 bytes of information as define below. The default baud rate is 9600 bps, no parity, 8 data bit and
1 stop bit. Command timeout is 300ms, and byte to byte timeout is 30ms.
Use the RS-232 connecting cable to connect the computer serial port to the RS-232 communication port of the Matrix device. The computer can control the Matrix device via
RS-232. Aside from using the front panel keys for operation, you are also permitted to use the RS-232 connection port for remote operation.

Example: switch output 6 to the input 3.
Byte 1 (DB) is 0x20
– Device: Identifier + Device ID = 0x20 + 0 = 0x20
Byte 2 (RB) is 0x01
– Request: Switch Video Output Channel = 0x01
Byte 3 (IB) is 0x06
– Index: Output 6 = 6
Byte 4 (VB) is 0x03
– Value: Input 3 = 3
Byte 5 (CB) is 0x93
– CRC code from Byte 1 to Byte 4. (CRC4)
CRC Calculation
CRC 0 = 0 (initial value)
CRC 1 = CRC_ TABLE [CRC 0 ^ Byte 1] = CRC_ TABLE [0x00 ^ 0x20] = 0x23
CRC 2 = CRC_ TABLE [CRC 1 ^ Byte 2] = CRC_ TABLE [0x23 ^ 0x01] = 0x9F
CRC 3 = CRC_ TABLE [CRC 2 ^ Byte 3] = CRC_ TABLE [0x9F ^ 0x06] = 0x8D
CRC 4 = CRC_ TABLE [CRC 3 ^ Byte 4] = CRC_ TABLE [0x8D ^ 0x03] = 0x93
