10.0 Common Problems and Solutions
1. What to do if the VX matrix front panel keys switching not responsive?
Answer: The VX 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 ghosting happens when VGA signals output to display?
Answer: Ghosting is often caused either by the projector, inferior cable quality or long
transmission distance. You are advised to adjust the projector or replace with better
quality cable.
4. What to do if loss of color reproduction happens or no video signal output?
Answer: Please check if connectors at both ends of the VGA signal cable are correctly
connected.
5. What to do if the serial port (usually refer to the computer serial port) fails to control the VX
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.
6. What to do if the corresponding graphics fail to output during VX 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.
