5. Troubleshooting & Maintenance
1)
When there is a color losing or no video signal output, maybe the cables have already
broken or haven’t been connected well.
2)
When user cannot control the extender by computer through its COM port, please
check the COM port number in the software, and make sure the COM port is in good
condition and the communication protocol is correct.
3)
If a device has connected with an ETHERNET port but TPHD403P can’t recognize it,
please check whether its IP address is the same with another connected device.
4)
When switching , there is no output image:
Check if there is any signal at the input.
Check if there is any signal at the output.
We can check these by using an oscilloscope or a multimeter. If there is no signal
input/output, maybe the input/output cables broken or the connectors loosen,
please change for another cable.
Check if the output port number is the same with the controlled one.
If it is still the same after the above checking, maybe there is something wrong in
the extender. Please send it to the dealer for repairing.
5)
If the static becomes stronger when connecting the video connectors, it probably due to
bad grounding, please check the grounding and make sure it connected well, otherwise
it would damage the extender.
If the extender cannot be controlled through the RS232 port or by the IR remote, the unit
may have already been broken. Please send it to the dealer for repairing.
