Compact Scaler Switcher (with PoE)
7. Troubleshooting & Maintenance
1)
When the image displays static snow, this is not usually due to a faulty unit.
l
Usually caused by bad quality cables. Please try another high quality cable.
l
The video cables are loose, please check the connections.
2)
When it is not able to detect EDID, the HDMI cable may be broken or loose.
3)
When user cannot control the switcher 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.
4)
If the
POWER
indicator doesn’t work or does not respond, please make sure the
power cord is securely connected.
5)
When switching, there is no output image:
l
Check with an oscilloscope or multimeter to see if there is any signal at the
input/output end. If there is no signal input/output, the input/output connection
cord may be broken or the connectors are loose. Please change the cable or
connect again.
l
If it is still the same after the above checking, maybe there is something wrong
in the switcher. Please send it to the dealer for fixing.
6)
If the static becomes stronger when connecting the video/audio connectors, it is
probably due to incorrect grounding. Please check the grounding of the unit as it
may permanently damage the device.
7)
If you are not able to control the scaler switcher from the front panel buttons, but
you can through RS232 commands, maybe the front panel buttons are locked.
Please send command
50605%
to unlock the buttons.
8)
If the buttons on the front panel, RS232 port, or IR remote cannot control the scaler
switcher, the switcher may be defective. Please send it to your dealer for repair.
