Troubleshooting - Monitor
Video not present on all monitors.
Check the power supply connection at the transmitter and Receiver
Units.
Verify that the power LED is illuminated on the transmitter and receiver
units. If not, the internal power supply may be damaged or there may be
an internal error.
Verify all CATx or fiber cable connections.
Verify that the Link Status LED is illuminated. If not, there may be a
problem with the interconnection cable:
Check the Data Error LED. If it is illuminated or blinking, the cable could
be too long, too high attenuation or too much EMI interferences.
Check settings of the graphic card. Try connecting a monitor to the local
output to see whether or not there is a signal.
Video picture is unstable or jittery
With high monitor resolutions, the data volume that can be transferred
may exceed the available bandwidth, so the data throughput must be
reduced. For this, the device uses a RLE compression algorithm. If the
necessary compression factor is not reached, not all pictures of the
graphic card are transferred (frame dropping) and the video presentation
may begin to “judder”.
Hint: Use a lower resolution, which is a little larger than the resolution of
the stored film material. If the monitor has a higher resolution, then the
monitor can take over the scaling of the video data. For the image quality
it is irrelevant whether the scaling is done via the CPU or via the monitor.
Hint: Set the color depth to 18 bits. Usually the human eye is not able to
differentiate between so many different colors with moving pictures. A
reduction on 18 bits makes the data volume that has to be transferred
smaller without loss of image quality.
Troubleshooting - Keyboard
The computer boots properly but the remote keyboard does not work
Verify the keyboard connection at the transmitter / computer and receiver
/ keyboard are connected properly.
Try a different model of keyboard. If the new keyboard works the original
one may be incompatible.
Check that the interconnection cable is connected at the Local Unit and
the Remote Unit. The Link Status LED should be illuminated.
The other console is active. Gain control by any keyboard action or by
pressing left and right mouse buttons simultaneously.
