There is no picture.
 Check the power supply connection at the Local and Remote Unit. Is the Power LED at the Local and Remote
Unit illuminated? If not, the internal power supply may be damaged or there may be an internal error.
 Check that the interconnection cable is connected at the Local Unit and the Remote Unit. Is the Link Status
LED illuminated? If not, there may be a problem with the interconnection cable:
 Are there e rrors through data transmission over CATx- cable (cable too long, too high attenuation or too much
EMI interferences)? Is the Data Error LED illuminated or blinking? If yes, check cable length and environment.
 Video Okay LED is dark: CPU does not provide a video signal – Check settings of the graphic card. Try
connecting a monitor to the local output to see whether or not there is a signal.
Jittery pictures at video presentations
 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 “jitter”.
 Hint: Use a lower resolution, which is a little larger than the resolution of the stored film material. If the monitor as
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 16/24Bit AUTOSELECT. Usually the human eye is not able to differentiate between
so many different colors with moving pictures. A reduction to 16 bits reduces the data volume that has to be
transferred without loss of image quality.
Troubleshooting – USB Keyboard / Mouse
USB Keyboard / USN Mouse do not work
Although we tried to design the devices as transparent as possible, we can’t ensure that all devices are compatible.
USB Mouse makes ”jerky leaps”
 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
mouse may make jerky leaps.
Hint: Use a lower resolution or a background which can be compressed better: Please avoid photo-backgrounds
or color gradient – single-colored backgrounds are optimal and permit highest possible compression rates and
highest frame rates.
