Keyboard
The CPU boots fine with no error messages but the keyboard does not work at all
Wrong cable is plugged in.
Try a different model of keyboard. If the new keyboard works then original one
may be incompatible.
Check that the interconnection cable is connected at the Local Unit and the Remote
Unit. Is the
Link Status LED illuminated?
The other console is active. Gain control by any keyboard action or by pressing left
and right mouse buttons simultaneously.
USB- Keyboard/ Mouse
Your USB-keyboard/USB-mouse does not work
Although we tried to design the devices as transparent as possible, we can’t ensure
that all devices are running. Please check
Appendix F: List of supported USB
devices, on page 106 .
Your 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 colour gradient – single-coloured backgrounds
are optimal and permit highest possible compression rates and highest frame rates.
Your USB- Mouse moves like its on “elastic”
This problem is caused by several factors which lead to a time delay between
mouse movement and display on the screen. Contributions to the total delay consist
of (numerical data are approx. values):
•
Mouse movement/ transmission of data to the CPU (5 – 15 ms)
•
Processing time in the CPU until mouse movement at the graphic output
appears (50 – 70 ms)
•
Transmission of the graphic data into the extender-system and
transmission to the Remote Unit (15 – 45 ms)
