Cabling might have been disturbed during mouse movement. Issue the Send Null
Byte command (see
Section 4.3.13 ) once or twice to get the mouse back in sync.
You need the latest version of the Microsoft mouse driver to stop this from
happening.

A. What type of mouse is it? If it is any other type than those listed as being
supported in item A under Section 5.3.4 , chances are that the ServSwitch
doesn’t support it.
B. If your mouse is a PS/2 type, it might not have been connected to the
ServSwitch when the ServSwitch was turned ON. It might also have been
disconnected and reconnected after the switch was turned ON.
C. Your mouse must be connected to a powered ServSwitch when the CPUs are
booted and when mouse applications are run. Try exiting and reentering
your application; if this doesn’t work, issue the Reset command (see
Section
4.3.12
).

A. Check the settings of your monitor, especially the sharpness control.
B. If you can’t solve the problem by changing the monitor settings, you might
have run cable too far; maximum distance of original Serv cable from any
CPU to the shared monitor, keyboard, and mouse is 25 ft. (7.6 m). The
distance you can run will be less than the maximum if you are using SVGA
video. You might need to upgrade from original Serv cables to coaxial cables
that carry the video signal better. See
Section 4.1.3
and
Appendix B
.

A. If you are trying to use true monochrome video or a 9515, 9517, or 9518
monitor, you need special cables to carry the video correctly. Call Black Box
for technical support.
B. Check the settings of your monitor, especially the sync or color controls.
C. Your monitor might not be capable of synching to the selected video
resolution or frequency (refresh rate). Try a lower resolution or frequency or
a more powerful monitor.
D. If the video problem is not centered on the monitor, check the video strands
of your cables. Tighten any loose connections.
