This unit is designed to only work with PS/2 mice
and computers with PS/2 type mouse ports. PS/2
mouse signals and serial mouse signals are different
– adapters will not convert the signals – therefore,
the computer must be equipped with a PS/2 type
mouse port. Serial mouse ports with adapters
cannot be used.
Turn off the computers. Unplug the KVM cables from
the switch. Wait five seconds; then plug the cables
back in and turn the computers on.
Check your Device Manager to be sure that the
correct driver for your mouse (obtained from the
manufacturer, or supplied by the operating system),
has been installed. The CS-84A only supports all the
extra features of the Microsoft Intellimouse and the
scroll wheel function of most other mice.
This unit supports VGA, SVGA, Multisync, and XGA
(interlaced), with resolutions of up to 1920x1440.
The maximum bandwidth is 150 MHz.
Using high quality cables should eliminate possible
video problems.
