SERVSWITCH™ PROFESSOR
The ServSwitch Professor is designed to support IBM PC compatible 101-, 102-,
104-, or 105-key keyboards and IBM PC keyboard-scan modes 1, 2, and 3; it’s also
designed to work with PC-type CPUs/keyboards that use 5-pin DIN or 6-pin mini-
DIN keyboard connectors. Do
not
try to use the Professor with any keyboard that
uses nonstandard keys, connectors, or keyboard-scan modes.
Although the ServSwitch Professor resists minor transient surges that can be
caused by rapidly cycling power, certain keyboards are sensitive to such transients.
Because your shared keyboard’s power is provided by the Professor, wait at least
three seconds after powering down the Professor before powering it up again, or
the keyboard might not reset correctly.
The ServSwitch Professor supports several types of IBM PC type mice, including
PS/2 mice and RS-232 serial mice. The Professor does
not
support “wheel” mice
such as the Microsoft IntelliMouse
®
.
Because the ServSwitch Professor currently only supports “stream mode”
(continuous) mouse data but older IBM ThinkPad models have to handle mouse
data in “prompt mode” (burst-on-request), don’t try to attach any older ThinkPad
computers to the Professor, either directly or through docking stations. Some
newer models should work with the Professor, but there’s no good way to tell other
than by trial and error. (You can’t damage your equipment by trying—if you have
the wrong kind of ThinkPad, it just won’t work.)
Make sure that the CPUs attached to the system use only the generic Microsoft
mouse driver
MOUSE.COM
, version 4.0 at least and preferably version 9.01 or higher.
If you’re running Windows
®
3.x, this driver must be loaded in Windows as well as in
DOS. Do not, on any of your switched PC CPUs, run any programs or TSRs, or
enter any DOS commands, that change the settings of the mouse port after the
driver has been loaded.
When you first switch between CPUs, you might notice some variation in mouse
sensitivity (how far or fast the mouse moves) from CPU to CPU. This is normal. To
optimize mouse movement, adjust the sensitivity on each CPU according to your
individual preference. (This is usually handled through some kind of software
“control panel,” but the specifics vary depending on the operating system and on
the mouse driver.)
