CHAPTER 3: Installation and Preconfiguration
particular, use Windows keyboards if any of your applications require the Windows
keys, and use three-button mice if any of your applications require the center
mouse button.
Other concerns:
• The Matrix ServSwitch emulates several types of mice for the attached
computers, but the actual mice used at your user stations must be the same
type as the stations’ keyboards: Sun mice with Sun keyboards or PS/2 mice
(not serial mice) with PC type keyboards. For more details, see Section 4.3.
• Because the Switch 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 Matrix ServSwitch, either directly or through docking
stations. Some newer models should work with the Switch, 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.)
• If you’re using a PC mouse as the common mouse, make sure that your IBM
PC CPUs 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 the base operating system.
Do not, on any of your switched IBM 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, especially CPUs of different platforms,
you might notice wide variations in mouse sensitivity (how far or fast the
mouse moves) from CPU to CPU. This is normal. There are ways to adjust the
sensitivity of the mouse. (This is usually handled through some kind of
software “control panel,” but the specifics vary depending on the operating
system and—in IBM applications—on the mouse driver.) To optimize mouse
movement, adjust the sensitivity on each CPU according to your individual
preference.
• Although the Matrix ServSwitch 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 Matrix
ServSwitch, wait at least three seconds after powering down the Switch before
powering it up again, or the keyboard might not reset correctly.
