Hot plugging and mouse restoration

It is strongly recommended that you switch off a host computer before
attempting to connect it to the LINDY KVM IP. However, if this is not
possible then you need to ‘hot plug’ the computer while it is still running.
There is not normally a danger of damage to the computer, however, when
mouse communications are interrupted, often they fail to re-initialise when
reconnected. The LINDY KVM IP provides a feature to reinstate mouse
communications once the necessary connections have been made.
There are two main types of data formats used by current PC mice, these are
the older ‘PS/2’ format and the more recent ‘IntelliMouse

®

’ format introduced

by Microsoft. These use slightly different data arrangements and it is important
to know which type was being used before you hot-plugged the computer to
the LINDY KVM IP. The previous setting depends both on the type of mouse and
the type of driver, as various combinations of PS/2 and IntelliMouse are possible.
Using the incorrect restore function may produce unpredictable results and
require the computer to be re-booted.

Which restore setting do I use?

The general rule is that unless both the mouse and the driver are both
IntelliMouse compatible then you need to restore the mouse as ‘PS/2’. An
IntelliMouse can operate in either mode, whereas a PS/2 mouse cannot.

Recognising an IntelliMouse-style mouse
The IntelliMouse format was introduced to support, among other features, the
scroll wheel function. If the mouse has a scroll wheel, then it is likely to support
the IntelliMouse format. If it is a Microsoft-branded mouse, then it will usually
state that it is an IntelliMouse on its underside label.

Recognising an IntelliMouse driver
Before hot plugging to the LINDY KVM IP (or afterwards using only keyboard
control), access the Windows Control Panel of the computer and select either
the Mouse option (on Windows NT, 2000 and XP) or the System option (on
Windows 95, 98, ME). Look for the name of the driver, which will usually
include the words PS/2 or IntelliMouse.

To restore mouse operation when hot plugging:

1 Using a KVM cable set, carefully make the keyboard, monitor and mouse

connections between the host computer and the ports collectively labelled
COMPUTER / KVMA SWITCH on the LINDY KVM IP.

2 Using a keyboard and monitor directly connected to the LINDY KVM IP,

log on and then press

to view the options menu.

3 Select the ‘Restore mouse functions’ option to display:
4 Select one of the following options:

Restore Standard Mouse – if PS/2 mode is required, or
Restore IntelliMouse – if IntelliMouse mode is required.

5 Select the ‘Return to host’ option.
6 Move the mouse a short distance and check for appropriate on-screen

cursor movement. If the mouse cursor darts erratically around the screen,
then cease moving the mouse. This is an indication that the chosen restore
function is incorrect. Try again using the other restore function.
Note: The restore functions predict the likely mouse resolution settings but
may not restore the exact speed or sensitivity settings that were originally
set.
