Hot plugging and mouse restoration
It is strongly recommended that you switch off the computer system
before attempting to connect it via the Wizard Extender modules.
However, if this is not possible then you need to ‘hot plug’ the Wizard
Extender modules while power is still applied to the system. There is
not normally a danger of damage to the system, however, when
mouse communications are interrupted, often they fail to reinitialize
when reconnected. Wizard Extender modules provide 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 Wizard Extender modules. 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 system to be rebooted.
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’.
Recognizing an Intellimouse-style mouse
The Intellimouse format was introduced to support, among other
features, the scroll wheel function. If your mouse has a scroll wheel,
then it is likely to support the Intellimouse format. If you have a
Microsoft mouse, then it will usually state that it is an Intellimouse on
its underside label.
Recognizing an Intellimouse driver
Before hot plugging your Wizard Extender (or afterwards using only
keyboard control), access the Windows Control Panel 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 Carefully connect the Wizard Extender modules to the system and
its keyboard, mouse, monitor, audio and serial device.
2 Simultaneously, press the hotkeys (by default,
and
) along
with
to enter configuration mode.
3 Enter the appropriate restore function code:
•
PS/2
– press
•
IntelliMouse
– press
4 To exit configuration mode, press
.
5 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.
Microsoft and Logitech -specific mouse settings
In certain installations some Logitech mouse drivers may lose the
action of the mouse buttons when used with the standard ‘Microsoft
compatible’ signalling protocol used between the modules. To solve
this problem, select the ‘Logitech compatible’ mouse signalling
protocol.
To change mouse signalling protocols
1 Simultaneously, press the hotkeys (by default,
and
) along
with
to enter configuration mode.
2 Enter the appropriate protocol code:
•
Microsoft compatible
– press
•
Logitech compatible
– press
3 To exit configuration mode, press
