Hot plugging and mouse restoration
It is strongly recommended that you switch off a host system before attempting 
to connect it to the Adder TS4. However, if this is not possible then you need 
to ‘hot plug’ the system while it is still running. There is not normally a danger 
of damage to the system, however, when PS/2-style mouse or IntelliMouse 
communications (i.e. non-USB) are interrupted, often they fail to re-initialise 
when reconnected. The Adder TS4 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 non-USB 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 
system to the Adder TS4. 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 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 Adder TS4 (or afterwards using only keyboard 
control), access the Windows Control Panel of the system 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 link cables, carefully make the keyboard and mouse connections 
between the host system and the appropriate ports on the Adder TS4.
2  Press and hold the 
SELECT
 button on the Adder TS4 front panel for five 
seconds, until the 
SYSTEM
 readout shows C (Configuration mode).
3  Choose one of the following actions:
•  To restore a standard PS/2-style mouse: Press     
•  To restore an IntelliMouse: Press     
  The 
SYSTEM
 readout will show the entered characters and then return 
to show C when you press 
. The mouse restoration should now be 
complete.
Note: The restore functions predict the likely mouse resolution settings but 
may not restore the exact speed or sensitivity settings that were originally 
set.
4  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.
5  To exit from Configuration mode, press
