6 Beneath the Screens field, click the ‘+’ button to display the Add Screen 
dialog so that you can add a new screen (computer system):
7  In the ‘Screen Name’ field, enter the ‘Hostname’ (see step 4) of one o\�f the 
computer systems and choose the corresponding ‘Switch Number’ (its port 
number on the Adder TS4 unit). 
  You can optionally use the other controls within this dialog:
 Aliases - Enter one or more unique names that you would prefer to use for 
the system.
 Dead.Corners - This option allows you to define one or more corner regions 
of the screen where you need to prevent switching to another screen. This is 
most often used in the corner where the Windows Start button is located so 
that you do not accidentally switch screens. Check one or more of the boxes 
to select the appropriate corner(s) and use the ‘Size‘ field to define a square 
area (side length of the square in pixels, extending out from the corner) in 
which switching should be disabled. 
8  Click the OK button when all items have been entered.
9  Repeat steps 6 to 8 to define each system, including the primary serve\�r 
system itself.
Dead corners, size?
10   You now need to define the positional relationships between the various 
screens of the systems, using the lower part of the Screens & Links window. 
11   Use the drop down controls (ringed in red), to select the border (left, right, 
top or bottom) of a screen, and the screen to which it should switch, e.g.
   0 to 100% of the right of PC1-Primary goes to 0 to 100% of PC2
    The above setting will change to PC2 when the mouse exceeds the right 
border of PC1-Primary.
    See the next page for typical setup examples 
Ü
12  Click the ‘+’ button to add your entry to the list. The above entr\�y would be 
added to the list as follows:
   PC2 is right of PC1-Primary
13   Repeat steps 11 and 12 for each screen border that leads to another screen. 
This must be done for both switching directions, i.e. ‘...right of PC1 goes to 
PC2’ and left of PC2 goes to PC1’.
    The percentage 
values only need 
to be changed if 
different switching 
routes from the same 
screen are required. 
In the example right, 
the bottom half of 
the right side of PC1 
switches to PC3, while 
the top half goes 
to PC2. This would 
expressed as follows:
   0 to 4% of the right of PC1-Primary goes to 0 to 100% of PC3

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 origin\�ally 
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 
 .

Operation
In operation, the Adder TS4 allows you to quickly switch between up to f\�our 
systems. One system can be accessed at a time, whereupon the common 
keyboard and mouse are linked to that system. The Adder TS4 deceives the 
other systems that they still have a keyboard and mouse connected to them in 
order that they respond quickly and correctly once they are again selected.
The SYSTEM readout
On the front panel of the Adder TS4 unit, the SYSTEM readout indicates either: 
•  The computer system to which the keyboard and mouse are connected, or
•  An alternative mode of operation, such as password protected mode, 
configuration mode, upgrade mode, etc.
Typical SYSTEM readout displays are:
, ,  or   Indicates the currently selected system. The selected channel 
will also be indicated on the remote control.
  The Adder TS4 is disabled, no system is currently selected. The 
remote control will not show any channel indication.

Changing hotkeys
Hotkeys are two normal keyboard keys that, when pressed simultaneously with 
a third key, signal to the Adder TS4 that you are sending a message specifically 
to it and not to the currently selected system. The hotkeys are ordinarily  and 
, while a third keypress determines what you want the Adder TS4 to do, e.g 
change to different system, invoke password protection, etc.
If the standard  and  hotkeys are also needed for computer system tasks, 
you can change them for another combination, as discussed below.
To change the hotkeys

Mouse button switching modes
You can use a three button mouse to switch between systems. However, when 
used in this way, the action of the middle mouse button or scroll wheel click 
is ‘trapped’ by the Adder TS4 and is not passed to the system. Thi\�s makes it 
unavailable for use in controlling applications on the selected system. The scroll 
wheel scrolling action is unaffected and passed on normally to the systems, only 
the scroll wheel click is used by the Adder TS4.•  To use the mouse buttons to change systems, use options U1 (default) or\� 
U4.
•  To use the scroll wheel click/third mouse button with the systems, use 
options U3 or U5. 
•  To report only a simple 2-button mouse to the systems, use option U2. 
To change the mouse button switching modes 
1  Enter configuration mode: Press and hold the 
SELECT button until the SYSTEM 
readout shows c.

reports IntelliMouse mode to the systems. 
3  When the mouse button selection has been made, press 
 to fix it and 
then press   to exit from configuration mode.
All channel/active channel cycling
The Adder TS4 provides the option, when cycling between the system channels, 
to visit each channel (irrespective of whether an active system is connected) 
or to only select active channels. You can affect the keyboard/mouse setting 
independently from the front panel SELECT switch setting.
To change keyboard/mouse channel cycling 
1  Enter configuration mode: Press and hold the 
SELECT button until the SYSTEM 
readout shows c.
2  Press

Upgrading
Like all Adder products, the internal software (firmware) of the TS4 is designed 
to be easily upgraded in order to take advantage of a continual process of 
improvement and innovation. 
You can discover the current version of your Adder TS4 in two ways, either using 
the upgrade application (discussed later) or within the configuratio\�n mode as 
discussed next.  
To discover the current firmware version1  Enter configuration mode: Press and hold the 
SELECT button until the SYSTEM 
readout shows c.
2  You need to discover the three digits of the firmware release individually, as 
follows:
•  Press 
   to discover the first firmware release digit.
•  Press 
   to discover the second firmware release digit.
•  Press 
   to discover the third firmware release digit.
  At each stage, the 
SYSTEM readout will momentarily show = and then the 
relevant digit, before returning to the c prompt. For example, the respective 
digits 1, 4 and 6 mean that the firmware version is v1.46. 
3  Once completed, press 
  to exit from configuration mode. 
To upgrade the Adder TS4
1  Download the latest TS4 firmware upgrade file from the Adder website: 
www.adder.com. The upgrade files are compressed using pkzip format 
which you will need to decompress them. If you do not have pkzip, go to 
www.pkware.com to download the latest version. Place the decompressed 
upgrade files onto the Windows system that will be connected (via a vacant 
serial port) to the Adder TS4 unit. 
2  Remove power from the Adder TS4. If any systems are active, either switch 
them off or remove their keyboard link connectors from the Adder TS4. If an 
optional power supply is used, remove it.
3  Connect the supplied upgrade cable between the remote control socket 
on the end of the Adder TS4 unit adjacent to the Adder logo, and a vacan\�t 
serial port on the system containing the upgrade files. 
4  On the underside of the unit, click mini switch 7 to its ON position.
5  Re-apply power to the Adder TS4 and switch on the system to be used for \�
the upgrade. The SYSTEM readout will show .  7 
Click the 
Browse... button and locate the TXT file that accompanied the 
upgrade utility. Highlight the TXT file and click the Open button.
8  Click the 
Advanced... button and in the subsequent dialog, ensure that the 
Serial Port entry matches the port to which the upgrade cable is attached. 
Also select the Program and verify option. Click the OK button.
9  Click the 
Query Unit button to check the name and version of the current 
firmware - the application will interrogate the TS4 via the upgrade cable. 
Once the version information is displayed, check that the Intended Target 
Units field matches the Unit Connected field and the New Firmware Version 
field exceeds that of the Current Firmware Version.
10   Click the 
Upload Now button to begin transferring the upgrade data from 
the system to the Adder TS4. The progress of the upload is shown in the 
status bar (indicating the advancement of the current task) and the progress 
bar (indicating the progress of the upload as a whole). The SYSTEM readout 
will show u.
    During the upload, all buttons become disabled except for the 
Abort 
button. The upload can take as long as fifteen minutes. Should you nee\�d to 
abandon the upload at any stage, click the Abort button.  
    Following the upload, a verification will be carried out and the results 
displayed within the upgrade application window. 
11   When complete, switch off the Adder TS4, disconnect the upgrade cable, 
return mini switch 7 to its OFF position and resume operation of the Adder 
TS4 in the usual manner.

Troubleshooting
If you experience problems when installing or using the Adder TS4, please check 
through this section for a possible solution. If your problem is not listed here 
and you cannot resolve the issue, then please refer to the ‘Getting assistance’ 
section.
Mouse does not move cursor on screen.•  If you move the mouse and the activity indicator (dot on 7 segment disp\�lay) 
does not flash then the Adder TS4 is not receiving data from the mouse. 
Check the mouse connection to the Adder TS4, try resetting the mouse 
using the reset function or re-powering the Adder TS4. If you are attempting 
to connect the Adder TS4 to a system with a PS/2 mouse connection 
that has not been powered down then you will need to use the mouse 
restoration functions.
Keyboard does not function or functions intermittently. Num lock light 
does not always come on when the num lock key is pressed.
•  Some older keyboards were designed for use with specific systems and 
are not truly AT or PS/2 compatible. These are not common but if you 
experience problems try another keyboard.
Mouse causes channel to change.
•  Some cheaper mice are not fully compatible with the Adder TS4 and can 
lose data causing the channel to be changed (if mouse switching of channels 
is enabled). Ensure that you are using a Microsoft compatible mouse driver 
on your system. Some other manufacturers’ drivers may switch the mouse to 
use a proprietary mouse data format not supported by the Adder TS4. If you 
have unplugged and re-connected a mouse to the Adder TS4 then ensure 
that you reset it using the mouse reset function.
Mouse jumps around the screen after disconnecting the mouse cable or 
powering down the Adder TS4.
•  The mouse data format may be out of synchronisation with that required by 
the system (PS/2 or Intellimouse). Try the ‘restore Intellimouse’ function (F6) 
to resolve the problem or repower the system.
