Welcome  
Introduction  
Thank you for choosing the AdderLink X2 Multi Screen extenders. Comprising  
two compact modules, these extenders allow you to place multiple video  
monitors and serial devices together with a keyboard, mouse and audio  
peripherals up to 200 metres from a computer system. In addition, locally  
connected video monitors, keyboard, mouse and speakers allow two users to  
simultaneously view the outputs of the host system and also take control of  
the system, providing it is not being used by the other user. A user relinquishes  
control two seconds after their last key press or mouse movement.  
separate channels. For both variants, a local module attaches to the computer  
system and provides connections for the local peripherals while the remote  
module is placed up to 200m away and handles the remote peripherals. The  
long distance link between the two modules is made by either two (MS2 model)  
or four (MS4 model) Category 5, or higher, twisted pair cables.  
Special circuitry within the remote module allows you to make adjustments to  
the sharpness and brightness settings to suit your own preferences. Additionally,  
a Skew adjustment is also provided to counteract the effects of uneven lengths  
of twisted pair cables that are used to carry the video signals.  
Two variants of the Multi Screen extenders are available, the MS2 model allows  
two video and serial channels, while the larger MS4 model provides four  
Two (MS2 model) or four (MS4  
model) video and serial device  
channels are available at the  
REMOTE module.

Installation and operation  
Installation  
LOCAL module switches (continued)  
The installation of the X2 Multi Screen extenders is straightforward and can best  
be achieved in most cases by following these stages for each module:  
LOCAL Switch 1  
OFF: Normal operation.  
• Stage A  
• Stage B  
• Stage C  
Check or set the configuration switch settings  
Mount the module  
ON: (Before power is applied) Places the LOCAL module into flash upgrade  
mode so that the internal software can be changed. Please see the ‘Flash  
upgrade’ section in the ‘Special configuration’ section.  
Connect the cables  
ON: (Whilst power is applied) Places the REMOTE module into password  
override mode. This allows any pre-configured passwords to be altered  
- particularly useful when they have been lost or forgotten. Please see the  
‘Password override’ section in the ‘Special configuration’ chapter.  
Stage A - Configuration switch settings  
The basic operation of the LOCAL and REMOTE modules are controlled by the  
banks of four switches located on the side of each module. The switches are  
monitored at all times and may be changed when power is on or off (the only  
exception to this rule is switch 1 of the LOCAL module which initiates slightly  
different functions depending on the power state when it is switched).  
LOCAL Switch 2  
OFF: Normal operation.  
ON: Set transparent mode. Use this setting if the X2 Multi Screen modules  
are to be used with KVM switches that are not manufactured by Adder  
Technology. Cascaded KVM switches often use special signals to set or  
identify conditions. In transparent mode, the X2 Multi Screen modules will  
pass the signals without attempting to interpret them.

ON: Transparent mode  
OFF: Normal operation  
ON: Reset LOCAL module

OFF: Microphone input on REMOTE module. Use this setting if a standard mono-  
channel microphone is connected to the MIC input on the REMOTE unit.  
4
ON: Stereo line-in input on REMOTE module. Use this setting if a stereo input is  
applied to the MIC input on the REMOTE unit.  
OFF: Microphone input mode  
ON: Stereo line-in mode

ON: Suspend operation and reset the LOCAL module. Use this setting  
momentarily to produce the same effect as removing and restoring power  
if incorrect operation has occurred. Return the switch to the OFF position  
to allow normal operation to continue.  
Note: When shipped, all switches are set in the OFF positions and this will  
produce normal operation with normal microphone input (at the REMOTE  
module).

REMOTE Switches 2 and 3  
Switches 2 and 3 determine which two keyboard keys (when pressed in unison)  
are to be designated as ‘hotkeys’. Hotkeys signal to the REMOTE module that  
the next key to be pressed is a special configuration command for the module  
and is not to be passed to the computer system.

Installation Advice  
Stage B - Mounting a module – desk or rack  
• For correct operation, the local and remote units must have ground  
connections. At the computer end, ensure that the computer or KVM switch  
that the LOCAL module is connected to has a ground connection. At the  
keyboard/monitor/mouse end, ensure that the REMOTE modules power  
supply is connected to a grounded power outlet. Alternatively, a ground  
connection will be made via the monitor, if the monitor is itself grounded.  
The X2 Multi Screen extender modules can be situated on a desk (or floor) or  
alternatively, for larger installations, mounted within optional rack mount chassis  
units.  
Desk mount  
Apply the supplied self-adhesive  
rubber feet to the underside of the  
module(s).  
Try to avoid laying the interconnect cables alongside power cables where  
possible.  
Rack mount  
Note: The module switches are not accessible once it is inserted  
into the rack, therefore, check all settings before insertion.  
1 Place the supplied rack plate onto the front of the module  
and secure it with the countersunk screws.  
WER  
2 Orient the module on its side so that its labelled face is the  
correct way up and the securing plate is facing away from the  
rack.  
PO

3 Slide the module into the required rack position. The  
rectangular cut-out in the front upper lip of the rack allows  
the screws on the modules upper edge to slide through.

Stage C - Connections  
The naming of the LOCAL and REMOTE modules relate to their proximity to  
the host computer system. Hence, the LOCAL module connects directly to the  
system (and the local peripherals), while the REMOTE is at the other end of the  
twisted pair cable and attaches to the duplicate keyboard, mouse, etc.  
Local keyboard and mouse connections  
The LOCAL module provides extra ports to accommodate a keyboard and mouse  
in the vicinity of the host system.

User arbitration and keyboard indicators  
During operation, both of the connected video monitors continuously receive  
the output from the host system. Control of the host system is arbitrated by  
the X2 Multi Screen modules on a first come, first served basis. In the idle state,  
control is available to both users and their keyboard indicators both show the  
current Num Lock, etc. conditions of the host system.

Visible image shadows  
In some installations, you may see some ‘shadows’ to the right of high contrast  
screen characters. This can be caused by an incorrectly selected sharpness setting  
and it may be necessary to make adjustments to correct this. Please see ‘Image  
controls - sharpness and brightness’ in the ‘Special configuration’ section.

Locking and unlocking the system  
In situations where the computer system (and the LOCAL module) can be  
locked away, the X2 Multi Screen modules offer a viable security system to deter  
unauthorised use. Once a password has been set, a simple key sequence allows  
the system to be quickly and securely detached from its peripherals. Only the  
correct password will reconnect the remote and local modules.  
To lock the system  
1 First set a password. For further details, please refer to the ‘Password setting’  
section in the ‘Special configuration’ chapter.  
2 Simultaneously press the currently configured hotkeys (by default,  
) along with  
and  
.
The screen will go blank and the three keyboard  
indicators will begin alternately flashing between the  
‘Num Lock’ and ‘Scroll Lock’, and ‘Caps Lock’. This  
sequence indicates that a password is required.  
To unlock the system  
1 Enter the correct password and press  
.
Note: Passwords are NOT case sensitive.  
Note: If an invalid password has been entered and the keyboard indicators  
are not flashing as described above, press to clear the incorrect attempt.  
2 If the correct password is entered, the screen will be restored and normal  
operation can continue.

Password setting  
Password override  
Password protection allows you restrict access to the system only to authorised  
personnel. A password first needs to be set and then, using the keyboard  
attached to the REMOTE module, a simple key sequence allows the system to be  
quickly and securely detached from its peripherals.  
This mode allows you to override the password that has been set at the REMOTE  
module and place it into configuration mode so that a new one may be set. This  
feature is particularly useful when passwords have been lost or forgotten.  
To override the REMOTE password

Hot plugging and mouse restoration  
To restore mouse operation when hot plugging:  
1 Carefully connect the modules to the system and its keyboard, mouse,  
monitor, audio and serial device.  
It is strongly recommended that you switch off the computer system before  
attempting to connect it via the X2 Multi Screen modules. However, if this is not  
possible then you need to ‘hot plug’ the 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 reinitialise when  
reconnected. The modules provide a feature to reinstate mouse communications  
once the necessary connections have been made.  
2 Simultaneously, press the hotkeys (by default,  
to enter configuration mode.  
and  
) along with  
3 Enter the appropriate restore function code:  
PS/2 – press  
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 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.  
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.  
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’.  
Microsoft and Logitech -specific mouse settings  
Recognising an Intellimouse-style mouse  
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.  
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.  
To change mouse signalling protocols

and  
) along with  
Before hot plugging the modules (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.

Image controls - sharpness and brightness  
To display a suitable high contrast image  
The best way to clearly view the effect of sharpness and brightness adjustments  
is to display a high contrast image, with vertical edges, on the screen.  
The X2 Multi Screen modules incorporate special controls to compensate for  
losses incurred within long cable links. Using these controls you can adjust the  
picture sharpness and brightness to improve your remote picture quality. The  
controls allow you to either affect all of the video channels collectively, or where  
losses are inconsistent, select and adjust channels individually.  
• Open a word processor, type the capital letter  
‘H’, or ‘M’ and increase the point size to 72 or  
higher. For best results, the background should  
be white and the character should be black.  
The need for image control adjustment is best discovered when viewing high  
contrast images with vertical edges, such as black lines on a white background.  
When doing so, if you notice that the screen image is ‘fuzzy’ or ‘dark’ then the  
image controls may be able to solve this condition.  
• A BLACK shadow on the right of the character  
indicates UNDER compensation.

for coarse adjustment.  
The three keyboard indicators (‘Num Lock’, ‘Caps  
Lock’ and ‘Scroll Lock’) will now begin to flash in  
sequence. The speed of the sequence indicates the  
level of the sharpness adjustment currently applied: the slower the rate, the  
lower the level of sharpness being applied.  
Note: If the monitor goes blank and switches off (due to  
oversetting the sharpness adjustment) press the Home key to  
restore.

Skew adjustment  
The twisted pair cabling supported by the X2 Multi Screen modules (category 5,  
or higher) consists of four pairs of wires per cable. Three of these pairs are used

to the slight difference in twist rate between  
these three pairs, the red, green and blue video  
signals may not arrive at precisely the same time.  
This is visible as separate colour shadows on high  
contrast screen images. This effect is particularly  
apparent when using higher screen resolutions  
and some types of category 5e cables.

In this situation, the modules provide internal  
skew adjustment that can help to rectify the  
situation. The skew adjustment works by  
delaying or advancing the timing of any of the red, green or blue colour signals  
so that they are all delivered to the monitor at precisely the same time. For best  
results a test pattern is provided and this should be displayed when using skew  
adjustment.  
The screen will show a series of fine red,  
green and blue crosses which should all be  
in line, vertically and horizontally. Skew affects the horizontal placement of  
the colours and using this pattern it is much easier to discover which, if any,  
colours are being adversely affected by the twisted pair cable run.

Flash upgrade  
Stage B - Create a startup diskette  
As part of the continual development and improvement process across the range  
of Adder products, software upgrades are occasionally made available. The  
LOCAL and REMOTE modules both contain internal flash memory and Adders  
unique keyboard-link upgrade technique allow you to utilise software upgrades  
in a straightforward manner.  
For this stage you will need a 3floppy diskette that is either blank or has  
existing contents that are no longer required. The write protect tab must be  
moved to the ‘unprotected’ position. Depending on your operating system, use  
one of the following to create a startup disk:  
To create a startup disk in Windows XP  
1 Insert a diskette into the floppy disk drive.  
Note: It is important to upgrade both the LOCAL and REMOTE modules together  
so that they are both running the same new version of software.  
2 Select ‘Start’ and then ‘My Computer’.  
Note: To upgrade the REMOTE module, a special keyboard connection cable is  
required. This cable must have 6pin mini-DIN male to 6pin mini-DIN male plugs  
with all lines connected - this is a common cable used with KVM switches.  
3 Right mouse click on the ‘3ꢀ Floppy (A:)’ icon and select ‘Format’.  
4 Check the ‘Create an MS-DOS startup disk’ box and select ‘Start’.  
To perform a flash memory upgrade, you need to perform the following stages:

problem is not listed here and you cannot resolve the issue, then please refer to  
the ‘Getting assistance’ section.  
• If the sharpness control is set too high, the monitor may not be able to  
display a picture. Try reinstating the factory default sharpness settings.  
Please refer to the ‘Image controls - sharpness and brightness’ section in the  
‘Special Configuration’ chapter.  
Temporarily disconnect the video link to the LOCAL module, connect a  
monitor directly to the computer video port and check for a correct video  
image output.  
Video image at the REMOTE module is distorted or shadows appear to  
the right of displayed objects.  
Adjustments are required to compensate for the length of the twisted pair cable  
being used. If video problems persist:  
The keyboard indicators are flashing between the Caps Lock and the  
Num Lock/Scroll Lock and the computer does not respond to any key-  
board or mouse inputs.  
• Please refer to the ‘Image controls - sharpness and brightness’ section in the  
‘Special Configuration’ chapter.  
• The modules are currently locked and require a valid password to be  
entered. Please refer to the section ‘Locking and unlocking the system’ for  
details.  
• If the overall video image is ‘fuzzy’ and/or has coloured shadows you may  
need to make skew adjustments. This procedure allows you to finely tune  
the red, green and blue video signal timings to overcome most colour  
separation problems. Please refer to the ‘Skew adjustment’ section in the  
‘Special Configuration’ chapter.  
Power is applied via the power supply but the REMOTE module opera-  
tion has stopped.  
• Each module has an internal automatic cut-out fuse to protect against  
power surges. To reset, remove power from the module for one second and  
then reconnect.  
No video image is received at the REMOTE module.  
• Check that the power/activity indicators are lit on the LOCAL and REMOTE  
modules - if they are not, then there is a power problem. The MS2 LOCAL  
module gains its power either from the computers keyboard socket or by  
using an optional power adapter. The MS4 LOCAL module requires power  
from its supplied power adapter.  
The on-screen mouse pointer does not respond to mouse movements  
• The mouse connection may have been interrupted. Either, reboot the  
system and re-power the REMOTE module power supply, or try using the  
mouse restoration command. Please refer to the ‘Hot plugging and mouse  
restoration’ section in the ‘Special Configuration’ chapter.  
When keys are pressed or the mouse is moved, check that the indicators  
flicker – if they do not respond then there could be a twisted pair link  
problem or a problem with one of the modules.  
Sound from the microphone cannot be heard or is very quiet  
• Check the setting of LOCAL switch 3 - if a microphone is connected at the  
REMOTE module, the switch should be set OFF.  
• Check that multiple link cables are correctly connected only between the  
corresponding ports on the LOCAL and REMOTE modules and do not cross  
over to other ports.  
• Check that each link cable is wired correctly as per the diagram in the ‘Skew  
adjustment’ section in the ‘Special Configuration’ chapter.  
Sound input from the stereo line input is distorted (‘tinny’ sounding) and  
only one channel is working  
• Check the setting of LOCAL switch 3 - if a stereo line input is connected at  
the REMOTE module, the switch should be set ON.  
• If possible, try using an alternative twisted pair link connection between the  
modules. Ensure that all of the link cables are of the same length and have  
the same twist characteristics - it is not possible to adjust only one video  
channel, they are all adjusted together.

cracked or broken or if you suspect that it is not operating properly.  
• If you use a power extension cord with the extenders, make sure the total  
ampere rating of the devices plugged into the extension cord do not exceed  
the cords ampere rating. Also, make sure that the total ampere rating of all  
the devices plugged into the wall outlet does not exceed the wall outlets  
ampere rating.  
• Do not attempt to service the modules yourself.  
• The modules and power supplies can get warm in operation – do not situate  
them in an enclosed space without any ventilation.  
• The modules do not provide ground isolation and should not be used for  
any applications that require ground isolation or galvanic isolation.
