Image controls - sharpness and brightness (continued)
To use the image controls
1 Simultaneously, press the hotkeys (by default,  
and ) along with  to enter configuration 
mode.
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.
2 [OPTIONAL STEP] By default, your sharpness and brightness adjustments ar\
e 
applied equally to all of the video channels. However, if required, you \
can 
select individual channels and adjust them separately.    
 To select video channels: Using the numeric keys of the main keyboard (not 
the keypad keys), press the number of the video channel to adjust. When\
 a 
numeric key is pressed, all three of the keyboard indicators will illumi\
nate for 
a moment before continuing with their flashing sequence.   
3 While viewing the displayed high contrast screen image, use the followin\
g 
keys to adjust the controls:
Sharpness:   for fine adjustment,   for coarse adjustment.
     There are 255 sharpness levels (one coarse step jumps 10 levels).
  To autoset sharpness: Press    to make the module calculate   
 and apply an automatic compensation level - you can use this as a  
 starting point for your fine tuning.
Note: If the monitor goes blank and switches off (due to 
oversetting the sharpness adjustment) press the Home key to 
restore.
Brightness:   for adjustment. There are 255 brightness levels.

Exit image controls and save settings 
4 When no shadows are visible and the displayed images on all video channe\
ls 
have crisp edges, press  to exit configuration mode and permanently save 
all settings.
The new compensation settings will be stored, even when power is removed\
 
or if a complete reset is initiated. These settings should not require f\
urther 
changes unless the cabling arrangements are altered. 
To reset all image controls to their default states
1 Enter configuration mode (if you are already in image control mode, p\
ress 
the  key to ensure that all channels are selected).
2 Press the Home key
3 Press  to exit configuration mode. 
Re-select all channels Select video channel 1 
Select video channel 3 (MS4 model only) 
Select video channel 2 
Select video channel 4 (MS4 model only) 
Note: Use the main keyboard 
numeric keys, NOT the keypad 
keys on the right hand side.
If the image controls cannot provide a crisp image
If, after adjusting the image controls, one or more screen images 
remain fuzzy or have coloured shadows you may need to use the 
Skew adjustment feature. Please see the next section for details.
 Note: When entering configuration mode, all video channels are 
automatically selected. You can change the video channel at any time.

Skew adjustment
The twisted pair cabling supported by the X2 Multi Screen modules (category 5, 
or higher) consists of four pairs of cables. Three of these pairs are u\
sed by the 
modules to convey red, green and blue video 
signals to the remote video monitor. Due 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 generator is available free of charge from t\
he Adder 
website (see right) and this should be displayed when using skew adjus\
tment.
See next page for skew adjustment details        
The Adder test pattern generator showing its RGB crosses. In this case, the green signal can be seen out of line with the other two colours.

To use skew adjustment
1 Display the test pattern. See To obtain and run the free Adder test 
pattern generator.     
 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.  
2 Simultaneously, press the hotkeys (by default,  and ) along  
with  to enter configuration mode.
The three keyboard indicators (‘Num Lock’, ‘Caps 
Lock’ and ‘Scroll Lock’) will now begin to flash in 
sequence.     
4 Press the  and  keys to retard or advance the timing of the selected 
colour channel respectively. On screen you will see a change in the posi\

6 If required, repeat steps 4 to 6 to select and adjust any colour channel\
 until 
the vertical lines of the red, green and blue crosses are all aligned.
7 When all colours are correctly aligned, press  to exit configuration mode 
and permanently save all settings.
Note: Once you have made a skew adjustment, it may be necessary to re-
adjust the image controls to attain an optimum screen image.        
3 As appropriate, press either the R, G or B keyboard keys to select 
the appropriate colour channel. Corresponding keyboard 
indicators will flash rapidly to show which channel is 
currently selected for adjustment: Num Lock for Red, 
Caps Lock for Green and Scroll Lock for Blue.

Further information
Troubleshooting
If you experience problems when installing or using the X2 Multi Screen \
modules, please check through this section for a possible solution. If y\
our 
problem is not listed here and you cannot resolve the issue, then please\
 refer to 
the ‘Getting assistance’ section.
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 pai\
r cable 
being used. If video problems persist:
•	 Please	refer	to	the	‘Image	controls	-	sharpness	and	brightness’	section	in	the	
‘Special Configuration’ chapter.
•	 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 tun\
e 
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.
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 computer’s keyboard socket or \
by 
using an optional power adapter. The MS4 LOCAL module requires power 
from its supplied power adapter. 
 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.
•		 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.
•		 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 h\
ave 
the same twist characteristics - it is not possible to adjust only one v\
ideo 
channel, they are all adjusted together.
•		 If	the	sharpness	control	is	set	too	high,	the	monitor	may	not	be	able	to	
display a picture. Try reinstating the factory default sharpness setting\
s. 
Please refer to the ‘Image controls - sharpness and brightness’ se\
ction 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 vide\
o 
image output.
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.
•	 The	modules	are	currently	locked	and	require	a	valid	password	to	be	
entered. Please refer to the section ‘Locking and unlocking the syste\
m’ for 
details. 
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.
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 mous\
e 
restoration’ section in the ‘Special Configuration’ chapter.
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.
Sound input from the stereo line input is distorted (‘tinny’ soun\
ding) 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.

Emissions and Immunity
A Category 5 (or better) twisted pair cable must be used to connect th\
e X2 
modules in order to maintain compliance with radio frequency energy emis\
sion 
regulations and ensure a suitably high level of immunity to electromagne\
tic 
disturbances.
All other interface cables used with this equipment must be shielded in \
order 
to maintain compliance with radio frequency energy emission regulations \
and 
ensure a suitably high level of immunity to electromagnetic disturbances\
.
The extender does not provide any extra error checking on the RS232 seri\
al port 
signals and so to ensure a suitably high level of immunity in electrical\
ly noisy 
installations, an RS232 protocol with bit error correction or a shielded\
 CATx 
cable should be used.
