Connections at each receiver module
To connect the link cable and video display
The link from the transmitter to each receiver module is made using a tw\
isted 
pair cable, specified to Category 5 or higher at a maximum length of 1\
50 metres 
(492 feet). 
NOTE: Where possible, avoid laying the twisted pair link cable(s) alon\
gside 
power cables. 
1 Attach the connector of the link cable to the socket on the receiver mod\
ule. 
There should be a click when the cable is fully inserted and locked in p\
lace.
2 Attach the VGA connector of the module to the input socket of the video \
display.
 No power input is required for the module.
 If the video image requires adjustment, please refer to the section Video 
sharpness adjustment.
IMPORTANT: The signals and power connections sent through the link 
cables are NOT compatible with standard networking equipment and 
could cause damage if connected. Do not connect the transmitter or 
receiver modules to any other devices.

Cascade connections
Where more remote video displays need to 
show the same output from the host system, 
it is possible to cascade up to three transmitter 
units to provide control for a total of up to 
twelve screens. 
Cascading these units is a simple case of 
connecting the video output of the first 
transmitter to the video input of the next one; 
with each transmitter able to drive up to four 
video displays. It is recommended that you 
cascade no more than three transmitter units 
as there will be a slight degradation in signal 
quality with each cascade link.

Video sharpness adjustment
Each receiver module has a video adjustment to control picture sharpness\
 
on the connected video display screen. 
To adjust video sharpness
1	 On	the	host	system,	display	a	suitable	high	contrast	image	(ideally	with	
one or more black vertical lines on a white background (e.g. a capital \
'H' at 72 points in a word processor).
Note: As link cable lengths increase and more receivers are cascaded, co\
lour 
separation effects may become noticeable within displayed video images, \
particularly at higher resolutions. These effects are called ‘skew’\
 and result from 
differing delays on the red, green and blue colour signals as they trave\
l to the 
receivers. If such results occur, ensure that link cables are no longer \
than they 
need to be or try using ‘low-skew’ cables. 
High contrast black character on white background
Black or bright white shadow on the right indicates the need for sharpness adjustment
3 Turn the screw fully clockwise - you should see a bright white shadow to\
 the 
right of your high contrast image 
4 Turn the screw anti-clockwise until the white shadow disappears and the \
edges of your image become sharp.    
Use a standard flatblade screwdriver to adjust the sharpness of the video image
Resetting the transmitter unit
It is possible to reset the transmitter unit either by disconnecting and\
 
reconnecting the power input or by using switch 4 of the miniature switc\
h 
block:  
2 Insert a small screwdriver into the adjustment screw on the side of the \
receiver module.

Momentarily	click	switch	4	to	the	ON	position	and	then	return	it	to	its	OFF	
position. The transmitter will reset itself.
Note: All other switches are reserved for future use and should remain O\
FF.

Operation
In operation, the AdderLink LPV modules are designed to be completely 
transparent - high quality video from the source PC system is played as \
normal, 
the only difference is that the video displays are up to 150 metres (49\
2 feet)
away. 
Indicators
Status indicators
The AdderLink LPV154T transmitter unit is equipped with two main status \
indicators adjacent to the LINK4 socket.
•	GREEN: When lit, indicates the presence of power and a video input into 
the module. If the input video is removed, power to the receiver modules\
 
will	be	cut	and	this	indicator	will	flash	to	indicate	standby	mode.	Operation	
will automatically resume once video is reinstated.
•	RED:	Flashes	while	DDC	programming	is	taking	place	(see	DDC 
information for details). If a problem occurs while attempting to harvest 
DDC information, this indicator will show a number of distinct flashes\
. Note 
the number of flashes in case you need to contact technical support, b\
ut 
otherwise retry the procedure.
Link indicators
Additionally, the AdderLink LPV154T transmitter unit features two indica\
tors per 
link socket.
•	GREEN: When lit, indicates that power and video are being supplied to the 
receiver module.
•	YELLOW:	Flashes	if	the	link	cable	is	disconnected	or	if	line	power	is	
overloaded.

Further information
Troubleshooting
If you experience problems when installing or using the AdderLink LPV mo\
dules, 
please check through this section for a possible solution. If your probl\
em is not 
listed here and you cannot resolve the issue, then please refer to the ‘\
Getting 
assistance’ section.
No video image is received at the receiver module.
•		 Check	that	the	green	status	indicator	(adjacent	to	the	LINK 4 socket) is lit on 
the transmitter unit. If it is not then there is a power or video input \
problem. 
If the green status indicator is flashing then there is no input video\
, possibly 
because the host system has gone into standby; or simply that the input \
cable is not correctly connected. The transmitter unit requires power fr\
om its 
supplied power adapter.
•		 Check	the	link	cable(s)	that	connect	the	transmitter	and	receiver	module(s)	
for soundness. If possible, try using an alternative twisted pair link 
connection between the modules. 
•	 Check	the	yellow	indicator	on	the	associated	link	socket.	If	the	yellow	
indicator is flashing continuously, check that the corresponding recei\
ver is 
properly connected. 
 Alternatively, this output may have been overloaded. Disconnect the cabl\
e 
and reconnect it to check. 
 Note: The yellow indicators for all unused link ports will flash.
•		 If	the	sharpness	control	is	set	too	high,	the	monitor	may	not	be	able	to	
display a picture. Try reducing the sharpness setting. Please refer to t\
he 
Video sharpness adjustment section.
•		 If	not	already	fitted,	connect	a	monitor	to	the	 port of the transmitter 
module and check for a correct video image output.
•		 Check	that	all	of	the	miniature	configuration	switches	are	in	the	OFF	
position during normal operation. 
Power is applied via the power supply but the transmitter module  
operation has stopped.
•		 The	transmitter	unit	has	an	internal	automatic	cut-out	fuse	to	protect	
against power surges. To reset, remove power from the transmitter for on\
e 
second and then reconnect.
