To zero the skew adjustment dials
When supplied, the two skew dials are set in 
their neutral positions. i.e. no delay to either 
of its colours. However, if the module has 
been previously used and adjusted then you 
may	need	to	relocate	the	zero	point.	There	are	
no setting markers around the two skew dials 
and the dial itself does not have a pointer.  
1	 Insert	a	small	screwdriver	into	the	skew	
dial and twist it all the way anticlockwise. 
Note the position of the dial when it 
reaches its end point.
2 Rotate the screwdriver fully clockwise and 
again note the endpoint position of the 
dial.
3 Now rotate the screw driver anticlockwise until the dial reaches the pos\
ition 
that lies midway between the two end points. This is the neutral positio\
n. 
4 Repeat this procedure for the other skew dial, if necessary.

To adjust the skew compensation
Your chances of achieving a successful skew compensation adjustment will\
 be 
improved if you do the following:
•	 Ensure	that	you	have	a	clear	view	of	one	or	both	display	screens,
•	 Display	a	suitable	RGB	test	pattern,	either	the	supplied pattern or a self-
created version,
•	 Use	a	screwdriver	of	an	appropriate	size	to	adjust	the	dials,
•	 Begin	with	both	skew	dials	in	their	neutral	positions	-	if	the	module	has	
been	previously	used	and	skew	adjusted	for	an	alternative	installation,	zero	
the	dials	as	described	in	the	section	‘To	zero	the	skew	adjustment	dials’	left.

1  Turn the SKEW RG dial clockwise or anticlockwise until you observe that the 
red and green colours are aligned. 
2 Turn the SKEW GB dial clockwise or anticlockwise until you observe that the 
green and blue colours are aligned. 
3 Your actions in step 2	may	alter	the	Red/Green	alignment.	If	so,	go	back	to	
the SKEW RG dial and turn it clockwise or anticlockwise until you observe 
that the Red and Green colours are aligned, at which point all of the co\
lours 
will be aligned.

Further information
Troubleshooting
If	you	experience	problems	when	installing	or	using	the	AdderLink	AV	modules,	
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.
No video image is received at the receiver module.
•		 Check	that	the	both	the	red	power	indicators	are	lit	on	both	the	transmitter	
and receiver modules - if they are not, then there is a power problem. B\
oth 
modules require power from their supplied power adapters.
•		 Check	that	the	green	video	input	indicators	are	lit	on	both	the	transmitter	
and receiver modules - if one or both are not lit, then a valid video in\
put 
signal is not present at the input to that module. 
•		 Check	the	link	cable(s)	that	connect	the	transmitter	and	receiver	module(s)	
for soundness and correct wiring as per the diagram in the ‘Skew 
compensation	adjustments’	section	in	the	‘Operation’	chapter.
•		 If	possible,	try	using	an	alternative	twisted	pair	link	connection	between	the	
modules. 
•		 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 
‘Adjustments’	section	in	the	‘Special	Configuration’	chapter.
•		 If	not	already	fitted,	connect	a	monitor	to	the	OUT port of the transmitter 
module and check for a correct video image output.
Video image at the receiver 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	‘Brightness	and	sharpness	adjustments’	section	in	the	
‘Operation’	chapter.
•	 If	the	overall	video	image	is	‘fuzzy’	and/or	has	coloured	shadows	you	may	
need to make skew adjustments (AdderLink AV101 receivers only). This 
procedure allows you to finely tune the red, green and blue video sign\
al 
timings to overcome most colour separation problems. Please refer to the\
 
‘Skew	compensation	adjustment’	section	in	the	‘Operation’	chapter.
Power is applied via the power supply but the module operation 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 sound can be heard on the speakers connected to the receiver  
module
•		 If	not	already	fitted,	connect	speakers	to	the	OUT port of the transmitter 
module and check for a correct audio output. 
•		 Check	that	the	both	the	red	power	indicators	are	lit	on	both	the	transmitter	
and receiver modules - if they are not, then there is a power problem. B\
oth 
modules require power from their supplied power adapters.

Safety information
•	 For	use	in	dry,	oil	free	indoor	environments	only.
•	 Do	not	use	to	link	between	buildings.
•	 Not	suitable	for	use	in	hazardous	or	explosive	environments	or	next	to	highly	
flammable materials.
•	 Ensure	that	all	twisted	pair	interconnect	cables	are	installed	in	compliance	
with all applicable wiring regulations. 
•	 Do	not	connect	the	CATx	link	interface	(RJ45	style	connector)	to	any	other	
equipment, particularly network or telecommunications equipment.
•	 Where	possible,	avoid	laying	the	twisted	pair	link	cable(s)	alongside	power	
cables. 
•	 Warning	–	the	power	adapter	contains	live	parts.
•	 No	user	serviceable	parts	are	contained	within	the	power	adapter	-	do	not	
dismantle.
•	 The	primary	means	to	cease	operation	of	the	modules	is	to	remove	the	
power adapter lead. Ensure that the power adapter is positioned near to \
the 
equipment and is easily accessible.
•	 Do	not	use	the	power	adapter	if	the	power	adapter	case	becomes	damaged,	
cracked or broken or if you suspect that it is not operating properly.
•	 Replace	the	power	adapter	with	a	manufacturer	approved	type	only.	
•	 If	you	use	a	power	extension	cable	with	the	modules,	make	sure	the	total	
ampere rating of the devices plugged into the extension cable do not exc\
eed 
the	cable’s	ampere	rating.	Also,	make	sure	that	the	total	ampere	rating	of	
all	the	devices	plugged	into	the	wall	outlet	does	not	exceed	the	wall	outlet’s	
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.
•	 Use	only	with	grounded	outlets	at	both	the	computer	and	monitor.	When	
using a backup power supply (UPS), power the computer, the monitor and\
 
the module from the same supply.
•	 For	correct	operation,	the	transmitter	and	receiver	modules	must	have	
ground connections. At the computer end, this is achieved by ensuring th\
at 
the computer that the module is connected to has a ground connection. At\
 
the audio/visual device end, this can be achieved by ensuring that the p\
ower 
supply is connected to a grounded power outlet. Alternatively, a ground \
connection will be made via the monitor, if the monitor is itself ground\
ed.
