ADDERLink DV120 DVI Video Extender Manual

							Your AdderLink DV120 package
The AdderLink DV120 allows you to extend DVI-D digital video over a maxi\
mum of 50 meters of 
twisted pair cable with the minimum of infrastructure and fuss. It is si\
mply powered via USB from 
the local end, so that no additional power supply is required at the rem\
ote, simultaneously saving 
time and space as well as making installation very straightforward.
In addition to this brief guide, your package should contain the followi\

Regulatory information
EMC directive 2004/108/IEC
This equipment has been tested and found to comply with the limits for a\
 class A computing 
device in accordance with the specifications in the European standard \
EN55022. These limits are 
designed to provide reasonable protection against harmful interference. \
This equipment gener-
ates, uses and can radiate radio frequency energy and if not installed a\
nd used in accordance 
with the instructions may cause harmful interference to radio or televis\
ion reception. However, 
there is no guarantee that harmful interference will not occur in a part\
icular installation. If this 
equipment does cause interference to radio or television reception, whic\
h can be determined by 
turning the equipment on and off, the user is encouraged to correct the \
interference with one 
or more of the following measures: (a) Reorient or relocate the receiv\
ing antenna. (b) Increase 
the separation between the equipment and the receiver. (c) Connect the\
 equipment to an outlet 
on a circuit different from that to which the receiver is connected. (d\
) Consult the supplier or an 
experienced radio/TV technician for help.
FCC compliance statement (United States)
This equipment generates, uses and can radiate radio frequency energy an\
d if not installed 
and used properly, that is, in strict accordance with the manufacturer’\
s instructions, may cause 
interference to radio communications. It has been tested and found to co\
mply with the limits for 
a Class A computing device in accordance with the specifications in Su\
bpart J of part 15 of FCC 
rules, which are designed to provide reasonable protection against such \
interference when the 
equipment is operated in a commercial environment. Operation of this equ\
ipment in a residential 
area may cause interference, in which case the user at his own expense w\
ill be required to take 
whatever measures may be necessary to correct the interference. Changes \
or modifications not 
expressly approved by the manufacturer could void the user’s authorit\
y to operate the equipment.

External power 
adapter and USB 
adapter cable.
This power kit is only required if the host 
computer or other device with a USB 
port cannot provide sufficient power.  
Safety information
•	 For	use	in	dry,	oil	free	indoor	environments.
•	 Ensure	that	the	twisted	pair	interconnect	
cable is installed in compliance with all ap-
plicable wiring regulations. 
•	 Do	not	connect	the	interconnect	cable	to	
any other equipment, particularly network 
or telecommunications equipment.
•	 Do	not	attempt	to	service	the	units	yourself.

Connecting your AdderLink DV120
Local unit
1 Connect the plugs to the DVI-D video 
output socket and a vacant USB port on 
the computer. Note: The USB connection 
provides only power for the units. 
2 Attach one end of the link cable to the 
socket at the end of the local unit.
Remote unit
1 Connect the video plug to the DVI-D 
socket on the display screen.
2 Attach the other end of the link 
cable to the socket at the end of the 
remote unit.  
IMPORTANT: 
•	 Use	only	screened	(FTP)	cable	(CAT6	or	better)	to	connect	the	two	units.	
•	 Do	not	connect	the	local	unit,	via	the	CATx	cable,	to	anything	other	than	the 	
remote unit.
Video and USB 
connections to the 
host computer.
Video connection  
to the display 
screen.
Power control
IMPORTANT: Do not connect the local unit, via the CATx cable, to anythin\
g other than the 
remote unit. 
Low voltage power for the remote unit is fed via the same link cable as \
is used for the video. 
The local unit always performs a check before applying power along the l\
ink cable. 
The local unit will disable the power if:
•	 The	cable	is	disconnected,	or
•	 Line	power	is	overloaded.
Green LED: Flashes to 
show the unit is operating.
Yellow LED: Flashes if 
HDCP encoded content is 
present in the video feed.  
Cable considerations
To	ensure	correct	operation,	Category	6	(or	better)	shielded	twisted	pair	cable	must	be	used	to	
connect the local and remote units. The use of shielded cables is import\
ant to maintain com-
pliance with radio frequency energy emission regulations and ensure a su\
itably high level of 
immunity to electromagnetic disturbances. 
For best results, Adder recommends S/FTP CAT7 cable such as Adder part n\
umber VSCAT7-50.
Patch panels or cable couplers should only be used close to the local un\
it, connected by CAT7 
patch cables of no more than 2m in length. The overall cable run must be\
 reduced by 5m if a 
coupling is used.
DVI operation
The	AdderLink	DV120	can	support	DVI	video	up	to	a	maximum	165MHz	clock	rate	(1920	x	
1200	or	1600	x	1200	at	60Hz,	24-bit	color).
High-bandwidth Digital Content Protection (HDCP) is supported if HDMI \
or DisplayPort 
converters are used with this product.
Video display (EDID) information
Extended Display Identification Data (or EDID) is an industry standa\
rd scheme which allows 
video displays to declare their capabilities to the computer’s video \
adapter circuitry, allowing 
the	latter	to	optimize	their	outputs	accordingly.	Since	the	widespread	adoption	of	the	scheme,	
video adapters have become increasingly dependent on receiving relevant \
EDID information 
during start-up, before they will output anything more than a rudimentar\
y video signal.
Each time that the AdderLink DV120 units are powered on, the remote unit\
 attempts to read 
the EDID information from the connected video display. The information i\
s then transferred to 
the local unit and made available to the computer’s video adapter whe\
n required.
