    							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.
    What you may additionally need
    PSU-LPV-KIT 
    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.

    Yellow LED: Flashes when the remote unit is 
    being checked. On when the remote unit has 
    been verified and power applied to it.   
    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.
