Connecting your AdderLink DV100
Power control
IMPORTANT: Do not connect the transmitter unit, via the CATx cable, to anything other than
the receiver unit.
Low voltage power for the receiver unit is fed via the same link cable as is used for the video.
The transmitter unit always performs a check before applying power along the link cable.
The transmitter unit will disable the power if:
• The cable is disconnected, or
• Line power is overloaded.
Transmitter unit
1 Connect the plugs to the HDMI 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 transmitter unit.
Receiver unit
1 Connect the video plug to the HDMI
socket on the display screen.
2 Attach the other end of the link
cable to the socket at the end of the
receiver unit.
IMPORTANT:
• Use only screened (FTP) cable (CAT6 or better) to connect the two units.
• Do not connect the transmitter unit, via the CATx cable, to anything other than
the receiver unit.

HDMI operation
The AdderLink DV100 can support HDMI video (including 480p, 720p and 1080p) and audio up
to a maximum 165MHz clock rate.
High-bandwidth Digital Content Protection (HDCP) is supported, however, the Consumer
Electronics Control (CEC) scheme is not.
Video display (EDID) information
Extended Display Identification Data (or EDID) is an industry standard 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 rudimentary video signal.
Each time that the AdderLink DV100 units are powered on, the receiver unit attempts to read
the EDID information from the connected video display. The information is then transferred to
the transmitter unit and made available to the computer’s video adapter when required.
Cable considerations
To ensure correct operation, Category 6 (or better) shielded twisted pair cable, no longer than
50 meters in length, must be used to connect the transmitter and receiver units. The use of
shielded cables is important to maintain compliance with radio frequency energy emission
regulations and ensure a suitably high level of immunity to electromagnetic disturbances.
For best results, Adder recommends S/FTP CAT7 cable such as Adder part number VSCAT7-50.
Patch panels or cable couplers should only be used close to the transmitter unit, 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.
