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 important to maintain com-
pliance 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 local 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.

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 DV120 units are powered on, the remote unit attempts to read
the EDID information from the connected video display. The information is then transferred to
the local unit and made available to the computer’s video adapter when required.
