Product Features

  • Pixel-perfect digital video: using an uncompressed communication system with zero loss of data for resolutions up to 1920 x 1200 @ 60Hz (WUXGA)
  • Distribution up to 50m over a single CATx cable: video and power share a single cable of up to 50m (with the achievable extension distance dependent on cable type and number of connection intervals)
  • High energy efficiency: power is harvested from a standard USB socket so external PSUs are not needed
  • EDID management: Extended Display Identification Data (EDID) enables the remote system to exactly mirror the data coming from the source monitor
  • Plug and Play: AdderLink DV120 extenders are delivered in a zero config state so they work as soon as they are connected, without the need for drivers or software
  • Robust yet lightweight: tough but light ABS enclosures along with reliable internal and external connectors to withstand environmental pressures

  • CE
  • FCC


DVI-D interface: The system supports resolutions such as 480p, 720p, 1080p or WUXGA (1920 x 1200) @ 60Hz (with reduced blanking) and 24bit color depth.

Hardware compatibility: All computers with DVI-D and USB connections

Cable Guidelines

Important extension distance information

  • Recommended cables are CAT7 shielded foiled twisted pairs: Daetwyler 7702 Flexible patch cable Daetwyler 7120 Bulk cable
  • CAT6 (or better) shielded twisted pair cable must be used to connect the local and remote units in order to maintain compliance with radio frequency energy emission regulations and ensure a suitably high level of immunity to electromagnetic disturbances
  • Note: Distances are achieved using single lengths of trunk/bulk cable. For each break/patch connection reduce distance by 5m (16ft). Preferably patch cables should be of type CAT7 and less than 2m (6.5ft). Patch cables over 2m (6.5ft) must be CAT7.
Resolution Frequency Patch Connections Cable Type Distance
1920x1200 60Hz 0 CAT7 50 metres
1920x1200 60Hz 0 CAT6a (shielded) 50 metres
