Perfect digital video, real time control

The system is uncompressed, where by every pixel of every frame are sent without loss. The receiver supports DisplayPort Dual Mode (DP++) which means that monitors which only support HDMI or DVI can be used (with the correct adapter cable).

Dsiplayport and thunderbolt display resolutions

Single CATx cable

Video, USB 2.0 (HID-only) and audio all pass along a single cable. A second CATx cable is required for the Hi-Speed USB 2.0 extension.

Up to 150 meter extension distances

Distance is dependent on the monitor resolution, number of monitors, cable type and the number of connection breaks for patch panels and wall plates. See table on reverse for details.

USB 2.0

Enables connection of any USB human interface device from mice and keyboards through to graphics tablets, jog shuttles, joysticks and 3D explorers. Mass storage devices and isochronous devices such as webcams and headsets can be used through the transparent USB 2.0 Hi-Speed port.

EDID management

The system has intelligent EDID management to allow the true characteristics of the monitor to be passed back to the computer.

Plug and play

The AdderLink XD522 extender is delivered in a zero config state so you can plug the units in and start working with them straight away. There is no need for drivers or software to be installed.

Digital audio

Important Extension distance Information

Recommended cables are CAT7 shielded foiled twisted pairs:
Daetwyler 7702                 Flexible patch cable
Daetwyler 7120                 Bulk cable


Resolution Cable Type Patch connections Distance
2560×1600@60Hz or two 1920×1080@60Hz CAT7 Bulk (trunk) 0 100 metres
2560×1600@60Hz CAT7 Patch 2 80 metres
2560×1600@60Hz CAT6a 2 70 metres
2560×1600@60Hz CAT5e 2 60 metres
Single 1920×1080@60Hz CAT5e 2 150 metres


Distances are achieved using single lengths of trunk/bulk cable with two 3 meter CAT7a patch cables. For each additional break/patch connection reduce distance by 5 meters. Preferably patch cables should be of type CAT7a and less than 2 meters. Patch cables over 2 meters must be CAT7a.
