Dual Link resolutions, Real Time Control

The X-DVI PRO DL allows you to remote your monitor with resolutions up to 2560x1600 @60Hz up to 50 meters away from your computer. Using a visually lossless technique, no visible artefacts or latency are introduced allowing you to be certain of quality and control.

50 meters over a single CATx cable 

Video, USB 2.0 (low and full speed) and audio pass along a single cable, providing up to 50 meters of extension. 

Distance is dependent upon video resolution, CATx 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 human interface device from mice and keyboards through to graphics tablets, jog shuttles, joysticks, 3D explorers and mass storage devices. Full speed (12 Mbps) isochronous devices are also supported.

Power efficiency

The X-DVI PRO DL extender is designed to be highly power efficient and consumes <6 watts per point.

EDID management

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

Important extension distance details

Recommended cables are CAT7 shielded foiled twisted pairs:

Daetwyler 7702 Flexible patch cable 
Daetwyler 7120 Bulk cable

Category 5e (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.

Resolution Cable Type Patch Connections
Total Distance
2560 x 1600 @ 60Hz CAT7 0 50 meters
2560 x 1600 @ 60Hz CAT6a (shielded) 0 50 meters
2560 x 1600 @ 60Hz CAT5a (shielded) 0 50meters
2560 x 1600 @ 60Hz CAT7 2 40 meters

Note: Distances are achieved using single lengths of trunk/bulk cable. For each break/patch connection, reduce distance by 5m. Preferably patch cables should be of type CAT7a and less than 2m. Patch cables over 2m must be CAT7a. The maximum extension distance for USB is 50m including connections to and from the X-DVI PRO independent of cable type. If a USB hub is connected to the RX unit, this is seen as 5m of cable length. This needs to be taken into consideration when planning your system.
