This transmitter/receiver kit uses ordinary, easy-to-pull CATx cable to extend DVI-D video for digital signage and other multimedia applications.
The kit provides a cost-efficient solution to overcome the 16.4-feet limitation of the DVI specification. It's particularly ideal for use in conference rooms, or in office and industrial settings.
Installation is a snap. Simply connect the DVI-D output of your PC with the local unit and your display with the remote unit. Next, connect both with the CATx link cable, and turn on the power. Use the PC exactly as if you have a direct connection to your display.
