The ACS2001A-R3 Multimedia (DVI-D/EDID) over CATx Single-Access Extender Kit by Black Box, comprised of a local transmitter unit and a remote receiver unit, allows you to broadcast DVI-D computer video with EDID up to 164' from the host computer over a CATx cable (CAT5 or higher). The video resolution goes up to 1280 x 1024 at 164' and 1920 x 1200 at 98.4'. DDC emulation is supported. The local unit features an "EDID copy" button for reading and remembering your monitor's EDID. Internal power protection ensures a continuous and steady video signal. The DVI-D output of your PC is connected to the local unit and your DVI-D display to the remote unit. The two units are interconnected with the CATx link cable, and each of them is powered by its own external power supply.
