The VOPEX® VGA Video Splitter/Extender simultaneously broadcasts high-resolution VGA video from one computer to 4 or 8 remote monitors located up to 1,000 feet away using CAT5/5e/6 cable. Audio can be broadcasted to self-powered stereo speakers at the local unit and each remote location when using NTI's remote units with audio option. The VOPEX VGA Video splitter/extender system has two components: the VOPEX-C5V(A)-xC1000 VGA broadcast unit, which connects to the host computer and also supplies video to a local monitor, and an XTENDEX® remote unit (ST-C5V(2A)-R-1000SP or ST-C5V(A)-R-600) for each remote monitor. The units are interconnected by CAT5/5e/6 cable. For more information, visit http://www.networktechinc.com/vga-splitter-cat5.html
