Introduction
This is a high-performance, long-reach HDBaseT extender, which can transmit HDMI™, IR, RS-232 and USB 2.0 signal to a long distance up to 100m/328ft over CAT5e/6 cable. Video resolution is up to 4K@60Hz (4:4:4). It converts the HDMI™ signal to standard HDBaseT signal and transmits it via LAN cable. It can easily control the source device or display device from the remote end through CEC and bi-directional IR signal pass-through function. It supports EDID management (COPY TV/STD) and PoC function. The Extender can be widely used in other fields such as video conference system, multimedia signal broadcasting, HDMI™ signal extension, etc
