HE02N is a 4K HDMI over HDBaseT extender that uses a single Ethernet cable to extend uncompressed HDMI with resolution up to 4K@60Hz 4:2:0, and transmission distance up to 100M, along with bi-directional IR and RS232 signals. The extender also supports HDMI ARC (Audio Return Channel) designed to reduce the number of cables between your TV and the amplifier. And a built-in Ethernet port with 10/100 bandwidth on both TX and RX sides allows the HE02N to connect with standard network devices such as 100Base-T routers, TVs, and computers.
