Description

EXT3-21-XR-TR is a high-performance, extended-reach HDBaseT 3.0 extender for 4K60Hz (4:4:4) HDMI, USB, Ethernet, RS-232, and IR signals over twisted pair, flexibly set as transmitter-side or receiver-side device. EXT3-21-XR-TR transmitter-side converts all input signals into the transmitted HDBaseT 3.0 signal, and extends uncompressed video signals to up 100m (330ft) over CAT copper cables at up to 4K@60Hz (4:4:4) video resolution. EXT3-21-XR-TR receiver-side is an auto-switcher with HDMI and HDBaseT inputs that receives the HDBaseT 3.0 signal and converts it back into the original input signals. The connected USB 3.2 peripherals, such as a room camera and microphone, are switchable for use of the active USB host, for convenient hybrid meeting operation with both room and online participants. Manufacturer part number EXT3-21-XR-TR.
