The Dual HDMI HDBaseT + RS232 over Cat Extender Single Gang Wall Plate Transmitter - 4K 60 Hz allows a 4K HDMI source to be extended up to 130' to a 4K display using a single Cat6a Ethernet cable. This transmitter is an ideal part of an HDBaseT solution where HDMI video and audio in conference rooms, classrooms, lecture halls, and many other installation needs are far beyond the length limitations of standard HDMI cabling. This transmitter extends HDMI over a single Cat5e, Cat6, or Cat6a network patch cable. Extend 4K HDMI up to 115' and 1080p up to 230' using a Cat5e or Cat6 cable. For longer 4K distances, extend 4K HDMI up to 130' using a Cat6a cable. This HDMI HDBaseT transmitter is HDCP 2.2 compliant, making sure that the connection from the source is secure. Multi-channel audio formats are supported, including PCM 2.0/5.1/7.1, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, and DTS:X. With one-way Power over Cable (PoC) support, the transmitter gets its power from the receiver, allowing for greater flexibility in installations. Advanced users can control bi-directional IR and RS232 pass through. This HDBaseT transmitter works with C2G30015 and C2G30016 receivers.
