The Dual 4K HDMI HDBaseT + VGA, 3.5mm, and RS232 over Cat Switching Extender Box Transmitter - 4K 60 Hz allows 4K HDMI or VGA sources to be extended using a single Cat6a Ethernet cable. This is an ideal solution where video and audio needs to be extended to displays in conference rooms, classrooms, lecture halls, and many other installation needs that are far beyond the length limitations of standard cabling. This transmitter extends HDMI and VGA signals over a single network patch cable. Extend 4K HDMI up to 115' and 1080p VGA up to 230' using a Cat5e or Cat6 cable. For longer 4K distances, extend 4K HDMI or 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. The transmitter supports PoC PD to receive power from an HDBaseT receiver with PSE module. It can also be powered by local 12V power supply and share power with the receiver via the 3-pin phoenix power out connector, so no additional power adapter is required, allowing for greater flexibility in installations. Advanced users can control IR and RS232 pass through. This HDBaseT transmitter works with C2G30015 and C2G30016 receivers.
