HDBaseT + USB-B and RS232 TX to RX

HDMI HDBaseT + USB-B and RS232 over Cat Extender Single Gang Wall Plate Transmitter to Box Receiver - 4K 60Hz allows a 4K HDMI source to be extended up to 130ft to a 4K display using a single Cat6a Ethernet cable. This is an ideal solution where USB must also be extended alongside HDMI video and audio to interactive whiteboards and displays in conference rooms, classrooms, lecture halls, and many other installation needs far beyond the length limitations of standard HDMI cabling.
