The Dual 4K HDMI HDBaseT + USB-C [USB 3.1 Gen2 for video], 3.5mm, and USB-B [for data] over Cat Extender Dual Gang Wall Plate Transmitter - 4K 60 Hz connects to a receiver to allow dual 4K HDMI sources to be extended up to 130ft to a 4K display using a single Cat6a Ethernet cable. This is an ideal solution where USB must be extended alongside HDMI video and audio to interactive whiteboards and displays in conference rooms, classrooms, lecture halls, and many other installation needs that are far beyond the length limitations of standard HDMI cabling. The transmitter extends HDMI, USB-C, and high speed USB 2.0 signals over a single Cat5e, Cat6 or Cat6a network patch cable. Extend dual 4K HDMI or USB-C up to 115 feet and 1080p up to 230 feet using a Cat5e or Cat6 cable. For longer 4K distances, extend 4K HDMI or USB-C up to 130 feet using a Cat6a cable. This HDMI HDBaseT transmitter is HDCP 2.2 compliant, making sure that the connection between the source and display is secure. Automatic switching is supported, connecting to the last active source. Additional analog audio input pass-through allows for audio distribution to the receiver side. High-speed USB 2.0 pass through is supported over HDBaseT up to 230ft for KVM control of devices such as USB cameras, keyboards, mice, etc. With PoH support, the receiver can send power to the wall plate, so no additional power adapter is required, allowing for greater flexibility in installations.
