The HDMI HDBaseT + VGA, 3.5mm, and USB-B to A over Cat Extender Dual 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 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, VGA, Stereo Audio, and high speed USB 2.0 signals over a single Cat5e, Cat6 or Cat6a network patch cable. Extend 4K HDMI up to 115 feet and 1080p VGA up to 230 feet using a Cat5e or Cat6 cable. For longer 4K distances, extend 4K HDMI up to 130 feet using a Cat6a cable. This HDMI HDBaseT Extender is HDCP 2.2 compliant, making sure that the connection between the source and display is secure. Automatic switching is supported by the transmitter, connecting to the last active source. One-way analog audio pass through is supported from the transmitter to the receiver. 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 transmitter, so no additional power adapter is required, allowing for greater flexibility in installations. Support this HDBaseT system that is already deployed in the field by upgrading firmware through the Micro-USB port on front panel of the wall plate transmitter, and upgrade the firmware through the RS232 port on rear panel of the receiver.
