The HDMI Ultra-Slim HDBaseT + RS232 and IR over Cat Extender Box 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 is an ideal solution where HDMI video and audio need to be extnded to displays in conference rooms, classrooms, lecture halls, and many other installation needs that are far beyond the length limitations of standard HDMI cabling. This transmitter extends HDMI signals over a single 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 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. With bi-directional PoC support, one power adapter at either transmitter or receiver side can power both units, so no additional power adapter is required, 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.
