What is the Kramer EXT3-H-R HDBaseT 3.0 receiver?

The Kramer EXT3-H-R is an HDBaseT 3.0 receiver that converts a twisted pair HDBaseT signal back to 4K@60Hz or 5K@30Hz 4:4:4 HDR HDMI, with bidirectional RS-232 and IR for display and projector control. It extends video up to 40m (130ft) over Kramer CAT cable. It is the locally powered receiver in the EXT3 family, for display locations where an outlet is already planned.

How does the Kramer EXT3-H-R work?

The EXT3-H-R accepts an HDBaseT 3.0 signal and outputs HDMI plus RS-232 and IR. Video is received uncompressed with near-zero latency at up to 18Gbps, with HDR10, HDCP 2.3, deep color, lossless audio formats, EDID and CEC passed between source and display.

It is a standard HDBaseT extender, backward compatible with other standard HDBT transmitters, and can serve as the receive-end unit for Kramer matrix switchers and switchers with integrated HDBaseT 3.0 ports. That makes it a practical display-end unit in multi-room routed systems as well as simple point-to-point links.

Bidirectional RS-232 at up to 115200 baud and bidirectional IR let a control system or remote reach the display. Status LEDs and local firmware upgrades over RS-232 simplify service, and the fanless DigiTOOLS enclosure mounts behind a display, above a ceiling or three per 1U in a rack.
