The BHDBT-R-SI HDBaseT Class B(HDBaseT-Lite) HDMI over Cat5e/6/6a Extender Receiver works in tandem with the Tripp Lite BHDBT-Series matrix transmitter in your HDBaseT Class B installation to extend uncompressed HDMI video and audio, RS-232 serial and IR remote control signals. Using a single Cat5e/6/6a cable, the BHDBT-R-SI can extend an HD 1920 x 1080(1080p) signal up to 230 feet(70 m) or an Ultra High Definition(UHD) 3840 x 2160(4K x 2K) video signal up to 130 feet(40 m). To further extend and expand your installation, you can insert up to five BHDBT-TR-SI Extender Transceivers between the receiver and transmitter for a total range up to 780 feet(4K x 2K) or 1,380 feet(1080p) with a monitor connected to each transceiver.You can control RS-232 serial devices, such as touchscreen displays or scanners, at baud rates up to 115 Kbps. The 2-way IR Remote Control feature(@ 39 KHz) lets you control your Blu-ray player using its remote when at the remote monitor and vice versa. The monitor connects to the rear locking HDMI port(ideal for use with Tripp Lite's P569-006-LOCK High-Speed HDMI cables with locking connectors) that prevents the cable from coming loose or undone, ensuring an intact signal.The BHDBT-R-SI supports 7.1-channel surround sound, DTS-HD and Dolby TrueHD audio, as well as 3D video, EDID and HDCP. Included mounting hardware lets you attach the receiver to a wall, rack or pole. Sets up quickly with no software to download or install.
