The HDMI + Serial RS232 over Cat allows HDMI audio/video and Serial RS232 signals to be extended over a single Cat5e, Cat6 or Cat6a cable up to 230ft at a 4K (4096 x 2160 at 30Hz, 4:4:4) resolution. This solution is compatible with any operating system and is truly plug and play with no drivers or software required. The transmitter and receiver are available in either a wall plate or box form factor and are interoperable allowing this solution to meet the needs of the installation environment. In addition, this solution utilizes TruChoice™ power, which allows power to be supplied over the Cat cable to both the transmitter and receiver from a single power adapter placed at either the transmitter or the receiver end of the solution. HDBaseT technology supports HDCP and allows the Extended Display Identification Data (EDID) signals, i.e. communication of the display’s capabilities, to pass through the extension solution ensuring that the content from the source is sent at the optimal resolution for the display. Built-in power surge protection and high ground loop immunity ensure high performance signal extension. The DB9 Serial RS232 port supports full-duplex data communication at 230Kbps and is fully compatible with all RS232 protocols. Point-to-point or multi-drop data communication is supported.
