The TruLink® HDMI + Serial RS232 over Cat5 kit is a complete solution for extending HDMI audio/video and Serial RS232 signals over a single Cat5/Cat5e/Cat6 unshielded twisted pair cable up to 300ft at a 1920x1200 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 providing the flexibility to power at either the transmitter or receiver end. HDBaseT technology 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.
