The HD-TX-301-C-E is a surface-mountable DM Lite transmitter designed to pair with a DM Lite receiver to form a point-to-point signal extender for HDMI® signals. The DM Lite family of products offers a very simple and versatile solution for extending HD, UHD, 2K, and 4K video signals, with stereo or surround sound audio, over a single CAT5e (or better) cable. A cable length of up to 230 ft (70 m) is supported for HD 1080p, WUXGA, and 2K signals, or up to 130 ft (40 m) for UHD and 4K.

The HD-TX-301-C-E includes two HDMI inputs plus one VGA input. The VGA input is accompanied by a stereo analog audio input. Auto-switching between the HDMI and VGA inputs affords plug-and-play simplicity. Manual input selection is also available via individual buttons on the unit. The VGA input can accept RGB and component video signals by using an appropriate breakout cable or adapter (not included). The audio input is selected in tandem with the VGA input, and can be used by itself with no video source connected. It cannot be paired with the HDMI video input however.
