Black Box - video/audio/serial extender

Put a digital DVI screen up to 330 feet (100 m) from a video source and control a monitor via RS-232 TXD and RXD control signals with this extender. Extending over a single CAT5e/6/7 cable, the transmitter-receiver combo supports both HDTV resolutions and VESA standards. The extender makes it easy to send digital 1080p-quality video and 2-channel stereo analog audio plus serial RS-232 control signals to a distant screen or projector. Audio is integrated into the CATx cable extension, so you don't need a separate cable to transmit audio from the source to the screen. Because the extender supports bidirectional RS-232 control, you can use serial commands from a PC to control RS-232 equipment or turn a remote screen on and off to save energy in your video application. Plus, the XR DVI-D Extender with Audio, RS-232, and HDCP supports EDID and HDCP bypass, so you can also extend content from a protected-content source. Distance depends on the characteristics and quality of the cable and the type of DVI source and display.
