4-port VGA, Component A/V, Stereo Audio, RS-232, and IR Splitter-Extender unit; sends signals to four output devices up to 1000 ft away over CAT5.


Use Cat5 Cabling to Broadcast High-Resolution Component Video, Stereo Audio, RS-232 and Infrared to Four Stations up to 1,000 Feet Away


Smart-AVI’s HDC-400 allows for the extension and distribution of high-definition video, stereo audio, infrared, and RS-232 signals to as many as four separate locations using inexpensive Cat5 cabling as far as 1,000 feet away.

Using RS-232 communication, users can send commands to single or multiple devices that are connected to the HDC-400, including volume adjustment, channel selection or power the display panel on/off remotely. This solution is perfect for venues such as sports bars, retail shops, command posts, or even educational/corporate training facilities where multiple screens may be necessary for adequate viewing of high-definition content.
