Gefen today announced something it is calling the Daisy Chain HD System, which it says creates a large infrastructure for wiring displays using Cat5 cable. The system includes sender, splitter and receiver units — all interconnected in a daisy chain concept. All three units work together to extend 1080p full HD with RS232 and IR control signals using the same Cat5 cable.
Similar to a tree scenario, the system uses splitters to create new “branches.” Users can create up to ten branches, each supporting ten displays. Individual displays can be mounted next to each other or up to 100 meters apart. Source video is sent to the sender then over a single Cat5 cable to the splitter. The splitter outputs two signals: one that connects to a receiver and display; and another that connects to another splitter. Each splitter also provides one HDMI output for a local display connection. Alternatively, the Daisy Chain HD System can create a straight daisy chain to 30 displays from one splitter to the next splitter.
This new system works with all hi-def displays and video sources using HDMI supporting Blu-ray players, satellite set-top boxes and tablets. IR and RS232 controls key features of the display, including powering displays on and off and switching source inputs.
