The Hall Research HR-3P is a serial control unit that is capable of auto-detecting video on any of its three (3) video inputs and send commands to the projector. It enables commands such as select input, turn on, and more. The video inputs are VGA from a Notebook or a PC and two (2) TV-signals (Composite Video & S-Video) from DVD, VCR, Satellite Receiver, or Video Cameras. The unit includes a two-directional RS-232 serial port that you can use for programming command strings for a particular projector and then connected to the projector for control as well as normal function. The HR-3P is ideal for the automating a projector in a presentation setup.
