** HR-3P is discontinued and the HR-4P is recommended as a substitution for the HR-3P. **
The Model HR-3P is a serial control device that can automatically detect video on one of its 3 video inputs and issue commands to the projector (e.g. turn on, select input, etc). The video inputs are VGA from a PC or a Notebook and 2 TV-signals (Composite Video and S-Video) from VCR, DVD, Satellite Receiver, or Video Cameras. The HR-3P provides pass-through video for the S-Video and Composite Video and has a 1 in x 2 out video splitter for the VGA. The unit features a bi-directional RS-232 serial port that can be used for programming command strings for your specific projector and later connected to the projector for control and normal operation. The HR-3P is an ideal tool for the automation of a projector in a presentation setup.
