as an alternative to using a keypad, most projector functions can be controlled remotely, typically at a controller such as a pc, via simple bi-directional ascii messaging on an ethernet or serial communication link.

    what setup is needed? to control these projector functions remotely via ethernet and your own controller, either connect a serial link between your controller and the rs232 or rs422 port (recommended), or open an ethernet socket between your controller and the valid projector address. connect all ports, if desired.
