<p>Each of the remote control arrangements includes momentary actuated push-button controls for independently controlling the forward, reverse and stop drive modes and the on and off lamp status of the projection appts. Each of the remote control arrangements and the local control arrangement generate or synthesize a predetermined control signal corresp. to each of the drive modes and lamp status conditions from a signal waveform inputted to the remote control arrangements from the projection appts. over one conductor of the interconnection cable. The interconnection cable includes three conductors. A first conductor carries the input signal waveform from a signal generator stage of the projection apparatus. A second conductor controls the forward, reverse and stop status of the projection appts. A third conductor controls the operational status of the projection lamp and a lamp status indicator on the remote control arrangement.</p> |
