| Title: |
Stage Lighting Control System |
| Abstract: |
A stage lighting control system having a main processor unit and a portable
desk controller, wherein a local microprocessor is provided in the
portable desk controller to scan the dimmer control contacts in the desk
and to transmit changed state control data to the main processor as an
asynchronous serially coded signal on a low capacity link which enables
the controller to be conveniently located remote from the main processor.
Changed display data is developed by a visual display unit (V.D.U.)
interface in the main processor for transmission on the low capacity link
as standard composite video to a V.D.U. at the desk. Output to the dimmers
circuitry is through an expansible plurality of output channel processors
controlling groups of dimmers for efficient data formatting. Lighting
level information is recorded in accordance with a channel code, patching
means being provided to enable differing arrangements of dimmers circuitry
to be controlled in accordance with the recorded lighting level
information.
