ABSTRACT:
A dimming control system includes dimmer modules that receive dimming level information from one of at least two control modules. Each dimmer module includes a microprocessor that provides internal intelligence for controlling power to a load in response to dimming level information. Control modules receive industry standard protocol dimming information from various sources, convert it to dimming level information, and serially communicate the dimming level information to the dimmer modules. Dimmer modules and control modules are mounted in a rack which includes a backplane having a nonvolatile memory device that retains configuration data even if control modules are removed from the rack. An inactive control module can assume control of the rack when an active control module fails.
