| Title: |
Dimming Control System with Distributed Command Processing |
| Abstract: |
A dimming control system includes a non-volatile memory mounted to a
backplane in a rack having a control module slot for receiving a control
module, and a plurality of dimmer module slots for receiving dimmer
modules. The non-volatile memory stores operational information for the
rack, and the control module can be removed from the rack without
affecting the information stored in the nonvolatile memory. The
non-volatile memory is adapted to store looks which can be invoked by the
rack without external control. The rack includes a pull-out tray for
receiving the control module, and the pull-out tray includes a back wall
which functions as the backplane. The non-volatile memory can be
programmed through the control module by a computer or a hand-held
controller coupled to the control module. The hand-held controller
includes a display and can provide local control of the rack. When the
hand-held controller is mounted in a carrier on the front door of the
rack, the display is visible through a viewing window in the door.
