ABSTRACT:
A lighting control and dimming system utilizes a single traveler conductor for transmitting analog data signals corresponding to a particular light intensity level of a dimmer group. A predetermined binary data word is retrieved from the read-only memory of a remote controller, and is transmitted serially in an analog pulse train over the traveler conductor to each dimmer unit. Each dimmer unit includes a microcontroller and read-only memory in which a group of binary numbers are stored. The analog data signal received by each dimmer is converted to binary and is compared bit-by-bit with each binary number stored in the dimmer memory. A serial bit comparator produces an enable signal in response to a bit-by-bit identity match between the converted analogy data signal and the preset binary number stored in the dimmer ROM. All the dimmers are enabled by the transmitted analog data signal, thus producing a predetermined scene at a particular brightness level corresponding with one of the stored binary numbers.
