Multiple channel, multiple scene dimming system with multiple independent remote dimmers |
摘要 |
A lighting control and dimming system utilizes a single traveler conductor for transmitting analog data signals corresponding to a particular light intensity level of multiple dimmers in 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 analog data signal and the preset binary number stored in the dimmer ROM. Dimmers enabled by the transmitted analog data signal produce a predetermined scene at a particular brightness level corresponding with one of the stored binary numbers. The remote dimmers are decoupled from a master controller by a high impedance input circuit.
