<p>The method comprises providing the multipoint control system 1, wherein the multipoint control system includes a plurality of controlled units serially connected. Each of the controlled units has a execution unit and an interpretive unit; each of the interpretive units has a data processing unit and a memory unit. An information stream 2 is transmitted by a controller, wherein the information stream includes a first start packet and a plurality of first data packets, the first start packet includes a first leading message, a first address, and a first length message. The first address is modified by each of the data processing units included in each of the interpretive units according to the first leading message and transmitting to the next stage. The first data packet corresponding to the first address is retrieved 4 by each of the interpretive units according to the first address, and the first length message. Each of the execution units included in each of the interpretive units is enabled according to content of each of the first data packets. The multipoint controllers may be light emitting diode (LED) drivers or controllers. The information stream may comprise a clock signal and a data signal.</p> |
