PURPOSE:To be in conformity with various specifications easily at a low cost and suppress the influence of noise on the receiver of a radio or the like to a low degree. CONSTITUTION:When transmit data consisting of switch data and specification data is transmitted from a main controller 1A, this transmit data is received by each of sub-controllers 1B-1D. The respective sub-controllers 1B-1D detect the switch data and specification data from the transmit data, and upon judging the obtained specification data to be different from the specification data set at present, sets the new specification data in place of the specification data set at present and acts according to this new specification data. The main controller 1A and the sub-controllers 1B-1D can be thereby used in common so as to reduce the cost and to eliminate a fitting error. |
