TRANSMISSION CONTROL METHOD

摘要

PURPOSE:To improve the workability and to simplify the control operation by setting a part of designation numbers to make other parts changeable in a transmission control method where control signals are transmitted mutually. CONSTITUTION:Electrical appliances 14-16 are connected to a lighting distribution line 13 via control modules 17-19. The high-order two digits of designation number set switches 20-22 of the control modules 17-19 are fixed mechanically and the remaining 6 digits are made variable to allow each module to be identified from other modules. Thus, the designation is set by applying 6 times switching.
