SEQUENCE CONTROLLER

摘要

A transmitter ( 100 ) simultaneously notifies a start of providing identification codes to controlled devices ( 21 to 2 n) using a first identification code provision start signal. A delay unit ( 130 ) notifies a second identification code provision start signal to only the controlled device ( 21 ) adjacent to a controller ( 10 ). After a level detector ( 240 ) detects the first and the second identification code provision start signals, an ID provider ( 250 ) provides identification codes based on a header identification code to be provided to the self device and the number of the identification codes to be provided to the self device. A delay unit ( 230 ) sequentially notifies the second identification code provision start signal and an identification code provision end signal to the controlled device adjacently connected at a farther side from the controller than from the self device.
