MULIPLEX TRANSMITTER

摘要

PURPOSE:To effectively reduce a dark current by appropriately shifting each communication node into a wake-up state. CONSTITUTION:In this multiplex transmitter having plural communication nodes 1 connected through a multiplex bus 5, each communication node 1 is respectively provided with a signal output means 21 for outputting a wake-up signal to shift the communication node 1 into the wake-up state corresponding to the operation of an input switch 6 and an operating command signal to operate electrical equipments and a starting means 23 for changing the communication node from a sleep state to the wake-up state corresponding to the wake-up signal outputted from this signal output means 21, and an output interval between the wake-up signal and the operating command signal outputted from the signal output means 21 is set a little longer than the wake-up starting time of the communication node 1.
