Abstract

PURPOSE:To make it possible that a slave station transmits and receives data by self-wake-up, by requesting data transmission and data receiving by self-wake-up after the set time of a timer which is started by no carrier detection. CONSTITUTION:In case that a slave station is designated from the master station to gather data, slave station designation signal generating part 2 is controlled to transmit the slave station designation signal from transmission and receiving part 4, and the receiving output signal of transmission and receiving part 7 is applied to receiving discriminating part 3 in the slave station; and if the slave station itself is designated, data transmission control part 9 is started to control data transmission from data transmission part 10. In case that the slave station transmits data by self-wake-up, timer 11 is started by the signal of no carrier detection from receiving discriminating part 8 and under the condition where data is not transmitted from data transmission part 10, and self-wake-up deciding part 12 make start of date transmission control part 9 possible to transmit data after the set time of timer 11 which has been differently set from the setting of the slave station corresponding thereto.
