For example, the slave 2, when a starting switch, etc., are turned on, comes to be a power-up mode, a starting command signal generating means 21 transmits (t11) a signal A, starting command signal detecting means 11 of the master 1 receives this, and then, the master 1 comes to be a power-up mode after a detecting time (T11) of a starting command signal, and a response signal generating means 12 transmits a response signal B. When the slave 2 receives (t14) this by a response signal detecting means 22, immediately, the sending of the signal A is stopped and the pingpong action as the slave is executed. The master 1, after the power is increased and a constant time (T12) passes (t14), comes to be a usual master condition, data C are transmitted (t16) and the pingpong action is executed.
