<p>Transition status information on a status transition occurring in transmission-side unit is transmitted serially to a reception-side unit in data communication among units constitution a device. The reception-side unit reproduces a status control signal always after a predetermined delay time from the occurrence. Therefore, the status control signal can be transmitted serially without any time skew. Even if a control command signal is transmitted together with the status control signal through serial communication between the transmission- and reception-side units, a transition status information is detected from the received signal by adding identification information to the transmission information.</p> |
