<p>An apparatus connection interface (4A,4B,4C,4D) remarkably reduces the processing load of the controller. The apparatus connection interface includes a pair of connectors including a first connector and a second connector having respective signal transmission terminals for connecting a plurality of apparatuses (2A,2B,2C,2D) to be controlled in series to form an annular signal transmission line so as to circulate and transmit a condition confirming signal for confirming the condition of the apparatus to be controlled and, at the same time, circulate and transmit a condition notifying signal for notifying the condition of the individual apparatus (2A,2B,2C,2D) to be controlled by way of the formed signal transmission line.</p> |
