A remote management system where data detected by a sensor for detecting a condition of a machine is input from an input port of an interface unit of a control unit such as a microcomputer, and the interface unit is connected via a data transmission controller over a communication line with a central control apparatus which manages a machine like a washing machine from remote, and further the detected data is transmitted from the interface unit to the central control apparatus though the control unit is inapplicable to communication, while the interface unit passes the detected data of the sensor without processing and outputs the detected data to the control unit by means of setting the state of an output port thereof same as that of the input port. |
