PURPOSE:To display a communication result and to act for a terminal function and to simplify the control and maintenance of the whole system by providing a center unit with a function for test communication. CONSTITUTION:The on/off information of a switch contact and other analog information are applied and stored to/in a transmitting terminal 3N to transmit these information to a receiving terminal 4N through a transmission line. Receiving the information, the terminal 4N outputs the information from an output terminal and applies it a connected apparatus. Thus, a remote motor is started and stopped by turning on/off a relay to light up a lamp. |
