Abstract: PURPOSE:To simplify the terminating system of a line by providing a switching circuit for switching the impedance at the time of a reception mode and at the time of transmission mode on plural points to be monitored which have been connected to a two-wire line. CONSTITUTION:In points to be monitored 10a-10K, switching circuits 15 are in an open state, and the impedance of the points to be monitored 10a-10K seen from a line 8 becomes a value of a high impedance 6 and exerts no influence on the line 8. When polling has been executed to the point to be monitored 10a from a monitoring point 9, the point to be monitored 10a detects a fact that the point itself has been brought to polling by a point-to-be-monitored control circuit 11, and at the time of sending back return data to the monitoring point 9, data is transmitted through a point-to-be-monitored terminal resistance 16 which has been set to a value of 1/2 of a line terminal resistance 5, and a two-wire transformer 7 by bringing the switching circuit 15 to switching control. In such a way, a terminating system of a line in each of plural points to be monitored which have been connected to a two-wire line can be simplified.
