ABSTRACT:
In a terminal device adapted to effect transmission and receipt of information through address polling by a central monitoring/control device, an address having a predetermined number of bits is preset in a first address setter, and an address comparator compares the address of a predetermined number of bits set in the first address setter with address data sent from the central monitoring/control device. As the result of this comparison, when the address of the predetermined number of bits set in the first address setter coincides with an address sent from the central monitoring/control device, the central monitoring/control device sends a new address, and this new address is set in a second address setter with respect to the terminal device whose address has coincided. Thus, after the new address is set in the second address setter of each of the terminal devices, the terminal devices are polled by the central monitoring/control device on the basis of these new addresses.
