Abstract

PURPOSE:To make unnecessary the count of A/D conversion time and data discrimination of address signal in the receiver, by keeping the receiver of managing center in waiting with the instruction of the transmitter of the station to be monitored during A/D conversion of analog data. CONSTITUTION:The scanning circuit 1 transmits the address (1) of the circuit 2-1 to the address line L2. The multiplexer 21 in the circuit 2-1 transmits the analog service signal ASI (2) to the ASI line L1. As a result, the address scanning in the scanning circuit 1 is stopped and the parallel-serial conversion circuit 4' transmits the data of all ''1'' or ''0'' to the control center via the MODEM 5. At the same time, the A/D converter 22 is operated. While the receiver in the control center receives the data of all ''1'' or ''0'', the waiting state is kept, allowing to avoid the discrimination of data and count of A/D conversion time.
