Abstract

PURPOSE: To perform the effective excecution for general polling, by transmitting the hold signal to the line on which the transmitter is finished for setting, holding the receiver to be advanced to the next operation, and starting all the receivers generally after a given timing through the completion of the setting of the final line.
CONSTITUTION: The communication network NW connects the transmitter T with the receivers R0...R3, for example, and the control circuits NCUT and NCUR connect or disconnect them, and the oscillator OSC produces a given frequency at audio area as the hold signal. The transmitter T transmits the hold signal to the line on which setting is finished and holds the receiver so that it can not be advanced to the next operation, completes the setting of the final line, transmits the hold signal to the line, and starts the receivers R0...R3 generally from the predetermined operation after a given timing. Thus, general polling can efficiently be made.
