Abstract

PURPOSE:To realize a successive transmission of data to the central unit from the line of a system without setting the address to each terminal unit, by including the specific code into the data and then calling the terminal units successively. CONSTITUTION:The terminal units 2A and 2B connected to the central unit 1 includes the decoder 3 which detects the specific code and the encoder 5 which transmits the data contents shown by the data sources 7A and 7B when the counter 4 counting the output signals of the decoder 3 counts the set value. Then the set value of the counter 4 is made different successively at the units 2A and 2B each, and at the same time the specific code is included into the data sent from the encoder 5. Thus the prescribed signal is delivered first from the unit 1 to call the units 2A and 2B successively.
