Abstract

PURPOSE:To increase rate detection accuracy by assigning rate-detecting character assembling circuits corresponding to respective rate classes, and also to widen the detectable range of a rate by making it possible to use any rate detecting characteristic. CONSTITUTION:The the same circuit, one or one start-stop data terminal or more is connected which has one or one data communication rate or more, and the data communication system is equipped with one or one circuit of this kind or more. In this system, data-communication-rate detecting character codes are assigned to circuit-corresponding character assembling circuits 410 to 41n corresponding to data communication rates. Further, this system is provided with rate detection circuit 3 equipped with rate-detecting character assembling circuits 31 to 33 which function to compose and decompose characters as a preset data communication rate; under the controll of control part 1, circuit corresponding part 4 is selected by circuit selector circuit 44 and then connected to circuit 3 in order to apply the outputs of circuits 31 to 33 to receiving clock line selectors 431 to 43n of circuit corresponding part 4 through rate discrimination circuit 35, and by the outputs, character codes of circuits 410 to 41n are selected and outputted.
