PROBLEM TO BE SOLVED: To solve the following problem: it is difficult to apply a conventional data communication system to a case where a wide wiring space can not be secured, since circuit boards are connected to a control substrate in parallel with each other and N pieces of wiring are required between a driving device and a control device. SOLUTION: In a data communication system according to the present invention, first to N-th circuit boards 1-n are connected in series in order within a driving device, the N-th circuit board (n) is connected to a control substrate 21 of a control device 20 and within one frame of a transmission signal 13 to be transmitted from the first circuit board 1 through the second to N-th circuit boards 2-n to the control substrate, first to N-th data 13a-13n are superimposed in order which are created by the circuit boards 1-n, respectively.
