To enhance flexibility of layout in machine and reduce its cost in a communication control system, in which a logic signal transmitted from a machine control unit is modulated so that an analog signal is generated and radiated as electric waves and the received analog signal as electric waves is demodulated so that a logic signal is generated and transmitted to the machine control unit.
The communication control system includes a main board 51 for mounting a CPU 10; an RF control circuit board 52 for mounting a non-contact transmission logic IC 20, which generates a logic signal, in relation to the data transmitted from the main board 51; an RF transmitting and receiving circuit 30 for modulating the logic signal transmitted from the RF control board 52 and generating an analog signal; an antenna board 53 for mounting an antenna 40, which radiates the generated analog signal as electric waves; and harnesses 54, 55 for connecting between each board and transmitting the logic signal.
