処理装置の伝送路インタフエース方式。[Claims for Utility Model Registration] In a data processing device in which two or more data processing modules are connected via a loop transmission line via a bus adapter and transmit data to each other, It has a first bus adapter that connects the cable and the coaxial cable on the loop transmission line side, and a first converter that converts an optical signal or electrical signal into an electrical signal or optical signal, and serves as an input/output interface of the data processing module. A second bus adapter connects a coaxial cable for use with a fiber optic cable on the loop transmission line side via a first converter, and a second converter converts an optical signal into an electrical signal, and performs data processing. A third bus adapter connects the coaxial cable for the module's output interface with the coaxial cable on the transmission line side, and connects the coaxial cable for the input interface via a second converter, and converts the electrical signal into an optical signal. The coaxial cable for the output interface of the data processing module is connected to the optical fiber cable on the transmission path side via the third converter, and the coaxial cable for the input interface is transmitted. A transmission line interface for a data processing device, characterized in that a fourth bus adapter is provided to connect to a roadside coaxial cable, and the first, second, third, or fourth bus adapter is selected depending on the transmission distance. Ace method.
