<P>PROBLEM TO BE SOLVED: To realize communications from a CPU to a target optical data link with a configuration where a plurality of optical data links are connected to the same communication bus. <P>SOLUTION: An optical transmission apparatus 10 is provided with: a single CPU 12 for outputting a data signal in which a slave address of a device of a transmission destination is stored as destination information; a plurality of optical data links D to which one common slave address is assigned; and a selector 14 for selecting the target optical data link D. A CPU 12 outputs a clock signal and a selection signal to select the target optical data link to the selector 14, and the selector 14 outputs the clock signal only to the target optical data link on the basis of the selection signal. When the optical data link D receives the data signal and the clock signal whose destination is the same slave address as its own slave address, the optical data link D captures the data signal. <P>COPYRIGHT: (C)2003,JPO |
