PROBLEM TO BE SOLVED: To solve the following problems: when backplane transmission is replaced with optical-fiber transmission, there is no compatibility with backplane transmission using an electric cable, and on the other hand, when the electric cable is used for the backplane transmission, intensity of waveform correction cannot be adjusted.SOLUTION: A waveform correction circuit is mounted in a connector on the backplane side to ensure signal quality of an electric signal. In addition, a correction amount of the waveform correction circuit can be adjusted by a command and a level signal even after the waveform correction circuit is mounted. When the backplane transmission employs light instead of electricity, it is attainable by changing only a transmission cable or only a part of a section constituting the backplane transmission. |
