ABSTRACT:
Equal-length group data obtained by grouping together slot pairs connected by a wiring pattern of equal length is stored in advance. Error rate is determined while changing a pre-emphasis (PE) setting value and an equalizer (EQ) setting value of a signal transmitted between a specified slot pair. The slot pairs belonging to the same equal-length group as the specified slot pair are selected based on the equal-length group data, and optimum PE and EQ setting values, determined based on the error rate, are set for the signals transmitted between the selected slot pairs.
