Abstract

PURPOSE:To enable to mount interfaces having different types of electric characteristics in the same module, by changing over the interface circuits having different types of electric characteristics through the provision of change-over switches. CONSTITUTION:Either one of the first and second receiver circuits is selected for a reception interface signal L1 with a selector switch S1. Further, either one of the output of the receiver circuits 1 or 2 is selected by a selector switch S2 as an input signal L6.
