Abstract

The interface module is used with a microprocessor for calibrating the logic level and programmed selection of incoming digital data. It has a number of signal inputs and a number of signal outputs comprising a fraction of the number of inputs, with further inputs for the address bits of the data signals. A calibrating network employing diodes and resistors is connected to each signal input and a series of signal selectors each have a number of inputs coupled to the outputs from the calibrating networks. The selectors are simultaneously addressed by the address bits to allow passage of a corresp. number of calibrated signals. A voltage window detector is coupled to each signals elector and to two variable DC sources, with its output coupled to a respective signal output for the interface module.
