The faults must be inserted by software and by microswitches. The module must be provided with a EISA BUS 31+18 interface for connection to power supply and with a software able to allow the study of theoretical topics through PC with hyper textual navigation according to the HTML standard. Connections and test points by 2mm terminals.
