A signal interface circuit (10) having a terminal (14) for connection to a simulator system indicated schematically at (16), and a terminal (18) for connection to a system under test, indicated generally at (20). The simulator system may, for instance, be a PC based software simulation and the system under the test may, for instance, be an engine management system. The circuit (10) provides a reconfigurable interface between the systems (16, 20), allowing analog or digital signals to pass in either direction, in accordance with the configuration of the circuit (10). |
