This article describes an attachment card for an automotive test development instrument which simulates an ignition switch and other control signals for automotive-type electrical systems. Automotive electronics designers are using numerous microprocessor-based electronic units in automobiles, trucks, buses, etc., to provide control functions related to the engine, body controls, air conditioning and ventilation, remote radio and entertainment, mobile telephones, maintenance logging, navigation, etc. A microprocessor- based display system is frequently an integral part of these systems providing the control center for the driver/operator to input commands and monitor operation. Testing the display system requires duplicating or simulating the various other electronic assemblies and the operator.
