The evaluation kit consists of a windows-based GUI that communicates over a USB cable, to the Lumissil, LIN emulator box powered by a 12 V_DC adapter. The emulator operates as the LIN commander node and sends message frames to the IS32LT3183A LIN responder nodes over three wires. Communication is over a single wire leaving the other two wires for 12 V power and ground. In some cases, the vehicle's chassis is used as the current return path to eliminate the ground wire.
