The LIN, for Local Interconnect Network, is a recent communication bus used by the automotive industry, usually as a sub network of the CAN bus network, to connect microactuators and sensors. It works with 1 master and up to 16 slaves with a speed of 19.2 Kbps for 40 meters in length.

CAN, for Controller Area Network, is a serial bus used for communication between computers in the automotive, aerospace and telecomunication among others. Two message standards exist: the CAN 2.0A with a 11-bit addressing and CAN 2.0B with a 29-bit addressing. The recommended rates are 20Kbits/s to 1Mbits/s (depending on the capacitance and therefore also the distance: respectively 1,200 meters and 60 meters).

Electronic Control Modules are subsystems consisting of CPUs and assorted signal inputs and outputs dedicated to controlling a component within the vehicle (cars, trucks...). The aim of this system is to check that all ECM actions are correct, conforming to the specifications. It performs design validation. It is a development bench, helping technicians and developers during design and developement phases. System Diagram
