The physical layer (j1939/11) describes the electrical interface to the bus. It implements a more sophisticated addressing scheme and extends the maximum packet size above 8 bytes.
Framework to work with j1939 protocol. Trucks, transit buses, excavators, construction machinery and more. For example, the engine has the source address 0x00, the steering controller has 0x13, the body controller has 0x21 and the terminal has 0x28. This address is either acquired within the address claiming procedure or set to a fixed value.
