SAE J1939/16_201510

Define a process enabling devices to detect the baud rate of a network automatically with the intent of minimizing or eliminating communication disruption between existing devices. This is the first version of the document. The purpose of this document is to establish a common method of automatically detecting the baud rate of an SAE J1939 network. This is needed so manufacturers that provide devices capable of operating on SAE J1939 networks with different baud rates can reliably detect the baud rate of that network segment without interrupting network communications.
