Automatic Baud Rate Detection Process
J1939/16_201811
Define a process enabling devices to detect the baud rate of a SAE J1939-11, SAE J1939-14, or SAE J1939-15 network automatically with the intent of minimizing or eliminating communication disruption between existing devices. These networks only support CBFF and CEFF Data Frames, as defined in ISO 11898-1.
Rationale:
This version was created for the following reasons:
-
Addresses an issue where systems would not be able to detect the baud rate if the CAN hardware used performed differently in Listen Only Mode than described in the previous version of this document.
-
Guidance for performing baud rate detection based on ECU Network Initialization.
