We have a device that support SAE J1939 interface and having issue with finding out how to communicate with. Can someone point the direction. Thanks
SAE J1939 defines five layers in the 7-layer OSI network model,and this includes the CAN 2.0b specification (using only the 29-bit/"extended" identifier) for the physical and data-link layers. Under J1939/11 and J1939/15 the baud rate is specified as 250 kbit/s, with J1939/14 specifing 500 kbit/s. The session and presentation layers are not part of the specification.
I would start by looking for an adapter. This would allow you to then say use a Serial or parallel port connection and poll the device at a specfic band rate.
