50 kbps Component on 250kbps J1939 Bus

Chris Litwin 5 months ago in Master modules / MC4x updated 5 months ago 2

Will connecting a 50kbps component to a 250kbps J1939 bus cause the bus to shut down. I can change the baud rate to 250kbps later, but will I even be able to send the message to change the rate? The messaging would be from a MC4x series is that matters.

Yes, if both nodes are sending the messages will collide, and the controller that is sending will go into bus-off.
