I have an existing design I have inherited which has 3 connected J1939 Canbus networks. Network 1 connects between an engine ECU and a MC2 Controller, Network 2 connects the MC2 and a MD4 Screen and Network 3 connects between the Controller, screen, and all our other CAN Devices; Radio, etc.
What is the point of Network 2, when they are already connected through Network 3? Is it because of it being a "Multi-Master" Device?
Thanks for the help!
