ABSTRACT:
A marine propulsion drive-by-wire control system controls multiple marine engines, each one or more PCMs, propulsion control modules for controlling engine functions which may include steering or vessel vectoring. A helm has multiple ECUs, electronic control units, for controlling the multiple marine engines. A CAN, controller area network, bus connects the ECUs and PCMs with multiple PCM and ECU buses. The ECU buses are connected through respective isolation circuits isolating the respective ECU bus from spurious signals in another ECU bus.
