Outboard motor identification number setting device and system

摘要

A vehicle can have plural propulsion devices, at least two of which include number setting sections and number transmitting/receiving sections for transmitting their identification number and receiving identification numbers of the other propulsion devices over a network. When the number transmitting/receiving sections do not receive an identification number of another propulsion device from the network for a predetermined period of time, an initial value preset in the number setting sections is set as the identification number of the propulsion device in the number setting sections. When the number transmitting/receiving sections receive an identification number of another propulsion device from the network, an identification number different from the identification number of the other propulsion device is set in the number setting sections.
