Abstract

A distributed networking system and protocol is provided to a networking system with a modular design. The distributed networking system may include a networking system, modules, control module, user interface module, input/output module, network module, data transmission network, hybrid modules and composite modules. A method to interface with accessories of a system with a modular design using the distributed networking system and protocol is also provided.
