Abstract
A machine that includes an electronically controlled engine provides power and communications to attached electrical devices arrayed throughout the machine via a two wire power and data bus. Sensor, driven and communication electrical devices are all connected to the direct current two wire and power data bus by a smart connector. The smart connector includes an alternating current powerline application specific integrated circuit (AC PLC ASIC) with a processor configured to communicate with an outside microprocessor via serial and peripheral interface bus communication. A memory of the AC PLC ASIC is configured to store a unique identifying address. An inductive toroid is configured to enable the AC PLC ASIC to communicate on a predetermined set of frequencies on the direct current two wire power data bus.
