SYSTEM AND METHOD TO PROGRAM AIR CONDITIONER MODULES

摘要

A system to program microcomputers associated with a plurality of bus rooftop air conditioners comprises a plurality of air conditioner modules located on a bus rooftop. Each air conditioner moduler includes a microcomputer. Each microcomputer is connected to a CAN (computer area network) bus connection, and the CAN bus is common to each microcomputer. The system also includes a programming device that is communicatively coupled to at least one of the microcomputers of one of the plurality of air conditioner modules, wherein the programming device transfers a software update to the at least one of the microcomputers followed by the at least one of the microcomputers transferring the software update to each of the microcomputers in the of air conditioner modules located on a bus rooftop. A method of programming a plurality of microcomputers contained within a plurality of bus air conditioning modules is also presented.
