<p>The present invention is to provide a system connection adapter and a terminal device, which allow a function which is newly developed and added by a maker on a system A to be handled on an open system B even in the case where the system A which is an existing system for supervising and controlling such as an air conditioning apparatus and a lighting apparatus installed in a building or at home is connected with the open system B which is made up by using a protocol different from that used by the system A. This allows for ease in expanding functions. According to the system connection adapter, a conventional command, which is the original of the system A, and therefore not specified in the open system B and has no correspondence available, is added with a frame header B by a frame encapsulation and decapsulation means, and transmitted in its original form. Then, the terminal device connected on the system B is provided with the function of extracting a command A 104 from a frame B transmitted, and interpreting the command A to be processed. <IMAGE></p> |
