Abstract

An analytical system capable of analyzing data by means of an analytical machine or tool and providing that analytical data to a computer for processing is provided. A protocol conversion radio machine is provided corresponding to each analytical machine and tool to be controlled and data can be communicated in a wireless manner between the analytical machine and tool and a plurality of computers. The protocol conversion radio machines cannot only mutually communicate with the plurality of computers but also can give and receive control signals to assist in the accumulation and transmission of analytical data between the computers and the analytical machines and tools.

Claims
