The following thesis presents a method of remotely testing PC hardware under numerous conditions in both a cost effective and time efficient manner. By utilizing unique system nodes, features not available using standard hardware, such as voltage and temperature variation, may be provided. The nodes communicate using differential signalling over a RS-485 network. This method allows systems separated by large distances and varying electrical grounds to be connected. Communication with the system under test is provided using RS-232 and I2C. The node structure is expandable and allows for the addition of new test parameters and components. Although the system was designed to accommodate testing of PC hardware, its versatility provides potential testing opportunities for products not directed toward the PC market. The result is a quicker time-to-market while simultaneously enabling the creation of a more reliable product for consumers.
