Industrial personal computer, also known as "industrial control computer", is a computer specially designed for industrial sites. Through the bus structure, the industrial computer can detect and control the electromechanical equipment and process equipment in the industrial production process, which is the core to ensure the normal operation of industrial equipment. At present, industrial personal computers have been widely used in many fields such as control places, road and bridge toll collection, medical care, environmental protection, intelligent transportation, communication, monitoring, CNC machine tools, finance, aerospace, etc.

The DVI connector developed and produced by Cisco is a high-definition image transmission solution in a harsh industrial environment. In view of the HD image transmission requirements of industrial computers in the industrial vibration environment, the maximum refresh rate of the DVI-I connector developed and produced by Cisco is 120Hz. At the same time, the two sides of the product are equipped with screw locking structures, which can keep the connectors firmly connected. It can achieve smooth and clear picture effect for industrial personal computer under severe vibration environment.
