A component navigational system comprising a video interface unit and multiple purpose-built printed circuit boards that are presented in a card cage unit. A number of the printed circuit boards will be further connected to input sensors for measuring various parameters while other printed circuit boards will be connected to specific output devices. The individual units are comprised of computer and/or electronic and/or electromechanical devices. The video interface unit provides single point access to all navigational data as well as providing a user interface for the system. The card-cage unit has multiple bus structures with a plurality of sockets for connection to a power supply, a central processing unit and the purpose built printed circuit boards. The purpose-built printed circuit boards and the central processing unit will communicate bidirectionally by means of a parallel signal bus. The central processing unit will thus be able to process input data, display appropriate information and logically control a specific output device. |
