p.40

The article discusses the design principles for the multichannel distributed system for the synchronous data acquisition utilizing the Ethernet technologies in the hard real-time conditions, with emphasis on the methods for compensating the time delay and synchronizing the data takeoff from a great many sources. The system is intended for use as a part of the marine equipment, but its design principles are universal, and they can be employed in variety of industrial applications.
