Abstract
A data exchange system permits data transfers where both the length of the data words, and the speed of change of the information represented by the data, can both vary considerably. A central station is connected to an interface circuit, which in turn is radially connected by four-wire conductors or lines to a number of sub-units. Each sub-unit is in turn connected by a bus to a number of modules or sub-assemblies. The interface circuit contains a microcomputer and a coupler circuit. Each sub-unit contains a switching stage, a control logic circuit, and a number of shift registers.
