Abstract

In a controller for a host machine, such as a xerographic copier, the controller function may be distributed so as to have a single master controller and a plurality of area controllers subservient thereto and communicative through an apparatus comprising a plurality of input-outputinterface system units at either of the end points of a like number of distributive links therebetween, Input sense and output data from an area controller or master controller, respectively, may be serially obtained for transmission in the communicative apparatus using the functionally identical input-outputinterface system units, either singly or collectively. Because the communicative apparatus, comprising a plurality of input-outputinterface system units and their respective distributed links, is operative to conduct almost every machine control transaction, it will act accordingly to be one of the major determinants of overall machine performance.

Because the communicative apparatus, comprising a plurality of input-~outputinterface system units and their respective distributed links, is operative to conduct almost every machine control transaction, it will act accordingly to be one of the major determinants of overall machine performance.
