Switching center for use in e.g. twin printing system, has crossbar switch that is formed in such a way that when passing through center run time difference of signals of data is not developed, where center is electronically switchable

摘要

The center has a field program gate array in which a state machine is operated. A crossbar switch is formed in such a way that when passing through the switching center additional run time difference of the signals of the data is not developed. The center is electronically switchable. Multiplexer groups (54a, 54b, 54c) are switched by a switch conductor for optionally connecting input connectors with output connectors and data lines.
