<p>An electrohydraulic system which includes a plurality of electrohydraulic devices (12, 14) individually controlled by microprocessor-based control electronics (12a, 14a). A central controller for coordinating operation among the various devices includes a host controller (18) for providing low speed serial and/or parallel output of control signals, and a master controller (20) having a low speed serial and parallel I/O port (40, 42) for connection to the host controller (18), and a high speed serial I/O port (44) connected by a full duplex bidirectional data bus (22) in common to all of the device controllers (12a, 14a).</p> |
