ABSTRACT:
A controller featuring digital address display, manual control functions, signal conditioning, transducer outputs and computer address interrogation for a plurality of multi-port devices. For address interrogation the controller is compatible with a standard digital interface bus. The current device address is input to a plurality of multiplexers. The address of the device to be selected is transmitted from a computer through the interface bus to a data input/output circuit which routes the address data to a data storage unit. The address data is used to address the multiplexers to transmit to the interface bus the state of the device selected by the address data.
