摘要： A data communication system having a master unit, an interface, and one or more remote units. The master unit includes a programmable controller having a data processor, memory storage for storing programs and command and data bytes, and address and data buses. The interface is connected to the master unit via the address and data buses, and includes a memory connected to the data bus for temporarily storing command and output data bytes from the master unit pending transmittal thereof to the remote units and for storing input data bytes from the remote units pending transfer thereof to the master unit. A first communication path, along which command and data bytes from the interface memory are transmitted to the remote units, couples the interface with the remote units. A second communication path, along which input data bytes from the remote units to the interface memory are transmitted, couples the remote units with the interface.

A plurality of secondary controllers provide input data bytes reflecting the machine status to the master controller and receive command bytes from the master controller for operating the machine components. The secondary controllers are each connected to the master controller such that corresponding data bits of the secondary controller are ORed together to provide simultaneous transmission of input data bytes from the secondary controllers to the master controller while assuring that corresponding bits of the simultaneously transmitted bytes have mutually exclusive data therein.

摘要： In a controller for a host machine such as an electrostatographic copier having a central processing unit module connected via a system bus to an input-output processing unit module, a direct memory access system functioning as part of the input-output processing unit module and operative to provide a high-speed means of refreshing and updating control registers in the host machine by direct accessing of memory in the central processing unit module. The direct memory access system may be programmed to synchronously refresh-update the host machine's control registers as in its normal mode and also asynchronously refresh-update the control registers as in the abnormal mode of a detected electrical disturbance in the electro-sensitive periphery surrounding the control registers, thus requiring restoring thereof. High-speed movement of data by the direct memory access system is achieved through dedicating a portion of random access memory in the central processing unit module for such accessing, and transferring control of the system bus from the central processing unit module to the direct memory access system. This enables data accessed through a fixed sequence of addresses from dedicated memory to be transferred directly to the host machine's control registers without incurring time constants that would otherwise be had if the data were to be manipulated by a central processor in the central processing unit module.

摘要： An electrophotographic reproduction machine for use as a copier/duplicator having a master microprogrammed controller and a plurality of area controllers cooperatively operative to carry out a plurality of machine operation tasks. At least one of the area controllers contains a separate microprogrammed controller for controlling selected tasks and devices in the reproduction machine in synchronism with the operation of other tasks as controlled by the master controller. An optical communication link couples the master and area controllers and serves to isolate the master controller from transients and a direct I/O connection.
