Abstract:

A console terminal arrangement is disclosed for use in connection with a fault-tolerant computer system including a plurality of processing modules, at least some of the processing modules including an operator input/output interface for receiving operator input from an operator input device and operator display output on an operator display device. The console terminal arrangement facilitates management of all of the processing modules by a single operator from a single location. The arrangement includes a console terminal and a plurality of processing module interfaces interconnected by a network. The console terminal includes an operator input device and an operator display device, and generates operator input messages including processing module management information generated by the operator input device in response to inputs provided by an operator and an address identifying one of the processing modules to be managed by the console terminal. The console terminal further generates and displays video images in response to video image data received in messages from the processing modules. Each processing module interface receives operator input messages generated by the console terminal which include an address identifying the processing module connected to the processing module interface and provide the processing module management information to the operator input/output interface to control the processing module.

Abstract:

A keyboard bus is provided in a PC for connecting a peripheral such as a keyboard to a central unit, serially through external modules coupled to the bus enabling communication with the central unit by any of the external modules or the keyboard independently of other. The external modules are coupled serially to each other with a peripheral device, such as a keyboard, disposed most remotely from the central unit. The modules are serially connected in an open chain to the central processor for communication bidirectionally by an address signal to the intended respective module and an attention acknowledgment signal back to the central processor indicating a readiness for data reception.
