Interfacing system using an auto-adapting multi-ported control module between an i/o port and a plurality of peripheral adaptors via bus extending cables

摘要

A self-adapting interface assembly on a data processor allows communication with a variety of other data processing devices operating under different communication protocols. The assembly comprises an input and output signal translating module installed between the data processor input/output port and a cable terminated by simple adaptor modules for coupling to various types of data processing devices. The adaptor can sense the type of device and send to the translating module an identifying bit stream. The translating module uses the device identification to programmatically change the configuration of data receivers and drivers and control signal buffers in order to assure exchange of data between the data processor and the device connected to the adaptor module regardless of their respective electrical interface characteristics.
