Abstract
Interface apparatus allows a serial communicating device to communicate with an echoplex communicating device. A first microprocessor coupled to the serial device converts serial data to a parallel format. The parallel formatted data is transferred to a second microprocessor which is coupled to the echoplex device. The second microprocessor converts the parallel data from the first microprocessor into echoplex data for transmission to the echoplex device. When data is to be transferred from the echoplex device to the first device, the second microprocessor converts the echoplex data to a parallel format. The parallel formatted data is transferred to the first microprocessor, for conversion into a serial form and transmission to the serial device. If both the serial and echoplex devices wish to transmit at the same time, priority is awarded to the echoplex device. The interface operates asynchronously on real time basis, and is transparent.
