Abstract
A universal remotely controlled test interface test unit is adapted to be connected through plug connections to an on-site computing system having one or more central processing units and associated peripheral equipment. The test interface unit is provided with a limited function keyboard control for initiating tests and a transceiver for communicating with a data processing unit at a remote location which supplies format and control signals for use by the test interface unit and data signals to be communicated to the on-site computing system. The data signals received by the test interface unit are first entered into a buffer register to provide parallel outputs. The format control signals activate logic gating signals to cause the data signals in the buffer register to be arranged in a control register in a format which is compatible with the equipment to be tested. The control register is arranged to operate any part of the central processing system under test and any of its intended modes of operation and to initiate readout of information from any part of the computing system through the transceiver for processing and examination by the remotely located data processing unit.
