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.
