Remote controlled test interface unit
First Claim
1. A universal remotely controlled test interface unit for operating central processing units and peripheral devices of a data processing system from a remote location comprising:
- a communications transceiver for receiving from a remote data processing unit information containing control signals and data signals,input data control means for receiving and processing said information from said communications transceiver,buffer storage means connected to said input data control means for receiving and storing said data signals,format control means connected to said input data control means for receiving and processing said control signals,control register means for receiving and storing the data contents of said buffer storage means,logic gating means connecting said buffer storage means to said control register means for transferring the contents of said buffer storage means to said control register means under the control of said format control means,said control register means being partitioned into a plurality of groups of storage cells by said control signals to define a parallel line interface compatible with the processing unit to be operated from said remote location by said data signals, andsaid control register means further comprising groups of control storage cells and groups of data storage cells adapted to test the unit to be operated from a remote data processing unit.

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.
