Connection of the TRA-1001 computer to output systems of a measuring centre

The authors describe a device for data file output from a TRA-1001 computer through an outlet switchboard of a measuring centre (MC) onto a digitizer, graph plotter and BESM-4 computer. A channel for programmed data transmission is used to operate TRA-1001 with MC outlet units. The computer functions in the expectation mode, i.e. consecutive input-output and transition instructions are periodically transmitted. A logical circuit for communication control and an output flow chart are presented. The communication control block is based on TRA-1001 computer elements and comprises three circuit cards positioned in the vacant zones of the amin TRA-1001 post. The device has been used for over two years to show reliable and convenient output of accumulating measurement data
