For the control of measurements as well as for taking over and pre-processing of the measurement data the NMR-spectrometer BS 487 C/TESLA has been connected on-line with an AMCA 80-microcomputer. This experimental equipment has been integrated in the local computer network ATLAS. For the data transmission and the computer coupling the CAMAC-system has been used. The storage and time intensive programmes for the spectra evaluations are-running in the EG-1040 computer. The data transfer is controlled by the help of a two-party, cooperative communication type protocol. The data acquisition and processing work in dialogue are running under real-time conditions.
