The ZEUS central data acquisition system consists of several centralized tasks which supervise the data taking of the experiment and transfer the data to the IBM 9000/720. The control system ensures the sequencing of the various data taking cycles with 17 sub detector components contributing a total of about 250,000 electronic signals. The monitoring system performs monitoring of data taking as well as environmental monitoring with regard to the functioning of the entire detector. Data accepted by the Third Level Trigger is transmitted to archival storage on the IBM 9000/720 via 1.5 km long fiber optic link cable. A fraction of complete event records is also transferred to the VAX cluster for online histogramming and event display.
