The new High Acceptance DiElectron Spectrometer HADES has been setup at GSI Darmstadt and is now ready to take data. The ATM-based data aquisition together with a multilevel trigger system will be able to read out 70 000 channels with a first level trigger rate of 105 Hz with zero supression and transport 1−2 × 103 events to mass storage every second. To operate this complex system consists of more than 1 000 frontend and over 100 VME boards with a large number of different tasks and layouts, a run control system based on the EPICS package has been developed making use of its network communication layer, monitoring capabilities and sequencing. In particular an interface has been developed that allows to bring several thousand parameters from different sources to the run control system and to write back status information to a database. The layout of the system will be presented.
