Abstract :
The HERA-B experiment is dedicated to the measurement of CP-violation in decays of neutral B-mesons. The B-mesons are produced in a formidable background of inelastic proton-nucleon interactions. The challenge for the DAQ system is a dead-timeless readout which requires unprecedent speed of storing and processing the data. The data acquisition system has been installed in summer 1999 and it was providing data for detector and trigger commissioning runs in summer 2000
