The PRESPEC experiment for high-resolution gamma-ray spectroscopy using radioactive ion beams at the FRagment Separator of GSI together with the LYCCA-1 calorimeter and the AGATA [1] detector array has been commissioned early 2012. Main goals of the commissioning were to test the new trigger logic using FPGA-based modules and to test the coupling of the two data acquisition systems, NARVAL for the AGATA detectors, and MBS for the FRS+LYCCA detectors. The performance of the DAQ coupling will be presented and various trigger configurations for background suppression will be discussed.
