26. Conclusions DAQ successfully used to commission all current ND280 detectors with multiple sub-detectors commissioned and calibrated simultaneously Also deployed as QA DAQ systems for module production DAQ ready to accept INGRID diagonal modules and ECAL P0D & barrel modules summer-autumn 2010 Now in daily use for beam data taking Data rates to tape are within acceptable limits CPU load on FPNs low (~5% RXT, ~10% DPT)
