This contribution focuses on the deployment and first results of the new data acquisition system (DAQ) of the COMPASS experiment at CERN laboratory. The COMPASS experiment is a fixed target experiment with maximum rate of 1.5 GB/s. The DAQ utilizing FPGA-based event builder is designed to be able to readout data at maximum rate of the experiment. The DAQ is developed under name RCCARS (run control, configuration, and readout system). The RCCARS has been deployed for the pilot run starting from
