The Projectile Spectator Detector (PSD), a sampling lead/scintillator forward hadron calorimeter with transverse and longitudinal segmentation and with MPPCs photodetectors, will be used at the Compressed Baryonic Matter (CBM) experiment at FAIR to measure the centrality and orientation of the reaction plane in nucleus-nucleus collisions. After amplification in the FEE, signals from the MPPCs are readout with LMT9011 ADCs with 14 bit digitization and up to 125 Msps rate which has been developed for the ECAL of the PANDA experiment at FAIR. The Kintex 7 FPGA is used for signal processing and data collection. The trigger-less readout is based on the GBT-FPGA. Clock source switching from onboard generator to the RX clock transmitted via GBT has been implemented to integrate the ADC board into the CBM DAQ system. One PSD module has been integrated into the mCBM experiment at the SIS18 facility of GSI/FAIR joining the FAIR Phase-0 program. Details of the PSD readout electronics and first results of the data processing and transmission within the common, synchronized mCBM data transport taken during the data campaign in November/December 2019 will be presented.
