Light signals from interactions in the argon are detected by a system of 38 photo-multiplier tubes (PMTs), 19 above and 19 below the TPC volume inside the argon cryostat. We describe the electronics which processes the signals from the photo-multipliers, the trigger system which identifies events of interest, and the data-acquisition system which records the data for further analysis. The electronics include resistive voltage dividers on the PMTs, custom pre-amplifiers mounted directly on the PMT voltage dividers in the liquid argon, and custom amplifier/discriminators (at room temperature). After amplification, the PMT signals are digitized in CAEN waveform digitizers, and CAEN logic modules are used to construct the trigger; the data acquisition system for the TPC is based on the Fermilab artdaq software. The system has been in operation since early 2014. %G English %Z DarkSide %2 https://hal.science/hal-01669661/document %2 https://hal.science/hal-01669661/file/agn1.pdf %L hal-01669661 %U https://hal.science/hal-01669661 %~ IN2P3 %~ OBSPM %~ CEA %~ LPNHE %~ APC %~ CNRS %~ PSL %~ SORBONNE-UNIVERSITE %~ SU-INF-2018 %~ SU-SCIENCES %~ UNIV-PARIS %~ UP-SCIENCES %~ OBSPM-PSL %~ SU-TI %~ ANR %~ ALLIANCE-SU %~ TEST3-HALCNRS %~ LPNHE-2
