The AugerPrime upgrade of the Pierre Auger Observatory
converts the existing surface detector, consisting of an array of
1660 water-Cherenkov detectors (WCDs), into a multi-hybrid
instrument. This upgrade required improved surface detector
electronics and acquisition software to accommodate the new
detection channels corresponding to the scintillator surface
detectors, radio detector antennas, and the underground muon
detectors as well as the additional, small area photomultiplier in
the WCDs. In this work, we present an overview of the data
acquisition software, both at the level of individual detector
stations and the central data acquisition system. We highlight the
modifications performed to handle the new multi-hybrid data of
AugerPrime and cope with surface detector stations with different
hardware configurations operating simultaneously in the array during
the transition phase.
