The Sloan Digital Sky Survey (SDSS) will image n steradians about the north galactic cap in five filters, and acquire one million spectra using a dedicated 2.5 meter telescope at the Apache Point Observatory in New Mexico. We describe the data acquisition system for the survey's three main detectors: an imaging camera, mounting 54 Tektronix charge-coupled devices (CCD); a pair of spectrographs, each mounting a pair of CCDs; and a smaller monitor telescope camera. We describe the system's hardware and software architecture, and relate it to the survey's special requirements for high reliability and need to understand its instrumentation in order to produce a consistent survey over a five year period.
