             abstract = "The Schenberg gravitational wave (GW) detector has been under 
                         development for the past few years. A scientific run is planned 
                         for the near future. The main technique used to confirm a GW is 
                         the search for time coincident events between multiple detectors. 
                         Therefore, a reliable timestamp is essential for events found in 
                         data from each detector. In the particular case of the Schenberg 
                         detector, we are planning a low latency analysis, which requires 
                         that no data sample be lost during either data acquisition (DAQ) 
                         or transmission, and that time correction be done online. The aim 
                         is to provide reliable data where each sample carries its own 
                         timestamp information. GW event candidates are pointed out after a 
                         dedicated analysis and their time of occurrence are determined by 
                         these samples. We present here the DAQ solution developed for the 
                         Schenberg detector. It is easy to implement this solution using 
                         equipment commonly found in most laboratories. No specific 
                         equipment using precision time protocol or other protocol was 
                         needed to synchronize the sampling. In addition, no transmission 
                         time is needed to be explicitly known. The timing precision is 
                         limited only by the chosen sampling frequency, which fulfills the 
                         data analysis needs.",
