 ====== S800 data format from Event Filter (S800 Filter) ======
 This page describes the data format assembled by the S800 filter. The data is written in a series of 16-bit unsigned integers, subsequently referred to as ''words''. This format is suitable for the output of most of the modules presently used in the S800, and in the case where 32 bit integers are needed, the proper unpacking procedures will be given.
+Note that data from the S800 filter are encapsulated as Ring Items (RI) and, as such, will include a [[http://docs.nscl.msu.edu/daq/newsite/nscldaq-11.2/c185.html|Ring-Item Header]], a [[http://docs.nscl.msu.edu/daq/newsite/nscldaq-11.2/x214.html|Body Header]], and a Body, where the real parsed data are included. Ring Items emitted from the S800 filter are pushed into a [[http://docs.nscl.msu.edu/daq/newsite/nscldaq-11.2/c43.html|Ring-Buffer]] called **s800filter**.
