CSV files are constructed using either the time drive or the type drive strategy. Time drive gives one line per time interval and may include values of several data types. Type drive gives one line per count type and time interval and may include a type description.
Hence patterns associated with the two different strategies are conflicting and may not be used in conjunction. The patterns %i and %o are used with time drive and patterns %c, %d, %r and %v are used with type drive.
%i : in
%o : out
%c : type-code
%d : type description
%r : short type description
%n : counter name
%s : camera serial number
%v : value
%t : timestamp
%u : Unix timestamp
%S : separator character
