\subsection{IPU Data Format}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+Each word sent by an OEP can be of three types as shown in table \ref{MDCDataFormat}:
+\begin{itemize}
+ \item The standard, compressed data format with two hits in one data word
+ \item The long, debug format, with one word per hit.
+ \item Status words which can be of several types, see table \ref{MDCDataFormatStatusWords}
+\end{itemize}

+\subsubsection{FanPW}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+One voltage regulator block on the FanPW is shown in figure \ref{fanpw}. The position of each of the five potentiometers is shown.
+
+The suggested voltage settings are:
+\begin{itemize}
+ \item 6V: Set to 5.85V, resp. 6.2V due to heavy noise on power cable
+ \item 3.8V: Set to 3.8V, resp. 4.1V
+ \item 1.8V: Set to 1.8V, resp. 2.1V
+ \item +3V: Set to approx. 3.1V (should be 3.0V $\pm$ 0.05V on the OEP)
+ \item -3V: Set to approx. -3.1V (should be -3.0V $\pm$ 0.05V on the OEP)
