\begin{itemize*}
\item C is the FPGA number. 0 for the central FPGA, 1-4 for the peripheral FPGAs.
\item A denotes the function of the FPGA:\\C: CTS, 8: Hub, 0--1: TDC, D--E other purposes
-\item BB is a number identifying the TRB in the full system. BB is equal on
-all 5 FPGA of one board.
+\item BB is a number identifying the TRB in the full system. BB is equal on all 5 FPGA of one board.
\end{itemize*}
The FPGA with the CTS has address C000 (in already existing systems also 8000). For data unpacking schemes see also \ref{Data_Unpacking}.
