 \subsection{Data Unpacker}
 \label{Data_Unpacking}
 The data stream contains SubEvent-IDs and SubSubEvent-IDs to identify the sender of each block of data. While SubSubEvent-IDs are equal to the network address of the corresponding board by design, the SubEvent-IDs can be choosen freely, but are defined to be equal to the network address of the board sending the SubEvent via Gigabit Ethernet. The first digit of each SubSubEvent-ID is sufficient to determine how the following data  has to be handled:
