 \maketitle
+The on-going development of the support electronics of the CBM Micro-Vertex-Detector (MVD) was 
+focused on two major aspects: First, the integration in a new DAQ system (based on the TRB3 system 
+developed by HADES) and, second, the design of an integrated control and monitoring interface for 
+systems consisting of several sensors.
 
+\section{New Electronics}
+The major goal of front-end electronics development was to migrate the read-out to a new, more 
+powerful read-out platform, TRB3. Even though the central parts of software and FPGA designs need 
+not to be changed, the read-out chain between digital electronics and sensors was redesigned to 
+gain better performance and additional monitoring features. Here, also the principal structure of 
+the chain was simplified by dropping the separated connection for control signals and merging all 
+supply and data lines for a sensor on one common cable.
 
+Special care was taken for the most sensitive supply voltage, a biasing voltage for the pixel 
+matrices of the sensors. Here, several generation and distribution schemes are foreseen to 
+investigate which setup results in the best noise performance. Furthermore, all relevant voltages 
+and currents can be monitored remotely to further study the behavior of sensors and, subsequently, 
+to design a matching powering scheme for the final detector setup.
+
+In the current connection scheme, the new FPGA platform can support up to 16 sensors in parallel. 
+Note that this value is mostly limited by the number I/O connections for the huge number of control 
+and monitoring signals in the current design version and is likely to increase in future 
+iterations. The resources of the FPGA also allow for further data sparsification algorithms like 
+cluster detection as described in~\cite{cluster}.
