+\scTitle{Read-out concepts for FPGA-based sub-systems within the CBM detector}

+\scBeginText
+The Compressed Baryonic Matter experiment (CBM) to be built at FAIR consists of
+several individual sub-detectors. Some are based on custom ASICs as front-ends, 
+while others employ FPGA based modules. Here, extensive slow control features
+can be implemented to ease the recording of data and to allow for fast 
+detection of any kind of error condition. Being designed with a free-running
+data acquisition, the demands also include a synchronized read-out, i.e. 
+distribution of a common clock signal to all modules. To reduce the complexity
+of wiring, this is to be done using the same optical fibers as the data transport.
+
+During the past years, TrbNet has been designed and is used in various experiments, 
+initially for the HADES experiment at FAIR. This protocol
+can now serve as a platform for the CBM read-out. In several steps, synchronous
+links with deterministic latency, as well as a free-streaming data transport
+can be included. At the same time, modifications to improve bandwidth and provide
+compatibility to the CERN GBTx links used for ASIC based sub-systems are to be
+developed. This contribution shows the planned steps as well as the current
+status of development.
+
+This work has been supported by BMBF (05P12RFFC7), GSI and HIC for FAIR.
