The Compressed Baryonic Matter Experiment (CBM) is one of the core experiments of the future FAIR facility at Darmstadt/Germany. The fixed-target experiment will explore the phase diagram of strongly interacting matter in the regime of highest net baryon densities with numerous probes, among them open charm. Open charm reconstruction requires a vacuum compatible Micro Vertex Detector (MVD) with unprecedented properties. Its sensor technology has to feature a spatial resolution of <5μm, a non-ionizing radiation tolerance of >1013 neq/cm², an ionizing radiation tolerance of 3 Mrad and a readout time of few 10 μs/frame. Thinned Monolithic Active Pixels Sensors, developed at IPHC Strasbourg, are promising candidates, if integrated in an ultra-thin detector, employing high-performance materials such as thermal CVD-Diamond. The need of prototyping and characterizing the CBM-MVD motivated the construction of a ultra-low mass, high precision detector setup incorporating several prototype stations. Each station contains 2 (single-sided station) or 4 (double-sided station) identical 50 m thick CMOS sensors. The sensors are glued to CVD diamond carriers which provide at the same time a mechanical support and an efficient heat evacuation. This contribution will focus on mechanical integration and operation of the telescope as well as the concept of the customized DAQ system.
