The main task of the read-out electronics for the new NUMEN focal plane detector (FPD) is the real-time data collection from the front-end ASICs and the high bandwidth transmission to data acquisition, in addition to the slow control of the front-end electronics and the synchronization of the whole detector. The read-out electronics architecture, designed to be modular and expandable to the final size of the detectors, is based on System On Module (SOM). This very versatile device couples high performance FPGA to powerful processor architecture and allows a graphical approach to the programming and interfacing. A detailed description of the architecture and the specifications of the read-out electronics are presented.
