/*
        SSD has 10 ladders, 16 modules, 2 sides, 768 strips each 8bits wide

        However! The DAQ maps the data as:
                40 pseudo-rows
                        64 pseudo-pads
                                192 pseudo-timebins (strips)
        
        The pseudo-rows are constructed as
                ReceiverBoard[0..3] * 10 + Mezzanine[0..1] * 5 + ASIC[0..5]
