/*
  A major problem is the numbering of the
  RO componenets: do they all start from 0?
  I think yes but mapping and coding (THIS class)
  must be arranged accordingly.

  So far TDC channels and ID are bound to start from 0
  whereas ROB, ROS and DDU are free to start from 0 
  or from 1. This has to be coded into the map
