A Serial Shifting Interface (S2I) is intended to be used in cases where one side (the control side) is in a protected EMI (electromagnetic interference) safe environment, whereas the other side (the module under control) could be into high electrical noisy environments (e.g. high voltage modules, high cur- rent switching, under ionized radiation) where CPUs (central processing units) could be affected in a negative manner. The physical layer of a point to point communication protocol requires one single CPU running the soft- ware in the control side, and discrete logic without CPU, in the module under control, to receive and transmit digital information by three fiber optics. The single CPU will be responsible for sending data to the module and for interpreting the data sent by the module.
