Abstract

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.

Serial Shifting Interface (S 2 I)

Idee: Carlos E. Medina, US–Concord

A Serial Shifting Interface (S2I) is intended to beused in cases where one side (the control side) is in aprotected  EMI  (electromagnetic  interference)  safeenvironment, whereas the  other  side  (the  moduleunder  control)  could  be  into high electrical noisyenvironments (e.g. high voltage modules, high cur-rent switching, under ionized radiation) where CPUs(central processing units)  could  be  affected  in  anegative manner.

The physical layer of a point to point communicationprotocol requires one single CPU running the soft-ware in the control side, and discrete logic withoutCPU, in the  module  under  control,  to  receive  andtransmit digital information by three fiber optics. Thesingle CPU will be responsible for sending data tothe module and for interpreting the data sent by themodule.

The new system is less complex in comparison tostate of the art systems and it has a predefined resetcondition, so that this recoverable feature of S2I willpermit the two modules to be completely independ-ent, and the communication could be established atany moment.
