ABSTRACT:
A method and apparatus for testing for correct connection together of circuit elements in a circuit formed of a plurality of redundant circuit portions. A coded signal is generated at a first circuit element and transmitted upon a signal path believed to connect the first circuit element with a second circuit element. If the coded signal is detected at the second circuit element, the correct connection of the first circuit element together with the second circuit element is verified. Because a coded signal is generated, the correct connection between the circuit elements can be verified even when the signal path connecting the first and second circuit elements is formed of an optical, or other non-electrical, coupler.
