Abstract:
1. A data receiver for use with a data-transmission system having a first channel and a second channel for transmitting nominally-identical data, the receiver comprising: inputs for receiving separately a first message including a first address label and first data from the first channel and a second message including a second address label and second data from the second channel; an inverting mechanism for logically inverting the second message received from the second channel; first and second data-handling devices for receiving separately the first message from the first channel and the inverted second message from the second channel, respectively, and outputting separately the first message to a first message store for storing at a first address coincident with the first address label and the inverted second message to a second message store for storing at an inverted second address coincident with the second address label as inverted; and a processor configured to retrieve the inverted second message from the second message store, to re-invert the inverted second data to retrieve the first message from the first message store at the first address and to compare the first data and the re-inverted inverted second data to identify a common mode failure.
