1. A data communications system in an electrically noisy environment, comprising:
a plurality of communication devices, said communication devices including a host and a number N of clients, N greater than 1, communicated to said host using a first single data conductor daisy-chain loop wherein said first single data conductor daisy-chain loop originates and terminates at said host and wherein said first single data conductor daisy chain-loop comprises said number N+1 of conductor segments, each particular one conductor segment of said first single data conductor daisy-chain loop communicating an upstream communications device to a downstream communications device; wherein said first single data conductor daisy-chain loop is routed through a region of the electrically noisy environment having a time-varying magnetic field capable of generating a noise induced signal having a peak magnitude on an order of a threshold magnitude of data signals transmitted over said first single data conductor daisy-chain loop, said first single data conductor daisy-chain loop communicating said communications devices in a first communications order.
