1. A method for determining the physical locations of a plurality of devices coupled to a series connected network, each of said devices having an unique identifier on said network, comprising the steps:

  • (a) performing the following steps (b)-(e) for each of said devices;

    (b) severing a device from said network such that the series connection is blocked;

    (c) sending queries to each of said devices for requesting said devices to provide identification responses, said queries being injected at a predefined node along said network;

    (d) associating the identifier of said severed device with said responses from said queried devices;

    (e) reattaching said severed device to said network; and

    (f) after completing steps (a)-(e), determining physical locations of said devices based on said responses and said associated identifier of the severed device, said responses being indicative of said physical locations of said queried devices relative to said severed devices.
