Abstract:
1. A method of differentiating nodes in a multi-node electronic system, comprising: establishing an intended configuration for the system, the configuration including a number of nodes to be installed and a specification of intended node location, the intended configuration being determined before the nodes are installed by a system controller; establishing a node ID for each of nodes to be installed in the system; installing the nodes, by either making or not making electrical connections between circuitry on the nodes and circuitry on a chassis to establish a unique binary identification value for each of the nodes installed, circuitry on each node to report a unique binary identification value for that node to the controller, the unique binary identification values are formed by varying the locations at which a first and second chassis contact are installed and varying the number of first and second chassis contacts installed, and using the node ID established for each of the nodes, determining whether the nodes as installed comply with the intended configuration, in which the controller determines whether each node has reported an expected identifier.
