Abstract:
A method of automatically selecting a mode of operation during initialization of a first multi-mode signal controller for which a desiered mode of continued operation is based on a position of said first signal controller along a communication path that includes a second multi-mode signal controller, said method comprising steps of:enabling signal reception at said first signal controller while disabling at least a portion of signal driving capability from said first signal controller;monitoring said signal reception to detect one of a first signal and a second signal, where said first signal is specific to a communication with said second signal controller and where said second signal is specific to a known pattern of system control;configuring said first signal controller to operate only within a first mode of operation if said first signal is detected; andconfiguring said first signal controller to operate only within a second mode of operation if said second signal is detected.
