Abstract
System(s) and method(s) are provide to efficiently assess performance of a set of light emitting diode (LED) strings in an illumination system. A multiplexer component collects input signal from the one or more LED strings via a first set of one or more monitoring pins, processes the collected input signal, and extracts at least one output signal. The at least one output signal is conveyed to a demultiplexer component through a second set of one or more monitoring pins, wherein the number of elements in the second set of monitoring pins is equal to or smaller than the number of monitoring pins in the first set. The collected input signal is processed in accordance with at least one mode of operation of the multiplexer component, the mode of operation autonomously configured by the demultiplexer component. The multiplexer component can autonomously generate intelligence on operating status of the set of LED strings.
