Specifically, delay time = signature code x unit delay duration; the selection of the feature codes is related to that at most n displays possibly exist in the same POE power supply domain, and the sum of currents of the n displays needs to be ensured to be smaller than the protection current of the POE power supply domain.
The selection of the feature code is related to the longest possible delay starting time of a certain display under the same POE power supply domain. Since the longest delay time affects the user experience to some extent, the feature code needs to be selected such that the longest delay time is expected to be small if a is satisfied.
