| Jan 18, 2021 at 23:32 | comment | added | Justme | Do you have the DMX standard and MAX485 datasheet open to do comparison? The reason you see both is that RS485 chip manufacturers use two different conventions. Some name the inverting output A and some name the non-invertìng output A. DMX standard defines signal true (+) high being logic 1. | |
