I have a project going on and I need help. I have two LRF2-OCR2B occ sensors paired to a two button switch and a Pow Pak. Reading the literature, I don't see an exact sequence of setting these up. There are several ways I can do this: Put the pow pak in setup mode and add the switch and occ sensors at the same time or pair the switch to the pow pak and then pair the sensors to the switch. Which is the correct method?
