Hi Matt, that is strange PB1 and PB2 are mixed within reef-pi, something must not be assigned correctly. The bottom DB9 in your pic is PB1 and the equipment screens looks good. At this point I don't think it's hardware related as the DB9's are connected directly to the Pi so for PB1 DB9 not to work would require 8 damaged pins on the Pi which I think is nearly impossible. Could you post images of all the connectors assigned in reef-pi on the connectors screen? Maybe I can spot something there.
