solid state, there is a tool available from china that will work on the newer gcs controllers. have bought and tested a couple. a little over 200 bucks. i only tested it on a Regen controller, but it did give access to all the menus not sure about the new gen2 but i believe all the newer stuff is GCS. maybe some otis guys can weigh in on this
