I have a building that is primarily bacnet mstp. We have added a new Viessmann Vitocrossal 200 with Vitotronic 300 Lontalk interface. I am trying to get the Viessmann to communicate to our Trane Tracer SC controller. It is the only Lon device in the building. The lon communication wire goes directly from the Tracer SC controller to the Viessmann Lon card. The odd thing is that the Viessmann Lon card has 2 ethernet style connections rather than a screw terminal connection. I am not sure how to connect my Lon wire to the Viessmann controller. We have tried a few different things and I can't seem to communicate with the Viessmann.
