I believe the interface for PFC equipment is still a work in progress and may not be fully implemented yet. I would recommend you check the free demo first because the full version of the simulator will function exactly the same way. We expect this hardware to work properly before X-Plane is final, but it might not be there quite yet.
ETA: Get the demo here.
