Apparent wind angle 180 degrees off

[Atlantis]

I have Navnet 3D and i believe an FI 5001. When my apparent wind is right on the bow the instrument show it as coming from 180. This error is consistent at all wind angles. Is there a set up configuration step missing? Thanks in advance for any assistance.

What device does the FI5001 directly connect to?

 

[Atlantis]

I think it connects to the NavNet. Is that a specific enough answer? I get the data on the NavNet monitors and the same thing on the RD33 locations of which there are 3.

The FI5001 is an analog device and cannot connect directly into an RD33 or NN3D.
Where does the masthead cable connect? There might be a hidden FI50 or FI70 instrument.
