I have a customary H5000 setup on my boat with my nav PC connected to the Actisense NGT as well as hard wired ethernet to the GoFree router.  All is working well with one exception:  my wind angle data are correctly displayed on my B&G displays but are jumping back and forth between correct and incorrect data in Expedition.  Since other data depends on wind angle, such as sail selection, those data are flickering as well, which is of course quite annoying.  Analyzing the data on the N2K bus, it appears that I have three sources of wind data.  One source with the correct angle, two other sources with incorrect angles.  The B&G displays ignore the erroneous data but Expedition takes in both correct and incorrect wind angle data.  I guess my question is, can I limit Expedition to selecting only one source of wind angle data from the N2K bus (so that erroneous data gets ignored)?  Or can I turn off the unwanted source of B&G data altogether (so that the erroneous data don't show up in the PGN messages).
