All the information is available on all ST60 units (Heading is coming from flux compas). They are all connected via SeaTalk. I am using the NMEA out from my ST60 Graphic. According to the manual it should make data (like Heading) available on the NMEA out.

When using the MiniPlex config tool in my Macbook some NMEA sentences seam to be missing. I realize that:
- the problem is probably not related to MacENC

Could it be:
- A problem in the Raymarine unit?
- Something not right configures in the MiniPlex?

I would verify that ALL your ST60 instruments are indeed interconnected and that the data you are missing is actually appearing at the unit from which you are taking your feed to the mux. Some Raymarine installations use 2 Seatalk busses, 1 for wind, depth, etc. and 1 for fluxgate, AP and course computer. There should be a Seatalk output available at the Raymarine course computer, if you take that output to the mux, does the missing data appear (and the data you currently have disappear)? Make sure you have NO filters enabled in the mux when you do this test.
