Hi Nathan,
Also the "Sun Shield" (which works rather poorly on the FO stations) looks slightly different. The "real" FO station (WH-3081) on that Holman webpage is this one. Did you buy a complete station or just a "spare part"?
Before (if) you return that Vane, please can you check the wire/colour connections at both ends of the cable. If it's Fine Offset compatible , I would expect the sequence of the pads on the PCB to NOT be the same as in the RJ11 plug, i.e. I think the WIND and GND should be on the two middle contacts with VCC and DATA on the two outer contacts of the plug.
That vane PCB is very interesting because several people have proposed (personal) projects to "improve" the FO Vane by replacing the Reed switches with Hall Effect sensors, and here it appears already to have been done comercially. It is well-known that the 8 "intermediate minor" directions (ENE, etc, when two reeds are supposed to close at the same time) occur much less frequently (i.e. for less than 22.5 degrees) than the "primary" directions. Personally, I'm working on two "projects" (unfortunately progressing very slowly) to improve this aspect of the FO Vane. One is a pure hardware addition, the other primarily a "software" solution.
It's a pity that I'm on the other side of the world because I have several FO Vanes (they only cost £10 , AU$20 as a spare part here) and would love to get my hands on yours to Reverse Engineer it.
Cheers, Alan.
