Selling a Airmar PB200 nmea2000 weather station, I bought this off eBay as working did not install for a year now I find the options board is missing.

Working without the options board is

Air Angle, Air Speed, Barometer and Air Temperature as tested.

A chart plotter will need to use it's own GPS data or a GPS puk to calculate apparent wind speed and apparent direction as the missing options board includes a GPS.

Can also be used in a weather station build when combined with a nmea2000 wind display.
