      I am using my A027 to connect Raymarine ST60 wind instrument to OpenCPN 5.6

      Wind angle is displayed correctly, but windspeed is approx. 2 times the speed on the ST60 display.

      The NMEA debug in OpenCPN shows that windspeed value in knots is correctly sent as 5.1, but the Unit field shows meters/second instead of knots.

      <GREEN>22:13:45 (Serial:COM3) $IIMWV,73.0,R,,N,A*27<0x0D><0x0A>
      <GREEN>22:13:45 (Serial:COM3) $IIMWV,,R,5.1,M,A*14<0x0D><0x0A>

      My A027 unit is a few years old so maybe the firmware needs an update.

      I cannot see the current firmware version in the config tool.
