3.1. NMEA 0183 interfacing

The Wind display has one NMEA 183 input and one output, non-shielded. The NMEA
frame format recognized by the WIND display complies with the V3.01 standard of
January 2002.

3.1.1. NMEA 0183 input interface

The NMEA 183 input interface can simultaneously acquire the 4 physical
measurements listed in the table below. To avoid confusing the same data from
different frames, a 3-level priority management algorithm is used to prioritize some
frames over others.
No NMEA data
1 Boat speed
2 Speed over ground
3 Apparent wind angle
4 Apparent wind speed
Note: The data from the NMEA input are displayed with the

3.1.2. NMEA 0183 output interface

The NMEA output interface of the WIND display emits the following 3 frames at a
rate of 1 Hz:
No NMEA frames
1 VPW
2 MWV
3 VWR
Note: The NMEA output does not repeat the frames received on its input. Although
the VWR frame is obsolete (replaced with the MWV in V3.01), it is emitted to ensure
compatibility with older generation instruments.
