3.1. NMEA 0183 interfacing
The Multi S400 display has one NMEA 0183 input and one output, non shielded. The NMEA
0183 frame format recognized by the Multi display complies with the V3.01 standard of January
2002.
3.1.1. NMEA 0183 input interface
The NMEA 0183 input interface can simultaneously acquire the 5 physical measurements listed
in the table below. To avoid confusing the same data from different frames, a 3-levl priority
management algorithm is used to prioritize some frames over others. Example: if the frames
VTG and RMC are received, only the VTG frame will be decoded to receive the SOG data.
