NMEA MESSAGES
The Invicta 115 receiver can be used to communicate with other electronic devices including Raven’s
RGL 500 Swath Guidance Light bar. A communication protocol (set of rules) known as the NMEA 0183
standard has been established by the National Marine Electronics Association. The NMEA 0183
standard contains numerous message formats such as the ones described below which the Invicta
115 receiver uses to communicate with other devices.
