What are the settings for instruments following the NMEA standard?
Instruments following the NMEA standard will generally work with these settings: baud rate – 4800; bits – 8; parity – none; stop bits – 1; flow control – Xon/Xoff or hardware (you may have to try both: consult your instrument’s Manual), reading protocol – continuous flow, data persistence – 2 seconds.
