How are Garmin GPS receivers used in NMEA 0183?

In addition to the standard NMEA 0183 sentences, Garmin GPS receivers may transmit or receive information over their serial interface using NMEA 0183 compliant Garmin proprietary sentences. These proprietary sentences begin with the characters, “$PGRM”, instead of the characters “$G” that are typical of the standard NMEA 0183 sentences.

How is data transmitted in the NMEA 0183 standard?

Although the standard calls for isolated inputs and outputs, there are various series of hardware that do not adhere to this requirement.

What’s the difference between NMEA 0183 and RS422?

While NMEA0183 only defines an RS422 transport, there also exists a de facto standard in which the sentences from NMEA0183 are placed in UDP datagrams (one sentence per packet) and sent over an IP network. The NMEA standard is proprietary and sells for at least US$2000 (except for members of the NMEA) as of September 2020.
