NMEA 0183 Standard
The
NMEA 0183 Interface Standard defines
electrical signal requirements, data
transmission protocol and time, and specific sentence formats for a 4800-baud
serial data bus. Each bus may have only one talker but many listeners. This standard is intended to support one-way
serial data
transmission from a
single talker to one or more listeners. This data is in printable ASCII form and may include information such as position, speed,
depth, frequency allocation, etc.
Version 4.10 cancels and replaces NMEA 0183 V 4.00, published in November 2008, and constitutes a technical revision. Version 4.10 includes updates to
AIS new sentences due to changes at ITU. Version 4.10 expands the GNS sentences to include Galileo. This version also includes a new
wiring diagram published in collaboration with RTCM and the USCG. There some new sentences as well. It is in theory backward compatible to version NMEA 0183 2.00.
Any updates to Version 4.10 within a one-year period from the date of
purchase can be downloaded at
National Marine Electronics Association - NMEA or e-mailed to you at no charge. All funds are in U.S. dollars.

There is also a high-speed addendum to NMEA 0183 V 4.10, called NMEA 0183-HS (High Speed) Version 1.01. This standard operates at a 38.4K-baud rate. Specific sentence formats are common to both NMEA 0183 and NMEA 0183-HS and are defined in the NMEA 0183. The NMEA 0183-HS sells for $140 for members and $250 for non-members for the electronic version. A paper version is available for $200 for members and $300 for non-members, plus shipping/handling. All funds are in U.S. dollars.
