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 www.nmea.org or e-mailed to you at no charge. All funds are in U.S. dollars.
