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.

Version 3.01 (released Jan. 2002), the latest version of the standard, sells for $270, plus shipping/handling via priority mail within the US and global priority mail outside the US. Orders are processed on Tuesdays and Fridays of each week. The document can be shipped via FedEx using YOUR FedEx account number. Any updates to Version 3.01 within a one-year period from the date of purchase will be mailed to you at no charge.

Please note that certain websites offer explanations and examples of NMEA 0183 sentences. In most cases they are very old versions or incorrect interpretations and should not be depended upon for accuracy.

There is also a high-speed addendum, NMEA 0183-HS Version 1.0, to Version 3.01 of NMEA 0183. 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 $110.

You may purchase both the NMEA 0183 and NMEA 0183-HS for $340. You may order online using a Visa, MasterCard or American Express. You may also call our office at 410-975-9425 and give the charge card authorization information. Please make checks payable to NMEA and mail to NMEA, Seven Riggs Avenue, Severna Park, MD 21146. Checks must be in US dollars and drawn on a US bank. Purchase orders are accepted in conjunction with payment.
