Description:

This NMEA 0183-HS (High Speed) Version 1.01 standard defines electrical signal requirements, data transmission protocol, and timing for a 38.4K-baud serial data bus.  Each bus shall have only a single TALKER but may have multiple LISTENERs.  Specific sentence formats are common to both NMEA 0183 and NMEA 0183-HS and are defined in NMEA 0183.  Standard rate NMEA 0183 operates at 4800-baud and utilizes a different electrical interface.  This standard is intended to support one-way serial data transmission from a single TALKER to one or more LISTENERs.  This is data in printable ASCII form and may include information such as position, speed, depth, frequency allocation, etc.  Typical messages might be 11 to a maximum of 79 characters in length and generally require transmission no more often than once per 20 milli-seconds.

The electrical definitions in this standard are intended to operate at 38.4K-baud, a higher data rate than 4800-baud NMEA 0183.

Because of differences in baud rate and other transmission parameters, NMEA 0183 interfaces are not directly compatible with earlier NMEA 0180 or NMEA 0182 Standards.

NMEA 0183 Sentence Formatters are defined in NMEA 0183.
