1. Introduction
This document provides a detailed description of the communications protocol for the
following Airmar products:
• DST200 Depth/Speed/Temperature TRIDUCER® multisensor
• DT200 Depth/Temperature sensor
• DT200S Depth/Temperature sensor with optional external Speed sensor
• D200 Depth sensor
• D200ST Depth sensor with optional external Speed/Temperature sensor
• ST200 Speed/Temperature sensor
These products are all expected to be certified to the NMEA 2000® 1 standard.
In this document, the term DST (as distinct from the individual product names DST200,
DT200, DT200S, D200, D200ST, and ST200) refers generically to all of the products
embodied herein.
For further information about the NMEA 2000® protocol, refer to the document, NMEA
2000® Standard for Serial-Data Networking of Marine Electronic Devices, version
1.200. This document is available from the National Marine Electronics Association
( www.nmea.org ).
2. NMEA 2000® Interface
Each of these products has a single NMEA 2000®-compliant network interface, and is
expected to be certified as a Class 1 Level B device. The sensor transmits and receives
standard and proprietary NMEA 2000® Parameter Groups via this interface. Transmitted
PGNs (Parameter Group Numbers) are described in section 2.3. Received PGNs are
described in section 2.4.
2.1. Terminology
The following terms related to the NMEA 2000® protocol appear on the detailed PGN
pages to follow.
PGN: Parameter Group Number. NMEA 2000® messages are organized into logical
collections of data called Parameter Groups. The NMEA assigns each Parameter Group a
unique Parameter Group Number, or PGN.
