Marine Protocol - NMEA 2000 Integration

It is a plug-and-play communications standard used to link maritime sensors and display devices aboard ships and boats, and it communicates via the CAN interface.

What Is the NMEA 2000 : Overview And Process of Operation

NMEA 2000(R) Networking can help you make sense of everything, from the functioning of your boat to the weather and the conditions of the sea. 

Gain access to a vast amount of data, including bearing, depth, the state of the engine, the fuel level, and electrical information; you name it, and we can display it via our Marine Marine App Development services


Multi-Sensor Support

Display and quickly comprehend practically any NMEA 2000 sensor using images and text that are user-friendly, high-color, and intuitive. Even data for several engines and fuel tanks may be viewed at the same time.


Simple Customization​

You may easily modify the info boxes to fit your needs, whether fishing or navigating. You can concentrate on a single reading, or you can monitor numerous gauges at the same time, to get a more comprehensive picture.​

NMEA 2000 Core Specification

Group 12951

The NMEA 2000 protocol uses Controller Area Network to link devices (CAN).

Group 12952

NMEA 2000 is based on the high-level protocol SAE J1939. However, it specifies its messages.

Group 12953

NMEA 2000 devices and J1939 devices can coexist. It also offers a much greater data rate (250k bits/sec).

Group 12954

Messages are broadcast by default, with no handshaking signal.

Group 12955

It enables devices from various manufacturers to interact with one another inside the same network without interfering.

Group 12956

All of the messages described in the Application layer and Diagnostic layer are supported by our NMEA 2000l stack.

NMEA Value Proposition-iTechnolabs

Value Proposition

NMEA 2000 Network Integration System

NMEA 2000 is used to construct a system of connected electronic devices, generally among marine equipment. Instruments that comply with the NMEA 2000 standard are linked to a central cable known as a backbone and additional similar connectors known as t-connectors and drop lines.

Frequently Asked Questions

The National Marine Electronics Association (NMEA) was created in 1957 to foster collaboration among electronic manufacturers. During its early years, NMEA focused on enhancing communication among manufacturers. NMEA 1803, and its successor NMEA 2000, are plug-and-play communications protocols designed by NMEA that allow various manufacturers’ devices to connect with one another.

GPS receivers, autopilots, wind instruments, depth sounders, navigation instruments, engine instruments, and nautical chart plotters can be connected to the NMEA 2000 network. Because agents in the NMEA 2000 network can talk to each other, systems can use data from another instrument on the network to take action or show information.

For example, the signals from the GPS receiver can be used to make the autopilot correct the course, and the engine RPM and fuel injection rate can be used to figure out how much fuel is left.

Most of the size of the network you build will depend on how big your boat is. You probably only need a receiver and a Chartplotter on a smaller boat. However, you can add more NMEA 2000-compatible devices if you have a larger boat or if you often need remote controllers nearby, like on a swim platform. The limit is 50, which is much more than most boaters will ever need. This is where everything starts, so buying a good one is wise.

Yes, a power supply is necessary for any NMEA 2000 network. The NMEA 2000 backbone is the sole source of power for a significant number of the devices that make up the NMEA 2000 standard; this electricity is then utilized to run the devices. Although this is the case for the vast majority of devices, it is important to note that the NMEA 2000 network powers, not all devices.

Connectors of several types, including T-connectors and drop cables, are utilized in affixing NMEA 2000 compliant devices to the network, consisting of a central “backbone” cable. This configuration decreases the clutter, and appliances may be disconnected one at a time, making troubleshooting much more accessible. Even older NMEA 0183 devices that you want to incorporate into your NMEA 2000 network may be done so with the help of specialized connections. Let us presume that you have investigated all of your choices and have concluded that it is time to start updating your boat console to NMEA 2000. You should invest in NMEA certified devices of a high grade if you want the maximum benefit from your NMEA 2000 network.
