Is your device compatible with my boat?
Our devices are designed for NMEA 2000 networks (except NMEA 0183 Multiplexer, NMEA 0183 to NMEA 2000 gateway, NMEA 2000 Wi-Fi Router, NMEA 0183 Wi-Fi Router and NMEA 0183 Wi-Fi Gateway). The standard was released in 2000, but compatible devices became widely available on the market 5 or more years later. For example, the A-Series (presented in 2006) of Raymarine chartplotters has no NMEA 2000 support, the C-Series Classic (2006) has limited support of NMEA 2000 (SeaTalk2 interface), and the C-Series Widescreen (2008) is fully compatible with NMEA 2000 (SeaTalk NG interface).
So, if your chartplotter and digital instruments were manufactured before 2005, they are compatible with our NMEA 0183 and SeaTalk devices only. Chartplotters and digital instruments manufactured between 2006-2008 may be compatible with our NMEA 2000 devices. Most chartplotters manufactured after 2008 are compatible.
Our NMEA 0183 Gateway allows you to connect NMEA 0183 equipment to a NMEA 2000 network and vice versa. It has a bi-directional converter with wide support of message types including AIS and autopilot.
NMEA 0183 Wi-Fi Gateway allows you to see data from an NMEA 0183 marine devices on a PC or smartphone. It is compatible with virtually all marine software.
NMEA 0183 Wi-Fi Router is a smart NMEA 0183 and SeaTalk multiplexer which also allows you to see data from marine devices on a PC or smartphone. It has four NMEA 0183 ports and one SeaTalk port.
NMEA 2000 Wi-Fi Router is equipped with NMEA 2000 and SeaTalk ports, two NMEA 0183 ports, has three TCP/UDP data servers and a built-in web server, where you can easily configure it or update the firmware. It connects all marine and mobile devices easily and supports all popular marine protocols.
Small boats may be equipped with simple small-screen models of chartplotters which may have limited connectivity possibilities. Small boats may not have sensors or other digital equipment except chartplotters, so they may not have an installed network. The answer is maybe.
Installation and connectors
NMEA 0183 connectors of the NMEA 0183 Multiplexer, NMEA 2000 Wi-Fi Router, NMEA 0183 Wi-Fi Router, NMEA 0183 Wi-Fi Gateway YDWN-02 and NMEA 0183 Gateway YDNG-03 can be connected directly to the NMEA 0183 port or SeaTalk port of a chart plotter.
We recommend installing a new network with NMEA 2000 Micro Male connectors.
Simrad SimNet (with yellow backbone connectors) and Raymarine SeaTalk NG (with blue and white connectors) are still popular, but those companies are starting to use NMEA 2000 Micro Male connectors in recent equipment models.
Figure 1. Basic NMEA 2000 network layout
A NMEA 2000 network’s main components are: (1) backbone cable, (2) T-connectors, (3) two terminator resistors, (4) spur or “drop” cables, (5) DC power source.
NMEA 2000 equipment can be connected either directly to a T-connector or with a spur cable.
The main difference between Garmin NMEA 2000, Raymarine SeaTalk NG and Simrad SimNet is the connector type.
Please refer to the manufacturer’s documentation for a comprehensive installation guide:
- SeaTalk NG Reference Manual (81300-1) for Raymarine networks,
- Technical Reference for Garmin NMEA 2000 Products (190-00891-00) for Garmin networks
Those guides cover basic network architecture overview, a list of available cables, terminators and connectors, technical requirements and practical examples for building a NMEA 2000 network.
Figure 2. ActiSense SBN
For a small network, we recommend ActiSense SBN. It has four NMEA 2000 connectors, terminators inside, and 3m power cable. You only need to connect it to 12V battery.
Our devices are supplied with different types of NMEA 2000 connectors. Models with the suffix R at the end of model name are equipped with NMEA 2000 connectors compatible with Raymarine SeaTalk NG. Models with the suffix N are equipped with NMEA 2000 Micro Male connectors.

Figure 3. NMEA 2000 Micro Male connectors on a multi-port T-connector
If you have Raymarine equipment, choose the SeaTalk NG connector (Fig. 2.). In the case of Garmin equipment, choose the NMEA 2000 Micro Male connector (Fig. 3.).
For other network types, choose the device with NMEA 2000 Micro Male connector, because all manufacturers have an adaptor cables from NMEA 2000 Micro to their proprietary connectors.
For example, to connect our device to a Simrad SimNet network (Fig. 4.) you can use an adaptor cable (SimNet Female — NMEA 2000 Micro Female, i.e. Navico part number 24006199).

It is also possible to connect our device with NMEA 2000 Micro Male connector to Raymarine SeaTalk NG network using an adaptor cable (Raymarine part numbers A06045 or A06075).
All our devices are compatible with NMEA 2000 networks.
To check if your equipment is NMEA 2000-compatible, check the installation manual (and/or user manual) supplied with your equipment. First, make sure that it contains some mention of NMEA 2000 (or a branded version of NMEA 2000: SeaTalk NG, Furuno CAN, or Simrad SimNet).
To check if our device data can be interpreted by a particular piece of equipment, refer to the documentation for your equipment:
- check the supported PGN list in your equipment documentation, then compare it with our device’s supported PGN list given in the appendix of the corresponding user manual,
- if your equipment documentation lacks a PGN list, check which data types are available for display and/or processing. For example, some legacy models of chartplotters lack the ability to show humidity data.
If in doubt, please refer to our technical support and specify exact model(s) of your equipment.
According to the specification, an NMEA 2000 network has two terminators (120-Ohm resistors) connected to the NMEA 2000 backbone endpoints. Device models with the T index at the end of their names contain a built-in terminator and should be connected to the network instead of the terminator. This allows zero-cost connection of the Devices to existing networks that have no free connectors. Sometimes it is hard to find the end of the bus and terminator on large vessels.
