NMEA 2000 Networks

NMEA 2000 Networks and SeaTalkNG (STng)

NMEA 2000 is the established standard for communication between marine electronic devices such as navigation instruments, engine control, sensors, and autopilots. An NMEA 2000 network makes it possible to connect multiple systems in a robust and efficient network with plug-and-play installation.

SeaTalkNG (STng) is Raymarine's variant of NMEA 2000 and is fully compatible with the standard, but uses its own cables and connectors. STng networks are common on boats with Raymarine equipment and require specific components for correct installation.

In this category, you will find everything you need to build and maintain both NMEA 2000 and STng networks:

• NMEA 2000 Cabling (backbone and drop cables)
• Connectors and T-pieces
• STng Cabling and STng Connectors
• Distribution Components and Terminators

Difference between NMEA 2000 and STng:

• Standard: Both are based on the same communication protocol.
• Cables and Connectors: NMEA 2000 uses standardized Micro-C connectors, while STng has Raymarine's own design.
• Compatibility: STng can be connected to NMEA 2000 via adapters.

Advantages of NMEA 2000 and STng:

• Standardized communication between different Manufacturer
• Easy installation with plug-and-play components
• Robust and reliable data transfer for all marine systems
