NMEA 2000 network bus extension with PGN filtering

The NMEA 2000 network bus extension NBE100-01 is designed to optimize and extend marine communication infrastructures. It functions as a network bridge with integrated PGN filtering capability, enabling targeted management of data traffic on NMEA 2000 networks.

The 'PGN filtering' (Parameter Group Number) is a feature that allows precise control over the information transmitted between different segments of an NMEA 2000 network. Its benefits include:

Reduced overall load on the network bus.Ensuring critical data reaches its destination without unnecessary latency.Improved network performance and reliability.

The NMEA 2000 certification of the NBE100-01 confirms its compliance with stringent safety and interoperability standards. This certification requires passing over 100 tests covering aspects such as:

Message priority management.Automatic device addressing.Product recognition on the network.Resistance to electromagnetic interference (EMI) and noise.Electrical isolation to prevent disruptions.This compliance ensures reliable integration and advanced compatibility within the NMEA 2000 ecosystem.

The NBE100-01 improves network performance in several ways:

By physically extending network range.
By allowing segmentation of network sections for better management.
Thanks to its integrated PGN filtering, which reduces overall bus load by transmitting only relevant data to the appropriate segments.
By ensuring critical data is delivered without excessive latency.

The NBE100-01 is designed for demanding marine environments. It is tested to IEC 60945, ensuring suitability and robustness for use in marine navigation and radio communication systems.

The NBE100-01 is specifically described as a network bridge (Network Bus Extender or Bridge). It extends or segments a NMEA 2000 network, unlike a gateway which converts data between different network types or protocols (e.g., NMEA 2000 to USB or IP).

Electrical isolation is a key feature of the NBE100-01, part of the NMEA 2000 certification tests. It ensures the product does not disrupt the network in the event of an electrical issue, thereby protecting the integrity and stability of the entire onboard NMEA 2000 system.

Yes, the NBE100-01 is designed to help reduce latency. Through its PGN filtering, it ensures critical data reaches its destination without unnecessary delay by reducing the overall bus load and optimizing the flow of information between network segments.

The product is a Maretron NBE100-01 NMEA 2000 network bus extension. It is referenced in Maretron’s technical documentation and is part of their certified NMEA 2000 product range.

The NBE100-01 is designed as a scalable component for optimizing and expanding marine communication infrastructures. It can be used to improve the performance and reliability of NMEA 2000 networks of various sizes, whether extending a small network or segmenting a larger one for better traffic management.

The NBE100-01 is exclusively designed for NMEA 2000 networks. Its NMEA 2000 certification ensures full compatibility and interoperability with all other NMEA 2000-certified products and equipment.

Although the NBE100-01 is NMEA 2000 certified, using non-certified or merely 'compatible' or 'conforming' NMEA 2000 products can cause issues. Unverified and untested products do not guarantee compliance with safety requirements and may disrupt the network. For maximum reliability and safety, only use NMEA 2000 certified products and cables.

To ensure the highest level of reliability, interconnection, and security, it is recommended to use NMEA 2000-approved and certified cables and connectors with the NBE100-01. These components are designed to meet the stringent specifications of the NMEA 2000 protocol.

Yes, the NBE100-01 is part of the Maretron ship monitoring and control ecosystem. It is designed to integrate seamlessly with other Maretron products certified NMEA 2000, thus contributing to the creation of a 'smart boat' with a common interface for all systems.

You should use the NBE100-01 to extend your NMEA 2000 network when:

You need to increase the physical range of your existing network.You want to segment your network to improve performance and reliability.You are experiencing high bus load and wish to reduce it via PGN filtering.

Yes, one of the key functions of the NBE100-01 is to enable segmentation of your NMEA 2000 network. This can improve performance and reliability by isolating sections of the network and precisely controlling the data flowing between them via PGN filtering.

The ideal location to install the NBE100-01 depends on the specific architecture of your NMEA 2000 network and the purpose of the extension or segmentation. It must be strategically placed to effectively divide the network or extend its range, while being in a protected environment compliant with marine standards (IEC 60945) for which it has been tested. It is advisable to plan the location based on the desired network topology.

The NBE100-01 provides quality and reliability assurances through its NMEA 2000 certification, which confirms it has passed over 100 rigorous tests. Additionally, it is tested to IEC 60945 standards, attesting to its robustness and suitability for demanding marine environments. These certifications and tests ensure high performance and durability of the product.
