Maretron NMEA 2000 Network Bus Extender – NBE100-01
Expand and strengthen your onboard digital network with the Maretron NMEA 2000 Network Bus Extender (NBE100-01), a vital component for boaters looking to extend their NMEA 2000 backbone beyond standard length limitations. Designed to improve signal integrity and allow longer cable runs, this rugged extender seamlessly interfaces with your existing NMEA 2000 network to support additional sensors, displays, and devices without sacrificing performance.
Built to Maretron’s exacting marine standards, the NBE100-01 features sealed, waterproof housings and high-quality connectors, ensuring long-lasting reliability even in harsh saltwater environments. By providing a solid link between backbone segments, this bus extender helps eliminate communication dropouts and voltage drop issues, maintaining data flow across your entire vessel network—ideal for larger boats, offshore cruisers, and yachts with distributed instrument clusters or multiple bridge stations.
Whether you’re adding a second helm display, linking remote tank senders, or expanding AIS and GPS connectivity, the Maretron NBE100-01 Network Bus Extender keeps your NMEA 2000 network robust, flexible, and ready for future upgrades.
Key Performance Features
-
Network Segmentation: The NBE100 allows you to segment a single logical NMEA 2000 network into multiple physical segments. This effectively doubles the maximum cable length and allows for more than 50 devices on a single network.
-
Signal Buffering: It acts as a bidirectional signal buffer, ensuring that data messages are passed between segments without degradation, even across long distances.
-
Isolates Faults: Because it creates physical segments, a short circuit or power issue on one side of the extender will often be isolated, preventing the entire ship-wide network from going down.
-
No Configuration Needed: The device is "plug-and-play." It automatically manages the traffic between segments without requiring complex software setup or programming.

What's In The Box
The standard retail package for the NBE100-01 includes:
-
NBE100 Network Bus Extender: The main physical unit featuring two NMEA 2000 Micro connectors (one for each network segment).
-
Mounting Hardware: Stainless steel screws for securing the unit to a bulkhead or under-dash area.
-
Instruction Manual: Detailed technical documentation covering wiring diagrams, segment termination rules, and network design best practices.
Key Installation Requirements
Because the NBE100 physically splits the network to allow for more devices and longer cable runs, your setup will require additional components not included in the box:
-
Separate Power Sources: Each network segment created by the NBE100 must have its own NMEA 2000 Power Cable.
-
Proper Termination: Each new segment must be terminated at both ends with 120-ohm resistors.
When to Use the NBE100
This device is essential for superyachts or commercial vessels where the "backbone" cable exceeds 100 meters, or when adding a new suite of electronics would push the device count past the NMEA 2000 limit of 50 physical addresses.
Pro Tip: Each segment created by the NBE100 requires its own dedicated power source and proper termination (120-ohm resistors) at both ends of the new segment.
