B&G Nemesis Power/Ethernet Display Hub, For Nemesis 9/12 Sailing Displays, 12/24V, Connects Up to 3 Displays

Overview

The B&G 000-15683-001 is a power and Ethernet hub that lets you link up to three Nemesis 9 or 12 sailing displays at one location on the boat. It runs on 12/24 V DC systems with a 10 to 31.2 V operating range, and it is rated IPX6 and IPX7 for exposed installations where spray and washdowns are part of normal life onboard.

Use it when you want multiple Nemesis displays close together, such as at the mast for race data, in the cockpit for the crew, or at the helm for navigation. One hub location keeps the wiring tidy while still getting Ethernet data to each screen.

Key features

• Connects up to three B&G Nemesis sailing displays through dedicated display ports.
• 12/24 V DC supply with 10 to 31.2 V operating range for typical boat electrical systems.
• IPX6 and IPX7 waterproof rating for installations exposed to spray and washdown.
• 1x 8-pin Ethernet/power connection plus 3x 8-pin Ethernet connectors for the displays.
• Recommended 6 A fuse or breaker on the positive supply feed.
• Status LEDs for power, Ethernet activity, and each connected display.
• M4 grounding point to bond the unit to vessel ground when required by your installation.

Installation and wiring

Mount the hub where the displays are in close proximity, then run your combined feed to the hub and keep the individual display leads short and organized. Protect the positive supply with a fuse or breaker sized to 6 A. The unit powers up when supply voltage is applied.

For the power feed, red is +12/24 V DC and black is DC negative. The yellow conductor is not used and should be insulated. The cable shield can usually be left insulated, but it can be bonded to vessel ground if you are chasing interference from other onboard electronics.

Compatibility and network integration

This hub is intended for use with B&G Nemesis 9 and 12 sailing displays. Connect the Ethernet side into the vessel Ethernet network used by your B&G system so data can be shared across the connected screens. Once wired, the Ethernet link works without special setup.

What’s included

• Nemesis hub (Ethernet switch)
• Fastening set
• Display connection cable
• Blanking caps

Use cases on board

This hub is a good match for boats that want two or three Nemesis displays clustered at the mast, cockpit, or helm, and want a cleaner way to handle Ethernet data and power routing in that area. It also suits race boats where quick at-a-glance data at multiple stations matters, as well as cruising boats that want repeatable visibility of the same key information from different positions.
