Hub Némésis

The Némésis Center (HUB) is a central unit that simplifies the installation of the Némésis display system. It centralizes power supply and network connection (Ethernet) to connect up to three Némésis displays via a single main cable, reducing the number of cables to run through the mast or cockpit.

You can connect up to three Nemesis displays to a single Nemesis Hub. It has three dedicated output ports for this purpose.

For installations requiring more than three displays, you can interconnect multiple Nemesis hubs in series (daisy-chaining) to expand the system and connect additional screens.

Yes, the hub is designed for the marine environment. It has an IPX6 and IPX7 protection rating, making it waterproof and suitable for installation in exposed areas.

The Némésis Center (HUB) is compatible with 12V and 24V DC electrical systems. Its operating voltage range is from 10 to 31.2 V DC.

The weight of the housing alone is 240 grams (0.44 lbs).

Yes, it is recommended to install an external fuse for circuit protection. The recommended fuse rating is 6 A.

The hub's maximum power consumption is 2 Watts. This does not include the power distributed to the connected Nemesis displays.

The operating temperature range of the hub is -20°C to +60°C (4°F to 140°F).

The LED indicators provide a quick visual diagnostic of the system status:

PWR: Indicates that the hub is powered on. ETH: Indicates the status of the Ethernet network connection. Display 1-3: Indicate the activity of each connected display.

No, this hub is specifically designed and optimized to work with B&G's Nemesis navigation data display system. It is not intended for use with other brands or models of displays.

The hub uses three 8-pin Ethernet connectors for connecting Nemesis displays.

Power and Ethernet connection to the boat is via a single combined 8-pin Ethernet/Power entry port, greatly simplifying wiring.

Yes, a ground connection is required for correct and secure installation. The hub is equipped with a dedicated M4 grounding terminal for this purpose.

The hub itself operates on an Ethernet network to communicate with Nemesis displays. To display data from an NMEA 2000 network, this data must first be available on the boat's Ethernet network, typically via an MFD (multifunction display) or a compatible gateway.

The main advantage is the radical simplification of wiring. Instead of running multiple power and data cables to your displays, you only need one combined cable to the hub, which then distributes power and data to the three displays.

The hub has the following connections:

1x Ethernet/Power input port (8-pin connector) 3x Display output ports (8-pin Ethernet connectors) 1x Ground terminal (M4)

Yes, the hub housing is designed to be mounted on a bulkhead or any other suitable surface on board, using the mounting points provided for this purpose.

The operating temperature is the range in which the device can be safely used (-20°C to +60°C). The storage temperature is the range in which the device can be stored without damage when powered off (-15°C to +55°C).

Yes, this is one of its main functions. The hub receives power from the boat's system and distributes it to connected Nemesis displays via Ethernet cables, eliminating the need for a separate power cable for each display.
