Detailed description

Hub Némésis tvrtke B&G centralni je mrežni prekidač namijenjen za centralizaciju napajanja i podataka vaših navigacijskih pokazivača. Omogućuje povezivanje do tri višefunkcionalna ekrana Némésis veličine 9 ili 12 inča putem jednog glavnog kabela, čime se smanjuje zapetljanost kablova na brodu, bilo da je riječ o postavljanju na jarbol, u kokpitu ili na kormilarskom mjestu.

Položaj huba Némésis u ekosustavu B&G

Za razliku od tradicionalnih instalacija koje zahtijevaju zasebno izvlačenje kabela za svaki ekran, kao što je slučaj s B&G Triton² ili H5000 serijama, ovaj koncentrator djeluje kao mrežni prekidač specifično dizajniran za seriju Némésis. U usporedbi s konkurentskim rješenjima poput Garmin GMS 10 koji se ograničava samo na prijenos podataka, hub Némésis istovremeno distribuira mrežne podatke (Ethernet) i električnu energiju prema povezanim ekranima. Tako omogućuje sinkronizaciju navigacijskih podataka, grafičkih mjerača i kontekstualnih moda (uz vjetar, po vjetru, niz vjetar) na više ekrana uz minimalnu latenciju.

Električne karakteristike i povezanost

Ovaj uređaj integriran je u električne sustave od 12 V i 24 V DC, s prihvatljivim radnim naponskim rasponom od 10 do 31,2 V DC. Vlastita potrošnja iznosi 2 W, na koju se dodaje snaga distribuirana ekranima (maksimalno 60 W). Jedinica uključuje zaštitu protiv obrnute polarizacije, preniskog i prenapona, osiguranu preporučenom osiguračem od 6 A. Sučelje sadrži 8-pinski konektor za glavno napajanje i Ethernet, tri 8-pinska Ethernet konektora za ekrane te M4 uzemljivačku priključnicu. LED indikatori prikazuju stanje napajanja (PWR) i prijenos podataka (ETH i priključci 1 do 3).

Otpornost na okoliš i instalacija

Dizajniran za izložena morska okruženja, hub posjeduje zaštitne stupnjeve IPX6 i IPX7, osiguravajući vodonepropusnost prema prskanju morskih valova i privremenom uranjanju. Funkcionira u temperaturnom rasponu od -20 °C do +60 °C (skladištenje je dopušteno od -15 °C do +55 °C). Sam uređaj težak je 240 g, a ukupna težina pakiranja iznosi 1,2 kg. Uređaj se isporučuje s kompletom za pričvršćivanje, interkonekcijskim kabelom za ekran dužine 0,6 metara koji olakšava "plug-and-play" instalaciju, te zaštitnim čepovima za neiskorištene priključke.

« Simplification and robustness for your Némésis displays »

The Nemesis hub is the cornerstone of a clean and reliable B&G display installation. Its centralized design solves the classic problem of running multiple cables through the mast or console by consolidating power and Ethernet data into a single stream. The ability to daisy-chain multiple hubs provides valuable scalability for large sailboats or multi-station cockpits. Its IPX6/IPX7 waterproof rating and robust connectors ensure flawless performance, even in the most exposed installations. The status LEDs are a simple but crucial detail for quick on-site diagnostics.

Frequently Asked Questions

Need help? Contact us

What is the B&G Nemesis Hub used for?

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

How many Nemesis displays can I connect to a single hub?

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

How do I install more than three Nemesis displays?

For installations requiring more than three displays, you can daisy-chain multiple Nemesis hubs in series to extend the system and connect additional screens.

Is the Nemesis hub waterproof and can it be installed outdoors?

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

What is the required supply voltage for this hub?

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

What is the weight of the Némésis Hub?

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

Do I need to install a fuse to protect the Nemesis hub?

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

What is the power consumption of the hub?

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

What operating temperatures are supported by the Nemesis hub?

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

What are the LED indicators on the hub used for?

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

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

Is this hub compatible with any other displays besides B&G Nemesis?

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

What type of connectors are used to plug in the displays?

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

How does the hub connect to the boat's power supply and network?

The connection to the boat's power supply and Ethernet network is made via a single combined 8-pin Ethernet/Power input port, which greatly simplifies wiring.

Is grounding required during installation?

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

Is the Nemesis hub compatible with a NMEA 2000 network?

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

What are the advantages of using this hub compared to direct wiring?

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

What are the different connection ports on the hub?

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)

Can the hub be mounted on a bulkhead or flat surface?

Yes, the hub’s casing is designed to be mounted on a bulkhead or any other suitable surface onboard, using the designated mounting points.

What is the difference between operating and storage temperature?

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

Does the hub provide power directly to Némésis displays?

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