Which bus system do you have on board?
Choose the bus system already installed on board. Not sure? The identification help below will guide you.

Is there a free connector on your bus?
A free port on a T-piece or distributor carries only a protective cap.
A free port is a connector on a T-piece or distributor that carries only a protective cap. If a cable or a terminator is plugged in, the port is taken. If you can't find a free port, choose No.

SeaTalk 1 connects to the Hub through a converter. We can't confirm without checking whether your specific autopilot delivers every value over this path; get in touch if you're unsure.

- An NMEA cable is not included.
Does the Hub fit my boat?
- Power: 8 to 28 V DC over its own cable, not over the bus
- Bus system: NMEA 2000, SeaTalkNG or SimNet directly by cable, SeaTalk 1 through a converter, no bus with the starter kit
- NMEA 0183: only through a translator
- Internet: Your Hub connects to marina or home Wi-Fi, a router or a hotspot. Hub cellular carries only alarms and live status, with the Standard subscription
- Mounting location: below deck in a dry place, not in the engine room and at least 2 m away from radio, compass and radar
Power over the bus is not supported; the Hub needs its own cable for that. NMEA 0183 directly, without a translator, is not supported; we currently only recommend going through the translator.
Frequently asked questions
Can I mix devices from several manufacturers?
Yes, as long as they fit the same bus. NMEA 2000, SeaTalkNG and SimNet work together with the right cables and adapters; NMEA 0183 runs independently of the other systems.
Where do I feed power into the Hub?
The Hub gets its power through its own cable straight from your boat's battery (8 to 28 V DC), not over the bus.
What is a terminator, and do I need one?
A terminator closes off the bus at each end. If your bus is already fully wired, one is usually already in place; the Hub itself needs no extra one.
Do I need a T-piece?
Only if no port is left free on your bus. Then a T-piece or a distributor shares an existing connection.
Why isn't an NMEA cable included?
Every bus and every cable length needs a different cable. So you don't pay for something you might already have, you choose the right one here.
I have SeaTalk 1, does that work too?
Yes, through a converter. We can't confirm without checking whether your specific autopilot delivers every value that way.
