A multiplexer is a NMEA0183 data hub (legacy computers), since multiple devices that “speak” in that “language” cannot be directly connected. Instead, a Gateway translates between different “languages” (Seatalk, NMEA0183, NMEA2000, SignalK, …). The latter may, in turn, be provided with a multiplexer section for NMEA0183

In general, all equipment prior to 2003-2005 communicates through Nmea0183, except the Raymarine’s old ones that communicate through Seatalk. The new equipment works with Nmea2000. Our Gateway converters cover all cases. Consult the specifications of your equipment to know if they use Nmea2000 or not.

The Ocenav converter creates a wireless data network based on the same WiFi system that is used on the ground. The difference is that from this network it is only possible to access the ship’s data, since the network of networks is not always accessible on the other side: the internet. Furthermore, the gateway can also be configured as a client of another WiFi access point that may be connected to the internet.

You can use the plotter to mark a waypoint or route and navigate to it. The specific pilot control commands (AUTO, STBY, WIND VANE, TRACK, +1, -1, etc) are only operative from our remote control (ATM105B). The gateway translates these generic remote control commands for the pilot that is installed, be it Raymarine STxxx, Evolution and Simrad B&G on Simnet. That is, it does not “translate” between them.

There are many possible cases depending on the installed radar model. Old radars generally don’t allow it. Only some send a type of data (ARPA / MARPA) that describes the targets identified by the radar. These will be presented on the screen of some apps (OpenCPN, for example), in a similar way to AIS targets.
In the case of using a new model of radar antenna, there are several options: 1- Connect the Ocenav gateway as a client of the radar manufacturer’s network so that everything is available on the same network. 2- Use a radar plugin in OpenCPN and a remote desktop. In this way, the radar screen can be duplicated on another PC or tablet. Neither of these solutions is easy to configure.

The question is relatively simple, and is answered by answering a few simple questions:
a) Do I have an NMEA2000, SeatalkNG or Simnet network on my ship, or do I think I may have to install it someday? If so, the appropriate choices are ATM105A1N and ATM105A3.
b) Do I want to have the Ocenav remote control ?. If so, the models that communicate with the remote control are ATM105A2 and ATM105A3.
In summary: All the gateway models are compatible with older Raymarine equipment (Seatalk). And they all have WiFi. The ATM105A1N cannot operate with the remote control. The ATM105A2 does not have NMEA2000.

It is necessary to install the Ocenav gateway so that the radio signals from the remote control pass to the autopilot network cable. In other words, the gateway acts as a remote control receiver. You will have to opt for the ATM105A2 (For older Raymarine STxxxx pilots) or ATM105A3 (For all types of pilots, except older B&G and Simrad pilots).

Yes, although it is cheaper to purchase a pack (ATM105C2 or ATM105C3)

The remote control works with all old Raymarine and new Evolution pilots without the need for the Seatalk-SeatalkNG converter. It is also operational for Simrad and B&G pilots AP24, AP44, NAC2, NAC3, that is, those that connect to the SimNet network. It does not work with Furuno or Garmin pilots.
