View all the data supplied by on-board instruments
This multiplexer box aggregates the information provided by onboard instruments (GPS, magnetic compass, depth sounder, wind vane-anemometer, loch-speedo), or the AIS (cartography of surrounding vessels) and sends it via WiFi to onboard devices (PC, tablet, smartphone, etc.).
On an iPad or Android tablet, for example, data can be displayed in the following compatible navigation applications: Weather4D Routing & Navigation, Sailgrib, iNavX, iSailor and others.
The Miniplex-3Wi-N2K is multi-standard: it supports NMEA0183, NMEA2000, Seatalk1 and SeatalkNG data, converting from one standard to another if necessary.
Multiple connection options
The Miniplex-3Wi-N2K is bi-directional, meaning it gathers and sends information from instruments to receivers (tablet, PC, plotter), but it can also receive commands, for example to take control of the autopilot via Wi-Fi (see below)
It incorporates :
- 4 configurableNMEA 0183 input ports from 4800 to 57600 baud, of which N°1 can be configured as SeaTalk1
- 1NMEA2000 input/output port (Micro-C screw connector) for direct connection to NMEA2000 networks (Garmin type), or via an adapter cable for certain proprietary protocols (SeatalkNG, Simnet, etc.).
- 1 WiFi input/output
- 1 USB input/output (for PC connection)
- 2 NMEA Out (for connection to autopilot, plotter, VHF DSC, etc.)
All incoming signals are filtered and converted if necessary, and retransmitted on all outputs.

Driver support:
The Miniplex-3Wi-N2K features an Override mode that can be activated to take control of the driver via the router, and therefore via a tablet or PC.
For example, with a tablet equipped with a compatible navigation application (Weather4D, iNavX, Sailgrib WR...):
- When the tablet is switched on and a route is active on the application, information from the other instruments is directed exclusively to the tablet, and not to Out1. In this way, it is the tablet that feeds the data seen by the pilot ( override mode).
- When the tablet is switched off, the system automatically switches back to normal mode after 10s, i.e. wind and magnetic heading data are supplied directly to the pilot via Out1.
Note: in all cases, manual pilot control remains available!
Simple installation
The NMEA0183 inputs/outputs are easily wired using push-buttons, and are galvanically isolated to prevent short-circuits.
For connection to a NMEA2000 network, simply connect via the Micro-C format connector on the side (note: an adapter cable is required for Seatalk NG or Simnet, which use a different type of connector).
Features
- 1 NMEA2000 input/output port (standard male Micro-C connector)
- 4 NMEA 0183 input ports (one of which can be set as SeaTalk)
- Outputs: wifi + USB + two NMEA Out ports
- 12V DC power supply (range: 8-35V)
- Consumption: 100mA (150 mA max)
- Dimensions: 138 x 62 x 30 mm
Note for NMEA2000 connection:
- With a SeaTalkNG network: a Raymarine converter cable ref. A06045 or A06075 is required.
- With a SimNet network: a Navico converter cable ref. 24006199 is required.
