3.1 – Connecting to NMEA 2000 Network • Connect the NavLink2 cable, to a spare connector on the NMEA2000 network. • NavLink2 takes its power (LEN=2) from the NMEA2000 network so no additional connections are necessary. • If you are creating a new NMEA2000 network, then you may wish to consider Digital Yacht’s NMEA2000 Starter Kit, that provides all of the cables, connectors...

TCP is the default protocol that NavLink2 uses, and is best for fast, secure, single device connections. TCP mode must be used for driving an autopilot. • If you wish to allow multiple devices (up to 7) to receive the NavLink2 data at the same time, you should select UDP protocol. •...

Figure 2 • The following table shows the various NMEA2000 to NMEA0183 conversions the NavLink2 supports. MODE Interface NMEA DATA Sentences 0 - Gateway NMEA0183 GPS/Navigation/Instruments RMC, HDG, VHW, MWV, DPT, MTW,MDA, APB, RMB, VLW, XTE, ROT, RSA 1 - Gateway HS (Default )
• To see what data the NavLink2 is converting and sending to your app, from the Home page, go to the “View Data” page as shown in Figure 3. Figure 3 • If your app does not support particular sentences or it is receiving the same data from another device, you can filter certain sentences by clicking the “NMEA Data Filter”...

+ STA” mode, where the NavLink2 will always create its own network, even when Station mode is selected and NavLink2 has joined another network. This has the advantage that you can always access the NavLink2, even if you have made a mistake with the Station mode configuration i.e. mis-typed the wireless password.

It’s “Status” LED will initially flash but then stay ON if it has successfully joined the network. If you make a mistake with a setting or forget a password, reset the NavLink2 to factory defaults by pressing and holding the Reset button for 10 secs or more.
NOTE – Most operating systems will show a “No Internet” warning when connecting to a wireless device like NavLink2. This does not indicate a problem, it is just warning you that NavLink2 does not have a connection to the internet like a normal wireless router would normally have.

Port 2000 By default the NavLink2 is set to operate in TCP mode but you can select UDP mode using the web interface. Most apps that support UDP connections do not ask you to enter the IP address just the port number, however if they do, set an IP address of 0.0.0.0...
