NavAlarm – NMEA 2000 Sounder

All you need is to connect the NavLink2 to your NMEA 2000 backbone. It will take its power automatically from your NMEA 2000 network.

Our WLN10/WLN30 & NavLink2 have a built-in web interface and create a password protected WiFi network. With your tablet, PC or smartphone, if you scan for wireless networks, you should see a wireless network called “DY-WiFi-xxxx” where xxxx is a four-digit code unique to the product. The WiFi network might change according to your product version.

Make your device join this network and you will be asked to enter a password which is “PASS-xxxx” where xxxx is the same four-digit code as in your network name. You can change both the network name and password in the unit’s web interface

All configuration can be done through a simple web interface, just connect to the product’s Wi-Fi network then open your web browser, enter the product’s IP address (192.168.1.1) and you can set baud rates, multiplexing mode, network name, password and join an existing network.

We keep up to date reviews on our news blog at www.digitalyacht.net – search for Best Marine Apps for Android or iOS. Popular apps include Navionics, iNavX, TZ iBoat , iAIS, NavLink, iSailor, SeaPilot, Weather 4D, MaxSea TimeZero, SailGrib and literally 100s more.

Our products are also compatible with navigation software on PC/Mac/Linux.

We keep on our blog a list which explains how to configure all the popular navigation apps & software. This list explains how to configure a NMEA connection (UDP/TCP) on the app/software but also how to configure the AIS settings.

To see the list, please click here: https://digitalyacht.net/configure-apps-software/

Up to 7 devices can connect using UDP. TCP/IP is a one to one connection format. PCs, MACs, Android, Linux and iPhone/iPad are all compatible.

No internet connection is required. Many consumers get confused and automatically associate wifi with internet. The product creates a wifi network and the local iPad or tablet users searches for this in the same way they search for a wifi hotspot.

Once connected, NMEA data is sent over the local link created on board the boat.

Yes! You can program this through the web interface so you just have one Wi-Fi network on board with our product linked directly to your other Wi-Fi network as a client.

This works well as well with Furuno WiFi radar installations.

The Wi-Fi will typically footprint a boat up to 25m LOA. Contact us if you need a bigger footprint or have a steel or carbon vessel.

Our iKonvert/NAVLink2 gateways make implementing NMEA 2000 much easier, with no old, proprietary libraries, just a simple serial protocol that is published online at…

The gateways take care of all of the complicated address claiming, network discovery and NMEA 2000 network management, simplifying and speeding up your software implementation. Here is a link to our iKonvert Developers Guide on GitHub…

You will need a copy of the NMEA 2000 Appendix B in order to decode the NMEA 2000 PGN data, which is available from the NMEA organization.

If you have not already developed software to read and write NMEA 2000 data, then you might want to look at the open source CANBoat software, which supports our iKonvert as detailed in the CANBoat Wiki, see link below. The developer Kees, has over a number of years, reverse engineered the NMEA PGNs and the data is translated in to a more simple and open JSON format.
