All NMEA 0183 sentences start with $XX which is called the “Talker ID” and identifies what type of product the data is coming from such as WI = Wind Instrument, II = Integrated Instruments, SD = Depth Sounder, EC = Electronic Charting system, etc.Read More →

Unfortunately it isn’t as simple as just downloading the app on the new Mac and transferring the data over. If you backup/transfer your old mac to a new one, sometimes the problem is that the charts are still locked to the old computer. To transfer the data across, you will need to use the Mac OSX Terminal window. You need to use a ‘command line’ command to clear out the corrupted charts directory on your new Mac. 1) Exit NavLink Uk on your Mac 2) Open Terminal on your Mac and enter: rm -rf /Users/yourusername/Library/Containers/com.pocketmariner.seanav.gb.mac.dy/Data/Library/Application Support/NavLink UK/chartSets/gb/* Replacing yourusername with the user name you useRead More →

If you have an old or spare NMEA 2000 cable kicking around in your “come in handy” box, then put it to good use and create your own NMEA 2000 Test Lead. Assuming your cable is a Male to Female cable, you can actually create two test leads from the same cable, by simply cutting it in half, stripping back the outer insulation and fitting the five wires inside (Red/White/Blue/Black/Shield) to a piece of terminal “chocolate” block – as shown below. The Male Test Lead will actually be the most useful, as the majority of “back bone” connections are female, so you will be ableRead More →

The flashing Red Error LED indicates that your NAVLink2 has quite an early version of firmware. As you can imagine, there are loads of different NMEA 2000 devices installed on boats, of varying age and firmware versions and since we released NAVLink2, we have come across quite a few “odd situations” where unexpected combinations of data have caused our “software watchdog” to detect an issue and restart the NAVLink2. In each of these cases, we have had to release a firmware update for the NAVLink2, to fix the issue. We can update your unit to the very latest version (V2.70) for you free of charge,Read More →

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…   https://github.com/digitalyacht/iKonvert/wiki/4.-Serial-Protocol   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…   https://github.com/digitalyacht/iKonvert   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 writeRead More →

The WLN10, WLN30 & NavLink2 have a built-in web interface. We have released a new web interface as well as some new functionalities. You can now filter the NMEA data and untick specific NMEA sentences which may create conflicts with some apps or software. You can also choose a specific mode for the product, for instance, you can choose the AIS mode to only send AIS and GPS data to get a better result with an app that can only accept AIS & GPS data, such as Navionics. The data monitor has also been improved and it is now easier to save the data. YouRead More →

Since the NavLink2 unit was originally released we have released a few firmware updates to improve performance and add features. The latest version is V2.00 and we would recommend this update to anyone who has an earlier version of firmware on their unit – you can see the version number in the footer of the NavLink2’s main web page. The firmware update file (NavLink2_V2-00_OTA.zip) can be downloaded from our GitHub repository by clicking here. IMPORTANT NOTE – the file you download is a compressed ZIP file, make sure you extract the binary (.bin) file inside and upload this file, not the ZIP file, otherwise you could “brick”Read More →

By default, NMEA to WiFi server’ creates a wireless Access Point (hotspot) on-board your boat. The Name (SSID) of the Access Point will be “NavLink2-xxxx” or “DY-WiFi-xxxx‘, etc, depending on the product you’ve purchased, where xxxx is the unique four digit code of your device. To connect to the NMEA to WiFi server, you will need to scan for wireless networks, find and select it in the network list and then when prompted, enter the default WPA2 password, which is “PASS-xxxx”, where xxxx is the same, unique four digit code that is in the hotspot name. For instance, if you have a WLN30 and theRead More →

If you don’t receive the NMEA data on your iPad or iPhone, then you must follow this procedure: 1- Close all apps in the background or restart your device.  Always a good idea to shut down your iPad/iPhone device and then power it back up again, as this will close all background apps and ensure all of the right services are running. For more information: https://digitalyacht.net/2018/07/27/background-apps-stopping-wireless-nmea-transmission/  2- Local Network Settings If you are using iOS 14 or higher, make sure the “Local Network” privacy settings are enabled for the app they want to use…. Go to Settings>Privacy>Local Network and make sure that the App isRead More →
