You can test the USB to NMEA cable by doing a “Loopback” test as follows… You will need a Windows PC to and a copy of TeraTerm which is free to download from the link below… https://osdn.net/projects/ttssh2/releases/ Just select the latest EXE installer version and once downloaded, double click on the file to install TeraTerm. You only need the main program, not all of the extra plugins and language extensions, so untick everything else as shown below…. Once Tera Term is installed, we need to confirm what COM port Windows has allocated to your USB to NMEA Cable. It was COM3 on my PC, butRead More →

In most cases, if your computer is connected to the internet, when you plug the USB to NMEA adaptor in to a spare USB socket, the driver should be automatically installed on Windows/MAC OSX/LINUX. Sometimes with Windows PCs, it is necessary to manually install the USB drivers which can be downloaded from here…. https://digitalyachtamerica.com/download/usb-nmea-adaptor-drivers-v2-12-28-for-windows-exe/ This will download a zip file that when you double click will show a single exe file… Extract this EXE file and then right click on it and select “Run as administrator”… Now plug in the USB cable and check in Device Manager that the USB to NMEA adaptor has beenRead More →

If you have the Seatalk to USB converter, then you can plug this straight in to a Windows, LINUX or Mac computer and use a Telnet Terminal type program to send this command. If you have the Seatalk to NMEA0183 converter, you need to use a NMEA 0183 to USB Adapter. On a Mac we use CoolTerm which is freeware by Roger Meier… https://freeware.the-meiers.org/ You need to make sure that CoolTerm is set to send CR+LF as the Enter (EOL) characters, as this is always used in NMEA 0183 systems to indicate the end of the sentence has been reached. Then copy the command: $PDGY,STalk,OnRead More →

One of the lesser known facts about our 4GXtream, is that it has a built-in GPS receiver and is supplied with a passive GPS antenna. This is primarily for position logging or for enabling a geo-fence alarm function. However, this GPS data can also be transmitted out on the NMEA 2000 network. Assuming that the 4GXtream GPS antenna is connected, it is getting a good position fix and the NMEA 2000 cable is connected to a fully powered up and operational NMEA 2000 network, the notes below will configure the 4GXtream to become an NMEA 2000 GPS position source. From a device that is wirelesslyRead More →

If you think that your AIS transponder is not transmitting your position then this procedure might help you. The first step is to check if your AIS transponder is actually transmitting. If you are then sure that your AIS transponder is not transmitting then the next part explains you the factors to check.   1 – Check if your AIS is transmitting or not   With ProAIS2 or iAISTX/AIT5000 Web Interface Using the proAIS2 configuration software or the iAISTX/AIT5000 web interface allows you to see if the GPS position is OK. You can monitor the AIS reception of other vessels. As well as ensure thatRead More →

With the unit fully powered up i.e. connect power and wait >1 minute for it to boot up, using the supplied SIM removal clip or some other blunt pointed object, gently press and hold the small Reset Switch on the front face of the unit, for at least 5 seconds as detailed below for the Factory Reset function…. The reset button has two functions: Reboot the device. If the reset button is pressed for up to 4 seconds, the device will reboot. Start of the reboot will be indicated by the flashing of all 5 signal strength LEDs together with the green connection status LED.Read More →

If you have the Seatalk to USB converter, then you don’t need any extra cables   If you have the Seatalk to NMEA 0183 converter then you will need an NMEA0183/RS422/RS232 to USB adaptor cable, but the procedure is the same.   Please download the Tech Note that explains the procedure. It is the same procedure for our ST-NMEA, iKonvert and GPS160 products, that all have an STM32 micro. Also download the latest V2.08 firmware. This is a ZIP file which you will need to unzip and there is just one BIN file inside. This is the file that you upload to the ST-NMEA converter.Read More →

Yes, our iKonvert uses the popular FTDI serial to USB chip and the LINUX and MAC OSX drivers for this chip are included in the relevant operating system’s kernel. It should appear in the operating system as a serial device named “ttyUSB0” (or similar) when plugged in to a LINUX or MAC machine.Read More →

Our iKonvert can output converted NMEA 0183 sentences or the RAW NMEA 2000 data depending upon which mode it is set to (see user manual for more details). You can either set the mode by changing the four DIP switches inside the iKonvert or you can do this programmatically by sending a serial command to the iKonvert and the unit will stay in this mode even after a power cycle.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 →
