Testing NMEA0183

NMEA Display Program

Back in the 1980s the National Marine Electronics Association (NMEA) defined an interfacing standard that would revolutionise the way marine electronics operated together. For the first time a common standard was defined that allowed equipment from different manufacturers to talk to each other and do things that had previously been impossible.

After a few iterations (NMEA0180 and NMEA0182) the NMEA0183 standard was published and gradually manufacturers developed products that had NMEA0183 Inputs and Outputs that could be connected together. There were some teething problems but over time NMEA0183 established itself as a very compatible and reliable interface standard and even today most marine electronic systems have at least one NMEA0183 interface, although the newer NMEA2000 standard is gradually taking over.

Online information on NMEA0183 is fairly limited and often quite old, but Actisense publish a useful booklet on NMEA0183 and this website http://www.catb.org/gpsd/NMEA.html has also collected a lot of useful information on NMEA0183.

Testing NMEA0183 systems can be done in a number of ways. The simplest method, just to see if there is data being transmitted or not, is to place an LED across an NMEA0183 output. One way round the LED should flash and the other way round it will not flash. If the LED fails to flash in either direction then no NMEA0183 data is present. For more information on this type of LED test, please download our Tech Note by clicking here.

If after establishing that there is NMEA0183 present, you wish to go a step further and look at the raw data to see what messages are being transmitted then you will need an old laptop and an NMEA to USB adaptor cable like our Part# ZDIGUSBNMEA. This adaptor cable can easily be connected to any NMEA0183 Output (two wires) and then with suitable software running on the PC, the NMEA0183 data can be displayed and interpreted.


A few years ago, when Microsoft stopped including a utility called HyperTerminal in Windows Vista/7/8,  Digital Yacht developed a useful NMEA Display program that is free to download from here.  Our NMEA Display program is perfect for not only viewing the raw NMEA0183 data but also for interpreting and displaying the different fields of data i.e. Wind Speed, Depth or Heading. For more information on using this program and NMEA0183 in general, please refer to an earlier post we wrote, by clicking here.

With these simple tools and techniques, anyone can test and fault find NMEA0183 systems and with so many systems out there, it is a useful “string to your bow” that might just get you out of trouble.

VHF Antenna Options for AIS

Splitter v Antennas

One of the most common questions we are asked by our AIS customers, is “what antenna should I use for my AIS ?”, so we thought we would post a short article to provide an answer.

Basically there are two options; fit a second dedicated VHF antenna a suitable distance from the vessels main VHF antenna or use the main antenna for both VHF and AIS by fitting a special device called a “Splitter”.

Generally our recommendation for yacht owners who want to fit an AIS, is to use a “Zero Loss” splitter like our SPL2000. By utilising the main VHF antenna at the top of the mast, you will definitely get maximum transmit range, plus the ease of installation often makes it a cheaper option than paying for a second antenna to be installed.

However, for power boaters who do not benefit from the height advantage of using the main antenna at the top of the mast and for AIS receiver owners where the splitter can often cost more than the AIS receiver itself, it is often desirable to fit a second VHF antenna, particularly if you intend to save money by doing the antenna installation yourself.

We have already covered the issue of AIS antenna separation in another post, so we will not repeat this information again, but we will just touch on the issue of “AIS Tuned” antennas versus normal VHF antennas.

AIS operates on two dedicated channels within the marine VHF frequency range – 156.0 to 162.025 MHz. The two AIS channels are at the top end of this range namely; 161.975 and 162.025 MHz (channels 87B and 88B). Most VHF antennas are designed to give maximum gain across the whole VHF frequency range centred on Channel 16 (156.8 MHz).

Pretty much all of the antenna manufacturers now produce “AIS Tuned” antennas, which have their centre frequency shifted from Channel 16 to 162Mhz (exactly half way between the two AIS frequencies). If you are going to mount your AIS antenna on the stern rail of a yacht or radar arch of a power boat, then using an “AIS tuned” antenna to get an extra bit of gain to compensate for the antenna being effectively at deck level, is a good idea.

AIS Tuned Antenna Graph

The graph above shows how the tuning of the antenna to 162MHz gives it an extra boost in VSWR (gain) across the two AIS frequencies.

Which ever option you choose, having AIS on your boat will without doubt make your sailing experiences safer and less stressful in poor visibility or when crossing busy shipping lanes. Even a simple receiver with a small whip antenna at deck level will keep you informed of what ships are around you and which ones you need to keep an eye on.

London’s Little Ship Club host Next Generation Navigation Presentation from Digital Yacht

Tuesday 24th February at 1915 will see The Little Ship Club in London host the first of a series of talks from Digital Yacht entitled “Next Generation Navigation”

lsc talk


The compass was invented in the 1400s and the sextant and log came in the 1700’s.  It then took nearly 300 years for electronic navigation to become part of everyday boating and in the last 10 years we’ve seen unprecedented change in marine electronic technology.  So what’s happening today and more importantly for tomorrow so you can keep up to date.  Digital Yacht will explain and explore next generation navigation with a detailed look at positioning system beyond GPS, AIS, the latest interfacing capabilities through NMEA 2000 plus electronic mapping, radar, iPad integration and the connected boat.

Don’t miss it.  Contact Little Ship Club for details





Navionics App + Digital Yacht WLN10 = Amazing Sonar Charts Live

The Navionic’s iOS and Android app has proved incredibly popular with boaters throughout the world and it’s now just introduced some game changing features.

The Miami Boatshow 2015 saw Navionics pick up the Innovation Award for their new Sonar Chart Live platform and the best news is that it’s designed for and compatible with our wireless NMEA devices – like AquaWear, WLN10 and NavLink.

The new version allows NMEA depth and GPS data to be integrated into the app allowing iOS devices (like iPads without the GPS feature) to utilise boat data when connected through a Digital Yacht NMEA-Wireless server.  Even if your iPad has GPS (the 3G/4G models), you’ll benefit from enhanced accuracies from your boat’s systems, better battery life and reception below decks – so your iPad really will be an integrated part of the boat navigation network.

But here’s the real plus….

Navionics can now record depth information from your NMEA connected instruments, depth sounder or fish-finder allowing a real time depth contour to be built onto your chart.   When connected to a WLN10 (details HERE), depth data is streamed to the app and shows an updated depth contour onto the detailed chart.

Watch the depth contours updated on you chart as you cruise.  Installation is easy – just like this via a simple 2 wire NMEA 0183 connection:

WLN10-01Here’s a picture too of what to expect – and when you see in real time, it’s awesome:

Collected data is then also sent to Navionics (when you have an internet connection) to be post-processed who then process and update your chart with a download – not just with your data but with other users too allowing for the best possible crowd sourced information.  As they say, “Want better charts? Go boating!”  Check out the video below
