Looking for a Class B AIS transponder?

Its always good to have a few weeks at boat shows and listen to customer questions.  Differences between models always crop up as Digital Yacht have a big selection of Class B AIS transponders on offer.  We hope this document helps you decide which is best for your installation.  All units share a common technology platform so will give excellent performance and importantly have future proof SatTrak technology built in.

AIT1500 Series

All AIS transponders require their own dedicate internal GPS (you can’t use a NMEA feed from an existing GPS).  The AIT1500 series has a super sensitive internal antenna which cuts down on the need for another external antenna.  It will work well even below decks on GRP vessels but steel or wood will attenuate the signal too much.  The AIT1500 series is therefore great for RIBs, Center Consoles and GRP sail boats.  With many larger sail boats now fitting multi function displays in the cockpit, it can be unobtrusively installed in a location adjacent to the MFD and the same for flybridge motor boats.

The AIT1500 comes in two versions – one for NMEA 0183 based systems and one for NMEA 2000 systems.  The later is also self powered from the NMEA 2000 bus so installation really is plug ‘n play.  Both models have a USB interface for PC & MAC for programming and PC plotting.

AIT2000

Has dual NMEA 0183 and NMEA 2000 interfaces plus USB and ships with a dedicated external GPS antenna.  Its a great solution for wooden and steel vessels that require an external GPS antenna

AIT3000

Appropriately called “Nucleus” as it forms a hub in any marine electronics system.  It features our patented ZeroLoss VHF antenna splitter technology so the main VHF antenna can be shared with VHF and AIS which means no need for another VHF antenna and sophisticated connectivity including not just NMEA 0183 and NMEA 2000 but also WiFi for iPad and tablet interfacing.  Up to 7 wifi connected devices can be attached and neat NMEA interfacing allows instrument, AIS and GPS data to be used by hundreds of compatible apps.  There’s also a FM radio antenna outlet.

Here’s a 5 minute guide on Youtube and of course we’re standing by on email and phone to answer any queries.  Digital Yacht – for your biggest and best choice in Class B AIS.

AIT2000 + GX2000E a Great Combination

AIT2000+GX2000E

Our AIT2000 Class B AIS Transponder is most commonly installed with an AIS compatible Chart Plotter, so that the AIS targets can be displayed on the electronic chart. However, on sail boats it is often desirable to turn off the chart plotter on longer legs to reduce power consumption, but then you no longer have an AIS display.

The Standard Horizon GX2000E VHF is unique in that it has the capability to display AIS targets and also features closest point of approach (CPA and TCPA) alarms which constantly monitor for dangerous AIS targets and warn you when you are on a potential collision course with them.

The combination of our AIT2000 and the Standard Horizon GX2000E, makes for a very powerful AIS display system that consumes significantly less power (typically < 1A) than a colour chart plotter. Add to this the fact that you can quickly make a DSC call from the GX2000E to any of the targets in its AIS List and you find that this combination matches or out performs many integrated systems, costing much more.

For anyone who wants an AIS transponder and a fully integrated VHF radio that can display and make DSC calls to other AIS targets the AIT2000 and GX2000E are a perfect combination. When compared to a normal VHF only radio, you are effectively getting a full function AIS display, with CPA alarms and DSC calling for just £50 more, which represents excellent value for money.

Interfacing is pretty straight forward and Digital Yacht have created a Tech Note showing how the two systems are connected together – please click here to download it. For more information on the GX2000E visit http://www.standardhorizon.co.uk/product_info.php?cPath=178_173&products_id=100020

5 New Products to be Launched at Southampton

SBS2013 Five New Products

A busy summer of development, sees five new Digital Yacht products having their first public viewing at the Southampton Boat Show 2013 this month.

Headlining is the GPS150 DualNav GPS/GLONASS Sensor, along with the new WL450 Long Range “All-in-one” Wi-Fi adaptor, while the new PilotLINK wireless NMEA server for Class A Transponders will appeal to larger vessels that want to get their AIS data on to iPads or Android Tablets. Also making their debut are the new S1000 AIS SART and the GV30 “Combo” GPS+AIS antenna which provides a neat and simple single antenna solution for any Class B AIS Transponder.

If you are visiting the show this year, please come by and see these new products and the rest of our exciting 2013 product range on our UK distributor, CA Clase’s stand (G091) in Ocean Hall.

Wiring details for Wireless Class B Transponder

AIT2000 NMEA Connections to WLN10HS

A customer asked us for a wiring diagram to show how one of our AIT2000 Class B Transponders connects to our WLN10HS to create a wireless AIS transponder solution. We were happy to oblige and thought that it would be good to publish this diagram online, as this AIT2000+WLN10HS combo is proving very popular this season.

It is a simple two wire connection between the AIT2000 and WLN10HS and the wire colours are shown in the diagram. I have not shown the power connections, but the Red(+) and Black(-) wires on both the AIT2000 and WLN10HS need to be taken to the boat’s 12v or 24v supply – we recommend on the same circuit/breaker/switch.

The diagram also shows how the second NMEA output on the AIT2000 can be taken to a DSC VHF radio to provide a GPS position to the radio and how additional NMEA0183 data, such as from an Instrument System, can be connected to the AIT2000. This data is then combined (multiplexed) with the AIS+GPS data so that a single wireless stream of data is sent to the iPad/iPhone.

In order for the data to be received and displayed correctly on the iPad/iPhone, you will need a suitable app such as iNavX, iSailor or iRegatta, but as you can see from the diagram it is a very simple installation and one of the reasons why going wireless is attracting so much attention.

More information on using our AIT2000 transponder with OpenCPN on Mac and LINUX PCs

Following on from our previous post on using our AIS products with the popular open source navigation software OpenCPN,  Digital Yacht have released a new Tech Note that explains how to get our latest AIT2000 Class B Transponder working with OpenCPN on a Mac or LINUX PC. Under Windows, there is not a problem, but on a Mac or LINUX machine, the AIT2000 is not shown in the list of available COM ports but by entering the device name manually, you can easily get GPS and AIS data in to OpenCPN. Our Tech Note tells you how click here to download a copy.

NEW – Pilot Plug 10m Extension Cable for AIS Class A Transponders

After receiving  a request from our UK distributor CA Clase, we have created a new 10m Pilot Plug Extension Cable which will be a very useful accessory for any large vessel fitted with an AIS  Class A transponder.

As their name suggests, Pilot Plugs were defined by the IMO as a simple and easy way for Pilots coming on board a vessel to connect their laptop to the vessels AIS transponder to get GPS and AIS data whilst onboard.

Most Pilot plugs are about 1-2m in length and have a USB plug on one end and the special 9 way Amphenol connector on the other end which connects to the AIS. On some vessels it is useful to be able to extend this cable length, but as standard USB cables are limited to 5m it is better to extend the RS422 section of the cable. This is where the new 10m Pilot Plug Extension cable from Digital Yacht comes in and allows any Pilot Plug (not just the popular Digital Yacht model see image below) to be safely extended.
