Detailed description

The Digital Yacht AIS-AIT5000 transponder is a cutting-edge AIS Class B+ system based on SOTDMA technology. With a transmit power of 5W, it offers increased detection range and faster update rates than traditional Class B transponders limited to 2W (such as the AIT2000). This power ensures better visibility and priority allocation of transmission slots, a critical safety advantage in high-traffic navigation zones.

Integrated zero-loss VHF splitter

The AIT5000’s major innovation is its certified "zero-loss" VHF antenna splitter. This internal component allows the ship’s main VHF antenna to be used simultaneously for VHF voice communications and for AIS data transmission/reception. This design eliminates the need to install a second dedicated VHF antenna, reducing wiring complexity, windage, and installation costs without any degradation in signal attenuation.

Multiplexing and global network connectivity

Designed as the heart of the onboard data network, the AIT5000 provides comprehensive connectivity. It includes an NMEA 2000 port (N2Net) for direct connection to modern multifunction displays (Garmin, B&G, Raymarine). It also features two NMEA 0183 inputs and two outputs, configurable at 38400 and 4800 baud. The device acts as a multiplexer: it merges incoming NMEA 0183 instrument data with its own AIS and GPS frames, redistributing them via its high-speed NMEA 0183 output, USB port, and Wi-Fi interface. The bidirectional Wi-Fi module (TCP/UDP, IP address 192.168.1.1) enables telemetry broadcasting to tablets or smartphones, while providing an integrated web interface for initial configuration (MMSI entry), making PC software optional. The unit is compatible with 12V and 24V DC electrical systems.

Expert opinion

Pol CONIN

« The ultimate 5W SOTDMA solution with multiplexing and integrated splitter »

Integrating the AIT5000 from Digital Yacht represents a highly strategic technical solution for electronic retrofitting of vessels. Upgrading to the 5W SOTDMA standard is a modern safety imperative, ensuring priority transmission amid the growing saturation of AIS frequencies by 2W classics. The decisive technical advantage of this model is its integrated "zero-loss" VHF splitter, which allows retaining the existing VHF antenna at the masthead, optimizing AIS range without the constraints of a new coaxial cable installation. This transponder excels particularly in its multiplexing capabilities, consolidating NMEA 0183 streams (often from legacy instruments) to simultaneously push them onto the NMEA 2000 backbone and via Wi-Fi, ensuring a smooth transition to display on tablets.

Frequently Asked Questions

Need help? Contact us

What is the difference between this Class B+ 5W transponder and a standard Class B transponder?

The AIT5000 uses SOTDMA technology with a 5W transmission power, compared to 2W for a standard Class B. This provides increased detection range, faster position updates, and priority allocation of transmission slots in high-traffic areas.

Is an additional VHF antenna required for the AIT5000?

No. The AIT5000 includes a certified zero-loss VHF antenna splitter. It lets you use your boat’s main VHF antenna simultaneously for VHF radio and AIS data transmission/reception without any signal degradation.

Is the GPS antenna provided with the transponder?

Yes, the AIS transponder AIT5000 is supplied with its own GPS antenna, essential for accurately transmitting the vessel's position, speed and heading to other boats.

How to configure the AIT5000 with my boat's information?

Configuration is done easily via the built-in web interface. You can use a PC, Mac, tablet, or smartphone connected to the device's Wi-Fi, then open a web browser to enter your MMSI number and your boat's dimensions.

What supply voltage is required to operate this transponder?

The AIT5000 is designed to operate on 12V or 24V DC shipboard electrical systems (accepted range: 9.6V to 31.2V). It is recommended to protect the installation with a 3A fuse or an appropriate circuit breaker.

How to connect the device's power supply?

Power is connected via the supplied main cable. The red wire is the positive pole (+) and the black wire is the negative pole (-).

Is the transponder compatible with my NMEA 2000 chartplotter?

Yes, the AIT5000 features an integrated NMEA 2000 (N2Net) interface, enabling direct and straightforward connection to modern multifunction displays from brands such as Garmin, B&G, or Raymarine.

Can old NMEA 0183 instruments' data be retrieved?

Yes. The device acts as a multiplexer: it has two NMEA 0183 inputs. It merges data from your existing instruments with its own AIS and GPS data, then redistributes them via its NMEA 0183, USB, and Wi-Fi outputs.

How to connect the AIT5000 via Wi-Fi to my navigation tablet?

The AIT5000 creates its own Wi-Fi network. Simply connect to it with your tablet, then configure your navigation app to receive data via the IP address 192.168.1.1 on port 2000 (TCP or UDP protocol).

What are the dimensions of the AIT5000 housing?

The transponder housing is very compact. Its dimensions are approximately 220 mm in length, 130 mm in width, and 55 mm in height, making it easy to install behind a bulkhead or chart table.

What is silent mode and how to activate it?

Silent mode allows you to disable the transmission of your AIS data while still receiving transmissions from other vessels. It can be activated via the web interface or by installing a physical switch connected to the blue and white wires of the data cable.

What does the flashing yellow light at startup mean?

A flashing yellow light indicates the device is powered on but waiting to acquire a valid GPS position before transmitting its first AIS report. This typically takes 3 to 4 minutes after power-up.

How to provide GPS data to my DSC VHF radio from this transponder?

You can use the low-speed NMEA 0183 output (4800 baud) of the AIT5000, specifically designed for this purpose. Connect the pink wire (TX+) and the purple wire (TX-) to the NMEA input of your VHF radio.

What to do if the device's red LED starts flashing?

A flashing red LED indicates an issue with the VHF antenna or the antenna splitter (VSWR error). We recommend checking your VHF antenna and cables, and using the web configuration interface to read the precise error message.

Can I use the AIT5000 with a laptop for navigation?

Yes, the AIT5000 features a bidirectional USB connection that creates a virtual COM port at 38400 baud on your PC or Mac, allowing navigation software to receive all multiplexed AIS, GPS, and NMEA data.

Is it possible to check the status of the VHF antenna via the device?

Yes, the AIT5000 web interface allows you to monitor transmission and reception statistics, including the VSWR value (Voltage Standing Wave Ratio), which provides an indication of the quality and condition of your VHF antenna installation.

What do the yellow and blue LEDs lit simultaneously indicate?

This LED combination indicates that silent mode is currently enabled. Your AIS transponder is receiving nearby AIS targets but not broadcasting your vessel's position.

Does the MMSI number need to match the one in my VHF radio?

Yes, the MMSI number programmed in your AIS transponder must be strictly identical to the one assigned to your vessel and programmed in your VHF radio. This number is issued by the competent maritime authorities.

How to connect a chartplotter to high-speed NMEA 0183?

To send AIS and GPS data to a chartplotter on NMEA 0183 at 38400 baud, use port 1 of the AIT5000. Connect the orange wire (TX+) and the brown wire (TX-) to the corresponding input on your chartplotter.

Can I modify the MMSI number myself if I make a mistake?

For safety and regulatory reasons, once the MMSI number is registered in the transponder during the initial setup, it cannot be modified by the user. In case of an error or a change of boat, the device must be reset by a professional.
