The ClassB unit easyTRX2S receives AIS ClassA and ClassB signals and transmits its own data according to ClassB standard.


All the easyTRX2S series have a great variety of applications: You can connect it to a PC or laptop through a USB port. Using a software, you can choose the speed transmission between 38400 or 4800 Baud data rate. Function activity is shown by 8 LED’s.  The easyTRX2S is able to interpret incoming AIS data for CPA alert or AIS S.A.R.T. emergency messages. Additionally, the easyTRX2S devices can be used as power source for external alerting devices. All received and transmitted AIS data can be stored in and internal SD Card recorder. With the build-in multiplexer input, 3 devices with different baud rate can be plugged to the easyTRX2S units. The external cable gives the possibility to choose between “silent mode” or “PAN PAN emergency call”.

The integrated VHF antenna splitter enables to use an existing VHF for AIS and HF radio at the same time. Before the incoming signals are separated, the built-in pre-amplifier increases the signal strength to avoid physical loss.

The integrated NMEA2000 Adapter enables to connect this AIS transceiver into the latest NMEA2000 network standard aboard.

NMEA2000 is a new data form which enables to plug different devices in a row on the data stream. Each units takes his special data out of the stream. This is also called “BUS-system”.

Up to now devices communicated in data form NMEA0183. It was mandatory that all devices had to be connected directly with each other. With the new standard, the only thing to do is just to plug the unit into the NMEA2000 data stream.

All easyTRX2S devices with the appendix “N2K” do have an internal converter that is converting NMEA0183 into NMEA2000 and forwarding the new data form into the NMEA2000 network.

The easyTRX2S-WiFi receives the incoming AIS data sent by commercial vessels (Class A) and pleasure boats (Class B). These telegrams are processed into a NMEA protocol which can be interpreted by chart plotters or PC software. With the wireless link to your mobile device, these data will promptly be received there as well.

The easyTRX2S-WiFi transmits according the AIS-Class B standard all own AIS data like ship name, speed and course over ground, etc. to every AIS receiver or transceiver within its radio range. Using the easyTRXS2-WiFi is the simplest way to make yourself visible to others, having all necessary information about your surrounding too.

Running the “easyAIS” App, you will see a radar screen appearing, showing all received AIS targets within range. A click on a target will provide you detailed information about this specific target, such as ship’s name, speed and course over ground, etc. Additional information about your own boat’s navigational status like your own speed, course, wind, etc. are available through sub-menus of the App, if you feed the easyTRX2S-WiFi built-in multiplexer with boat information.

What is needed to run the easyTRX2S?

The Class B device needs a separate GPS antenna and an own VHF antenna. As an alternative you can run the easyTRX2S with the VHF antenna switch easySPLIT-OCB to use your existing VHF antenna. A separate GPS antenna is still needed. Another alternative is the VHF/GPS combi antenna.

easyTRX2S and gadgets that fit together

Your PC has to work at least on WIN XP SP2 and screen resolution  1024*768 for configuration. Plotter or PC software have to be compatible with AIS to display incoming AIS data on the screen. A MMSI number is required to broadcast data – you will get it from German “Bundesnetzagentur” or the competent authority on your country. Your distributor will program this number on your easyTRX2S.
