Product information

AIS Class B Transciver SOTDMA – Be seen with increased visibility!

5 Watt radiated transmission power, faster transmission rates and SOTDMA technologies – all this benefits contains the new easyTRX3, the new AIS Class B generation from Weatherdock.

The rigid and waterproof housing of the easyTRX3 has up to date plug connectivity for NMEA2000, 3*NMEA0183 as well as USB.
The Class B transceiver can easily be configured at home because power supply is given via USB when connected to the PC. It is the same with the internal storage: no external power supply for read out the data.

The easyTRX3 is working with SOTDMA technologies. This means that the device scans for used time slots and will reserve available slots for own transmission. Other AIS Class B units are informed that this slot will be used also for next transmission as well. Thanks to the increased radiated transmission power of 5 Watt and the subject to speed transmission rate, the new easyTRX3 will increase your navigational work and your safety board – to see and to be even better seen – what else do you need?

MTM - Maritime Text Messenger

The great feature of the SOTDMA method on Class B devices is the ability to send text messages via AIS, as with a Class A device. We call this method MTM, Maritime Text Messenger.

There is a special app for this, with which one connects the easyTRX3. With an easyTRX3 WiFi, the text messages can be conveniently sent and received via a mobile device. Devices without WiFi can be connected via USB via PC / MAC.

The message is transmitted via the AIS message 6 or 26 and can be addressed to a specific ship, this acknowledges receipt automatically. However, the prerequisite is that the opposite is also a SOTDMA device. Only a transceiver with SOTDMA can then also process these messages.

A message can contain 48 symbols. Within a minute max. 61 symbols are sent. Example: “Arrival Marina Portofino, ETA 1800”

Furthermore, a SOTDMA can transmit the AIS messages 8 and 26 to all within reach. So start a broadcast. Here the message can contain 54 symbols. Within a minute, 72 symbols are possible. Example: “Marina Portofino is closed”. This could even be sent by the port itself.
