The ClassB unit easyTRX2S receives AIS ClassA and ClassB signals and transmits own data according to ClassB standard.
All devices of the easyTRX2S series are performing with a lot of usefull features:
By means of USB port connection to PC or Laptop is possible. With contained software it can be choosen between 38400 or 4800 Baud data rate. Function activity is shown by 8 LEDs. The easyTRX2S is able to interpret incomming AIS data for CPA alert or AIS S.A.R.T. ermergency messages. Additional the easyTRX2S devices can be used as power surce for external alerting devices. All received and transmitted AIS data can be stored with internal SD Card recorder. With the build-in multiplexer input 3 devices with different baud rate can be pluged to the easyTRX2S units. At least the external cable harness gives the possibility for outsourcing functionaly like "change into silent mode " or "PAN PAN emergency call" by switch.
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 strenght to avoid phisical loss.
The integrated NMEA2000 Adapter enables to connect this AIS transceiver into the latest NMEA2000 network standard aboard.
NMEA2000 is a new dataform 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 dataform NMEA0183. It was mandatory that all devices had been connected directly with each other.
