AIS Class A and Class B

Introduction
What is 'IS'?

The abbreviation “IS” stands for “integrated splitter”

If you already have a VHF radio antenna aboard, you can use the easyTRX2S devices with the appendix “IS”. This splitter divides the different signals for AIS and VHF radio out of the marine band. The built-in pre-amplifier increases the signal for not having a loss after split. You don´t have to mount a special VHF antenna for your AIS ClassB unit.

The following devices have the “integrated splitter”

What is 'IGPS'?

 

The abbreviation “IGPS” stands for “integrated GPS antenna”

The easyTRX2S units with the appendix “IGPS” contain an integrated GPS antenna with 50 channel receiver. These units are designed to be used on polyester boats because there is no GPS interference. The Class B can be mounted under deck but above sea level.

By means of this integrated GPS antenna, a separate mounted external GPS antenna is no longer needed.

With stainless steel boats as well as Kevlar and aluminum boats these units cannot be used. In such cases an external separate GPS antenna for the Class B unit is mandatory.

The following units have the “integrated GPS antenna”:

What is 'N2K'?

 

The abbreviation “N2K” stands for the new NMEA2000 data form

NMEA2000 is a new dataform which enables to plug different devices in a row on the data stream. Each unit 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 to be connected directly with each other. With the new standard the only thing you have to do is plugging the unit into the NMEA2000 data stream.

All easyTRX2S devices with the appendix “N2K” have an internal converter which is doing NMEA0183 into NMEA2000 and forwarding the new dataform into the NMEA2000 network.

These easyTRX2S units do have the “integrated NMEA2000 converter N2K”

What is 'DVB-T'?

The abbreviation “DVB-T” stands for “Digital video Broadcasting – Terrestrial”

DVB-T enables to watch TV nearly wherever you want. Create your own sports bar aboard. By means of an internal antenna switched on the easyTRX2S unit with the appendix “DVB-T”, the VHF marine band is divided for the different applications. TV signals within the marine band are separated, pre-amplified and forwarded to your digital TV receiver. This receiver will decode the signal and pass it to your TV set.

These units do have the “DVB-T” module.

What is 'WiFi'?

The abbreviation “WiFi” stands for “wireless connection”

The integrated Wifi module in every easyTRX2S device with the appendix “WiFi” enables to forward all AIS data to mobile devices like iPhone, iPad or Android tablet. By means of “peer-to-peer-connection” the mobile device will get the same information as the cable connected chart plotter.

With our new WiFi function it is possible to have up to 40 clients (terminals). You can simultaneously manage AIS data with multiple devices: iPhone’s, iPad’s and Android.

There is also the possibility to feed AIS data into an existing network, that means you can simultaneously use Internet and AIS on the terminal.

These easyTRX2S devices do contain the “integrated Wifi module”:

What is 'LAN'?

The Term “LAN” stands for “Local Area Network”

It means that multiple devices can be connected in a local network via data cable. The integrated LAN nables the AIS device to directly transmit the data  to a server for the World Wide Web or a local application.

The bandwidth and speed of the data transmission is much higher in LAN than in USB or serial interfaces. Therefore LAN is particularly suitable for working with large amounts of data.
