FAQ: easyAIS 2nd. Gen.

FAQ: easyAIS 2nd. Gen. >>>

With the integrated multiplexer in our easyAIS it is possible to connect all external NMEA data sources with 4800 baud and to up convert these to 38400 Baud. With regards to the data source type there is no restriction.

Yes, all the NMEA and GPS input data with 4800 Baud are passed through and upconverted to 38400 Baud. (Together with the AIS Data)

If the red led is flapping, the EasyAIS is receiving telegrams. The range of AIS could be up to 20 – 25nm under good conditions. If no target is nearby, you will see nothing flickering and nothing on your plotter screen.

1) Passing through of further NMEA data: The data is passed through only in one way that means pc data do not go back through easyAIS into the GPS.2) Reduction of the baudrate: it is generally o.k. Many of our customers are using the lower baudrate of 4800 because of different facts. To do that we have had a jumper on the board in the first generation of easyAIS products. Now we do it by a special start up procedure which is described in the manual of the easyAIS 2nd generation. But it takes a little bit longer with 4800 baud until you have all data on your pc.

The typical result of the lower baudrate: For example if you have 160 targets (at the moment we know the Rotterdam harbour is the only one which has such a high number of targets) With 4800 Baud it takes about 40 seconds until you get all the dynamic data onto your display. If it is no problem for you to wait to receive the objects onto your display, you can use one port with 4,8 kB. But if you would like to have the objects in real-time you should prefer to use maybe a 2nd port where you can get the easyAIS NMEA data by 38400 Baud.

Both versions (A and B) of transmitters work on the same frequency and – what is more important – they use the same transmission protocol. The difference is the content of the telegrams – not how these telegrams are transmitted! Therefore: Our easyAIS is of course able to receive Class A and Class B data. No problem for that.

In the past we hear from several persons again and again, that the easyAIS cannot receive Class B telegrams. The only short and clear answer we can give is: It`s wrong.Please look again onto our homepage at the point: “AIS Capability”and read the difference between Class A and Class B transmitter. The telegrams and the frequencies are identical. If you receive a class A transmitter telegram, you also receive a class B transmitter telegramm. Do not be unsettled by such statements.

Summary: Of course, you can receive telegrams of a class B transmitter by an “easyAIS”!

Our integrated multiplexer is converting NMEA 1083 signals from 4800 Baud to 38400 Baud, not depending whether it is a GPS or another signal. If you pass your fast heading signal through to our easyAIS into your C80, everything will work smoothly. (It works for one unit from which the signals are passed through to the NMEA input of the C80.)Please don’t forget to configure the NMEA input at your plotter to 38400 Baud. You do not need a multiplexer at all.

Yes, the latetest generation of the Navman Plotters are easyAIS compatible.

With reference to the cable we did following:The exsiting cable is already 5m long. We tested the VHF/GPS combination antenna with an additional 10 m long cable. At the end the total cable length was 15 m. The additional cable was a simple RG58 cable. It had a male TNC plug and a female TNC plug as extension plugs between the existing cable and the TRX. The plugs were crimped to the cable. This worked very well. All the satellites in our hemisphere were visible.

Therefore we can guarantee a 100% working for a cable length of 15m with RG 58. But as you know as better the cable is, as better the reception and transmission will work.

Unfortunately, your suggested way does not work. It is not possible to connect with an USB plug.
The reason for that: serial and USB use different levels for data transmission. Also Windows needs a driver for every USB connector.

The solution for you will be this: You solder a sub D-9 connector onto the cable. The connector goes into a serial<->USB adapter. And you attach this adapter into the pc. We can deliver a SUP D 9 pole connector and also an adapter.

FAQ: easyAIS 2nd. Gen. >>>The easyAIS can be connected with a pc (this is also in the manual on page 12).

Connection of the easyAIS to the pc: Please connect the white-orange cable with the pin 2 of the SUB D 9-pole connector (female) and the orange cable with the PIN 5 of the SUB D 9-pole connector. It is very urgent, that you take the right PINS. They are hardly readable at the plug, but they are signed. After that, please install the USB serial adapter on the pc. Then you can connect the SUB D 9 connector with the adapter.

Please note the interface must be configured correctly: 38400 Baud, 8/N/1.

Yes it works very fine. We are located near by the rhein-main-donau-canal, 9km distance and we do daily continuous receive 8-15 AIS objectives in the canal. The barger do not uses an other “AIS” as the navy. The method is standardized.

It is possible with a special telegram.

The Message 22 by the class B AIS can stop temporally the transmitting a base station of a coast radio station. (It also can switch the transmitting telegram from all 30s to f.e. every 60min or even longer, if needed). The class A transceiver on the ships can not do that. Class A sender can not manipulate a class B sender. But there are difference ECDIS-electronic chart display information systems (norm EN61174) on the commercial shipments which does join with the class A AIS by it can inhibit the class b sender via filter function on the ECDIS display

Both versions of transmitters (A or B) are working with the same frequency and what is more important, they have the same transmission-protocols. The difference is the content of the telegrams, not the way the telegrams are transmitted.

Therefore our easyAIS is certainly able to receive class A and class B data. So this is not a problem.

To get AIS/GPS data by WiFi on your PC some navigation softwares need a COM port.
Now you have to send data from TCP/IP (from WiFi-Board) to your PC.
This is done by a VSPE-Tool (Virtual Seriell Port Emulator).
We use it from www.eterlogic.com

We recomment to download the file from our page here(WiFi-COM-Tool)
as we already gave the right settings there for you:
https://www.easyais.com/downloads/software/software_allgemein

Please unpack this zip file and start the setup procedure.

After this you should see an icon on your desktop, please start this.

After a few seconds a green symbol is seen below right of your desktop.
You an click on this to set more settings.

If the window is empty you can load the right settings which are also contained on this ZIP file.
This is called config-V1.vspe or config-v2.vspe.
V1 is only used in old WiFi modules. So please try v2 first.

When you need further assistance you can send us an email to support@weatherdock.de
