Okay Thomas, I added chart one to the file and I've now got charts in my window. Why? Don't know.

Hi , everybody
Does somebody use the COMAR AIS-2-USB device with OpenCpn ?
Is it compatible ?
Many thanks for your contribution

I have been using the COMAR AIS-2-USB with OpenCPN for about 6 weeks.
It works fine.

Chuck
Thanks for your answer . You relieve me , I've ordered one
Just one more question : how did you set AIS data port , as there is no com port n° ?
Jean Pierre

[ChuckSK]

Jean Pierre
The USB driver creates a virtual com port that causes the USB device to look like a standard com device. The virtual com port appears in the AIS port selection menu.

Chuck
OK , it's clear for me
Thanks again

hello,
I use the latest version.
I compared the reception of AIS target with 2 programs: opencpn and seaclear.
Opencpn not find the "fixed target" such as semaphores to earth, while seaclear yes!

why?

Hi louzou56,
Do you mean lighthouse? (un phare?)

This is interesting.
So in addition to which NMEA sentences sent and received we need to list which AIS targets are handled. (All eventually I hope...)

I'm testing with semaphores Navy (base station).
I had two targets and nothing appears with opencpn!

Hello, I dont know where else to go, I hope this is the right forum for advice. Ive a pretty basic and cheap set up.

Ive one of these:
DigiBOAT
With Windows7.

Im using OpenCPN and have loaded up my CM93 charts. The dongle has its own diagnostic tool, it shows GPS output being logged and gives me an accurate position.
The dongle is NMEA 0183 capable.
The OpenCPN is configured on the same com port as the dongle and the NMEA stream shows a regular feed in, but only the timestamp is inteilligable, the rest of that GPS data stream is similar to a garbled stream of Ascii characters.

The upper right window where the chart name is, is coloured pale red, showing that the GPS is not quite configured correctly.

If I click on the auto follow, it doesnt locate my yacht.

Any ideas what I need to do ?

Many thanks,
Mark

Which operating system are you using?
win xp/vista/win7 ??

Best is if you can open a terminal session and check the incoming data. Use hyperterminal or download something like e.g.
tera term (Tera Term - Wikipedia, the free encyclopedia)

Point it at the com port, set it for 4800bdr and observe the NMEA strings. If they are garbled there is some problem with the com port settings or the device. If everything looks fine and you still cant get a fix in OpenCPN post the output of the terminal window here.

Hello Jonas,
TTermpro - that brings back memories :-)

Ill keep looking, but in the meantime I am on Windows7 and here is a sample of the output from the com port.

Ive then tried reducing the buffer sizes and also switching of the FIFO buffer altogether.
The manual for the dongle states that it works at 38400 baud. Which I have treid and also 4800 as per your guidance with TTerm. Both resulted in highly similar outputs.

Sp then I set the TTerm and the dongle to work at 38400 then I get a sensible stream into TTerm. This looks like the stream that the diagnostic tool (which came with the dongle) shows.

For example...

So, does this mean, that OpenCPN cannot work at 38400 baud?

I also tried setting the dongle to work at 4800 baud with OpenCPN, the datastream is still garbled.

Regards and many thanks for getting involved.

Jonas - update.
It seems that whatever I set the dongle to work at makes no change.
However, if I set Tterm to work at 38400 then I can see the output.

Examples:
Dongle set at 4800, Terror Term 4800

Excellent news.

After receiving first class support from the manurfacturers of the dongle in the USA I got a patch for thier dignostic utility which enabled me to set the baud rate of the dongle to 4800.

OpenCPN located my yacht immediately and I have a sensible stream of GPS data as well.

Jonas, thanks for your help!

Very very happy about it.
