Re: OpenCPN Radar Overlay PlugIn

Hello,

I am new to this forum, but when I read about this project, the gradar plugin, I was very interested. After that a friend of mine bought a Garmin HD18, and I tryied to help him to get the plugin working. I got as far as successfully connect the radar unit to a Toshiba laptop, using a switch at pin 5 to turn on the radar. I am running Linux mint KDE, version 12.10, and opencpn 3.2. I compiled the plugin with opencpn, and all seems to work except the last step. I get the status window with the connection information, "warming" , "standby" (I used the network setup recomended in the instructions) but I am not able to get the green light of the gradar icon. It stays on "standby" and I don't get any image.

Could you help me?

Thank you very much for your time.

Joo Bispo

Re: OpenCPN Radar Overlay PlugIn

I think the next step is to use the Wireshark application to look at the network traffic between the computer and the radar scanner. wireshark is opensource and in many linux repos.

Wireshark is easiest to use when there is little other traffic on the net except what you are interested in. You may also filter packets to the IP of interest.
You could capture a session from power-up through attempted activation, and post the cap file here.

I'll try to get a trace for comparison, and post a picture. However, my internet is very slow, and it may take a bit.

Thanks for your interest in the gradar PlugIn.
Dave

Thank you very much for the reply. As soon as I capture traffic with Wireshark I will post it! One thing I forgot to mention is that the prefernces window is blank, should it show something?

Thank you again,
Joo Bispo

maybe you need to rename the file .doc to get around the forum technical limitations?

Re: OpenCPN Radar Overlay PlugIn

Anyone know if this plug in will work with a FURUNO Model#R112-8171?

Re: OpenCPN Radar Overlay PlugIn

Hi all,
I posted on a different thread the following:

After playing with a new Simrad NSS I discovered that the Tier1 service built into the unit's GOFREE is readily readible by OpenCPN. In the OpenCPN Connection settings all you need is the TCP/IP address assigned by your DHCP server with port 10110 and voila the NMEA data streams in. This feature even works with WIFI linking. The Tier1 tookkit is at
GoFree Developer Toolkit - Simrad Yachting . Since the Lowrance system uses the same feature this is probably also functional for their latest units.

You can follow it all there. It's not really radar related but does use the Ethernet connection that also carries the BR/3G/4G signals. The MFD is needed to translate the NMEA0183 and NMEA2K serial data to the "TCP/IP NMEA" protocol (which is just 0183 in a packet). One problem is that WIFI doesn't have the bandwidth for the raw radar data and so only the NMEA is useable in a WIFI connected OpenCPN system.

Re: OpenCPN Radar Overlay PlugIn

Radar people...
The time has come and I implemented support for NMEA TLL and TTM sentences.
BUT, there's a BUT.
Before commiting this stuff, I need real recorded data from a real radar to do some testing and tuning (there are no radomes in my living room, the living room is pretty far from any port and mrm's simulator, while being pretty nice, is based on the almost zero knowledge we have about what real equipment produces...), so please turn on your toys and VDR plugin or whatever else you like to record the NMEA stream and get some real data for me, please...
I'm especially interested in the target acquisition, target lost and similar events which have to be handled somehow.
If someone is really curious about how it's done for now, check https://github.com/nohal/OpenCPN/com...68f0665454a5e7 - be warned, this is not production ready, that's why I'm asking your help...

Thanks

Pavel

Re: OpenCPN Radar Overlay PlugIn

Nohal, this is a good request and it is great progress!

It would be useful if you could make the best recorded data you get, available for others to download and test too. (maybe as part of the githup, or on another site) We don't all have radars at the house and may not have current radars that allow recording. Thanks.

Re: OpenCPN Radar Overlay PlugIn

ok, just for those who are interested. I have just bought and installed a Lowrance 3g radar. Install is simple - no MFD - direct to the PC from the radar. I did make a crossover cable connection because I'm not using a hub. There are (other than the data cables) 4 additional wires. Red is +, thicker black is -. Apply power to yellow to turn on. The Thin black is a shield - connect to -.

Switch it on it will go. You need to set a scale in the .ini file, under BR24RadarRangeCalibration=0.35 (its 1 as a default, mine needed 0.35 to scale correclty).

That will give you a working, low cost digital radar

I have access to the boat every day - can record any data anyone needs for anything....

Re: OpenCPN Radar Overlay PlugIn

NZ8720...
We are still in need of a recorded stream of NMEA TTM/TLL messages, especially covering acquisition of a new MARPA target, lost target etc. events...
If you could be the ONE, I would greatly appreciate it as I really want to commit this stuff before I forget what it is and why I did it

Thanks

Pavel

Re: OpenCPN Radar Overlay PlugIn

Hi Pavel,

I'm a novice at this stuff! The radar itself produces NMEA sentences? I thought it would just be TCPIP packets, but I guess the packet could contain NMEA data. If I remember correctly, Dave C said I might not get this with my config as no MFC...
If it does, I'll get them for you. I have wireshark, so I'll have a look at the output

Cheers
Matt
