Radar plugin v5.0.0 released

[Plover]

Douwe,
Yes Open CPN is running fine. The radar plug in opens up. It allows me to select radar type Navico Halo A and B. Then it shows the scanning window but never opens the radar window.

I know the radar is working fine because I tested it on my Windows 10 laptop, where it works perfectly.

I will send a logfile later today.

Thx for your response.

Try the right hand mouse button anywhere on the chart. Click Control Navico Halo A (or B). You get the radar menu. Click Window, Hide/Show PPI. All OK now?

Yes, I tried that and it opened up the radar PPI window. But it still says "No radar" and just shows "interface Scanning" on the PPI window.

A firewall may be blocking the radar data. Try disabling the Windows firewall.

We have a new production release out now, see https://www.cruisersforum.com/forums...ed-250046.html

Simrad HALO-4 Pulse Compression Radar or Garmin GMR 1224xHD2.

From both devices there are newer types, than stated in the documentation of radar_pi. Garmin xHD became xHD2 and Simrad has an update at the interface RI11 now RI12.
Regarding the xHD2 I found a thread where there were small problems and understood that they are fixed. Also does anyone have experience with the Simrad interface RI12?


Thanks in advance

HALO is fully supported by the plugin. RI12 is no problem, we should update the documentation.



We do not know if xHD2 works, as nobody has reported on it and if you were to buy it and it doesn't work, you would have to work with us to get it working.

marrimac,
I have decided to go with the Garmin GMR 1224xHD2. Because of Corona i will install it only in a few weeks. I will report if it works or come back to your offer to get it up and running with your help.

Tanks

This might take a while, our Garmin expert is not at his boat. And I am crossing back to Europe in May-July. Be prepared to run packet traces etc.

Hello everybody,


we are going to buy a pc to use opcn and several plugins.


How much power does it need when we want to use it with all the plugins and in common at more than one monitor at the same time?


A normal pc with better cpu and ram for about 1000€ or a high end gamer pc for about 3000€ ?


How much power needs the Halo24 radar picture to bring it on a screen as fast as the radar is delivering it ?


And what brings the radar in the future?


Thanks in advanced

Rooki..
A "normal" PC is more than enough for OCPN.

The power consumption for a specific PC you've to check its specifications.
Generally today a laptop may be preferred due to it's adapted to not use more than necessary battery capacity.
The screen would be the one gadget consuming the most.

For a 10 years old PC of mine the CPU usage for OCPN can be up to 25-30% using high detailed oeSENC charts, double canvas views, some 300 hundreds AIS targets and a radar picture. The radar picture wont load more than 5% of the CPU usage, usually less.

Radar future?? It's not clear for me what you're asking for but generally a broadband radar scanner, like the Halo, is the prevailing type when it comes to low power consumption but that has nothing to do with the PC?

Did you discover the wiring details? If so, could you share?

Do you happen to know if there is some internal maximum number for number of targets?

Tried plotting targets from aishub and injecting self generated NMEA-sentences, pretty quickly saturated my machine and I believe not nearly all are shown. I think I reached a couple of hundred maximum.

Used this to generate the AIS-position reports / NMEA-sentences:

https://github.com/doodleincode/aislib

I tried plotting the same directly with matplotlib, naturally it can handle 100s of thousands no sweat - no need for that but say 500-1000 would be nice to have as an early warning when on a busy sealane

There's no limit in OCPN. But the "AIS target list" sort function is abandoned when more then 1000 targets.

As contributors to AIShub we can receive the complete stream of the hub.


Just for fun we tested it getting more than live 12.000 targets coming in. No issue for OCPN. On a W10 laptop and an ancient MacMini.

This is the same AIS-stream I have tested with, plus some others.

I'll try to recreate this, just to confirm we have the same setup:

- OpenCPN running, no other plugins, just some basemap displayed

- OpenCPN listening on UDP for NMEA

- Another machine listening the AIS-stream(s) with socat and generating one synthetic/fake AIVDM-sentence with python aislib per AIS-target

- Each AIVDM sent as separate UDP packet to machine running OpenCPN

Something I should do / try differently? I can try more beafy host for OpenCPN, but this I tried is not that old, basic fairly recent Lenovo laptop if I remember correctly (remoting, so have to check)
