Re: OpenCPN SIMRAD/LOWRANCE Radar Overlay PlugIn

Hi Dave,
Just got back from 2-months in the Lau Group and out of contact. Just an update for anyone who is interested. I've now got a working plugin for the KODEN RadarPC. If anyone has the same type of Radar and wants to test or get involved then let me know.
Cheers,
Mark

Re: OpenCPN SIMRAD/LOWRANCE Radar Overlay PlugIn

Download latest version here opencpn-navico-radar-plugin.github.io

Same issue for me. Took my other laptop down to the boat today to try that. Same thing again - no radar picture on this plugin .

I'm now thinking it must be a conflict with something - I'll delete and re-install windows (7) on my nav laptop, then install only OCPN and see what happens....

Re: OpenCPN SIMRAD/LOWRANCE Radar Overlay PlugIn

Update - no radar pic with latest (2) plugins; I have deleted Windows, reformated the disk drive, reinstalled WIndows 7 Ent edition, patched up to date, downloaded and installed OCPN 3.2.2222, installed charts, and the plugin BR24 Version 0.41026. Still no radar pic. This laptop is an Asus X42F, with Intel graphics.
If I regress to earlier plugins it was ok, but when I formated my disk I forgot the only other copy of the August version was on that If anyone can send me a copy I'd appreciate it!
So, what changed in the DLL between August and now?

Re: OpenCPN SIMRAD/LOWRANCE Radar Overlay PlugIn

Matt..
Frustrations, for you and me because I can't make much of a help. Have no ideas since the 41026 version is working on my Win7 using BR24 and for Douwe using 4G as well. I suppose you have checked the log file for any traces? A silly? note but yesterday I couldn't get my scanner working but it turns out to be due to the lack of neither compass heading,HDT, nor GPS course, COG. I'd forgot to switch the compass on! (If I remember right some earlier plugin version still viewed a, face up, radar picture even without any of them.)

I've attacked two zipped versions, 40622 an 41026 both built by me against most recent OCPN beta. The latter is the one where Kees have changed the ageing logic and the menu behaviour but I think you've tried it. Please download and scrap the .pdf extension

Re: OpenCPN SIMRAD/LOWRANCE Radar Overlay PlugIn

RI-10 interface box

May be a little bit of a side track from the pi, but still interesting. In Europe the Lowrance radar is supplied with a RI-10 interface box. This box connects to the radar with a RJ-45 connector and to the official display with a Simrad proprietary ethernet connector. There is also a Simnet connector for a NMEA2000 connection. The box will accept heading info from the NMEA2000 and pass it to the radar for Marpa and chart overlay. Currently this functionality is not used in the pi.
I expected that the RI-10 would pass the heading info over the Ethernet to the radar. Actually it does not.
I found that the RX and TX wires of the incoming ethernet (RJ45) are directly galvanic connected to the outgoing ethernet (Simrad connector, pins counted clockwise looking onto the RI-10) as follows,
RJ45 pin1 (white/green) to pin 3
pin 2 (green) pin 2
pin 3 (white/orange) pin 5
pin 6 (oranje) pin 4
This means that the incoming NMEA2000 data is not intermixed into the ethernet.

Instead there is a signal on pin 7 and 8 (brown, brown/white pair) of the RJ45. This is not an NMEA2000 signal, there is a a differential voltage of 5 volt, could be a RS422 signal. I have not succeeded in further analyzing this signal.

Summary: the incoming and outgoing ethernets are directly connected. Over a spare pair of wires the radar receives the heading info.

Re: OpenCPN SIMRAD/LOWRANCE Radar Overlay PlugIn

Hakan, ok, the older .dll works (sort of - see below), the newer one does not. Let me give you some further background. Earlier this year, I lost radar pics below about 1nm. Kees had a similar problem, and it was a fault in the radar, so after trying various .dll versions, I decided I must have the same fault, as no-one else had reported it. Being a bit low on cash at the moment, I decided I had to put up with it for a while.
Then, in August or Sept, another user commented to me that he had had a similar issue, and it was resolved by a newer .dll. So I looked on GIT, and downloaded the latest (remember, Sept at this point). It worked! I had all ranges again, and I thought "fixed!, something in the .dll..."
Then, I noticed the latest one had come out - changed to that. No radar image AT ALL... Changed back to the Sept one, worked. No other changes. Tried it on my netbook - same results exactly. So I decided to format and rebuild my nav PC to see if it was some other software app conflict, or a windows problem causing the issue. I formatted, and rebuilt windows (7, ent, SP1) loaded OCPN and charts, Still no radar Pic. Stupidly I had formatted the machine with the Sept .dll on it - the only one that worked properly!
It does not seem to be hardware - changing the .dll's gives repeatably no radar image at all with ver .41026 and an image with range over 1nm with .40622. There is nothing obvious in the log files;

.41026

Help on Radar Overlay PlugIn

Hello, I am quite afraid to ask this, but no question, no reply ;-)

Being very fed up with my ancient Raymarine setup (approx.year 2000, when they went bancrupt and that reflects how the components perform, work together or fall apart) and following the progress of oCPN I think time is ready for a fully working PC-backup and later changeover. A direct access to NMEA2000 might be helpfull, but this is another topic.

Question is: Garmin or which Navico or what else?

Raymarine was only once asked for in this thread, I asume no one works on a fork to include their new scanners (Broadband, not my old stuff)

Garmin does not convince me as once I decide to go for a chart plotter I am stuck to Bluecharts. Sailing in Asia and later to EU this might not be the best choice.

Navico (Simrad, B&G and Lowrance), do their Radar scanners all have same and interchangeable software? Hence it does not matter what G4 scanner I buy? Or is there a specific preference? Again the point is a backup if my PC runs havoc.

Is there anywhere a list of already working features and a possibility to compare with the Garmin solution? eg. Marpa development was denied for Simrad somewhere in the thread, any change of mind?

Thank you for any reply,

Heinrich

P.S. I'll be in LA early Dec. and one scanner I want to bring home ;-)

Re: OpenCPN SIMRAD/LOWRANCE Radar Overlay PlugIn

Heinrich,

I can't comment on the others, but the Navico radars (Lowrance, Simrad, B&G etc) are all the same, one manufacturer (Navico) and different labels. 3G or 4 G both work. Be aware that this plugin is in Alpha code.

Charts - if you are using Opencpn, then the charts are limited to whatever opencpn can display, what the manufacturers radar screens display is irrelevant, unless you want them to match exactly with the PC radar view.

With the Navico radars, you do not NEED a radar display or junction box of any type for OCPN to work - the radar dome ethernet plug can go directly to the laptop/pc ethernet port. Cheaper. You can do a 3G radar for close on $1000 USD....

Good luck!
Matt

Re: OpenCPN SIMRAD/LOWRANCE Radar Overlay PlugIn

Matt or Hakan. If you know the approximate date SEPT you can revert back in git and compile to get the one that works. Test it out then do a diff to see what has changed and might be causing this. I wonder if there are different versions of the software in the radar. Perhaps you updated the radar software. Not having one yet leaves me at a disafvantage.

I can post the git steps to revert if needed.

Yes please Rick, I'm new to GIT, and have never compiled anything!
Thanks
Matt

BR24radar_pi release 0.41102

I’ve been improving the plugin over the last few weeks, and just pushed release 0.41102 out to the download site.

Important fixes:
  • Ageing of the radar image and drawing has been revised.
  • Robustness when radar data is sent in incomplete, longer or shorter packets than normal.
  • Overlay of the radar image during scrolling, moving, zooming, etc. works better.
  • Added missing radar controls: Target Separation, Noise Rejection, Scan Speed.
  • The radar control is shown when you click on the radar button.
  • Master mode is enabled even when the radar was already on, so you can take over from a 2nd control unit.

The image is now as good as or even slightly better than on my Lowrance, as the computer has a higher resolution screen.

I’m still working on having the controls on the screen update when you adjust the radar image on a different control unit — whether a 2nd OpenCPN instance or a MFD.

There is a ‘hidden feature’. If you set VerboseLog=1 in the ini file then the “Advanced” part of the control dialog will show how many packets and spokes were received in the last refresh (1s unless you are moving/scrolling), and how many are incorrect or missing:

Windows compiled DLL: opencpn-navico-radar-plugin.github.io


Kind regards,
Kees

Re: OpenCPN SIMRAD/LOWRANCE Radar Overlay PlugIn

Matt,

I'd like you to try 0.41103. Set VerboseLog to 1 in the ini file, start the radar (press the radar button) and click on "Advanced >>". Check whether the first "pkt" value gets other than 0.

If it doesn't, check the log file. It should have lines every 3 seconds (if verbose logging is enabled):

BR24radar_pi: received report <x> bytes: ....

My 4g puts out 3 packets of 18, 66 and 129 bytes every few seconds.

Re: OpenCPN SIMRAD/LOWRANCE Radar Overlay PlugIn

Hi Merrimac, thanks for your efforts!

I changed to the new version you supplied. A couple of differences. The radar switch icon never goes green now, stays yellow when on, and red, of course when off. There is no Radar image at all and no packets, no spokes...
Still works if I go back to the old .dll (but not under 1nm)...
Is that any help?

Matt
