Navico Radar on Mac M1 with OpenCpn 5.10.2

[SVvroom]

Good Morning All!

So last season i installed a new HALO radar and got it working with opencpn via a switch.

Got back to the boat this season and m now not able to get past the "Radar Initializing" stage.

I upadated opencpn to 5.10.2, found the plugin in the beta section, and installed it.

The old TCP connection that i had created in Opencpn is still there, though it seems the most likely culprit for the problem.

I have the radar wired via an ethernet switch. Jjst to confirm, what network address do i put in opencpn for the radar. In the past i went to the system report/ethernet connections and found the address there (192.168.1.242)

The other question i have is what port? Last time i set this up im not sure how i determined what port to enter in the connection window (currently 6878)

Any help would be HUGELY appreciated!

Thanks to everyone!
cheers

There,s is nothing to do in OCPN connections for the radar. Just be sure the PC's wired connection is up for the same network segment as the radar scanner. If a switch and no MFD the radar scanner would DHCP an automatic IP address.

Thank you so much for your reply and help.

Forgive my ignorance, but I don’t totally understand your answer. The radar is connected to a network switch, and then connected to the computer via Ethernet cable. What is the network segment and how do I check or change it ? Thanks so much for any help

Oh and yes there is no mfd in the system

ok, now im even more confused. The radar works on my laptop (also M1 chip but with older operating system) over both ethernet connection and wifi. Yet the main computer doesnt recognize the radar over either.

Ive tried uninstalling and reinstalling the plugin and it doesnt help.

I literally unplug the ethernet cord from my main computer and plug it into the laptop and everything works fine, so clearly the problem is somewhere in my main computer. Now its saying:
"Cannot scan interface 192.168.1.60:Cannot bind UDP sopcket to port 6678"

Any ideas?
Thanks!!!!

My limitations in English can easily lead to misunderstandings but like this:
- OpenCPN connections has nothing to do with the radar. Take that out.
- Connect the radar scanner and the PC to a switch. Leave other connections to the switch out so far.
- Power on the radar and start the radar plugin. Be sure you have selected the Halo radar type. Use Opencpn right click menu to "Show radar" and/or "Halo control". Study the Info window while the plugin searches for a radar. It may take a while.

Good luck

thanks again hakan for the reply

i unplugged the internet router from the switch, so that only the radar scanner and computer are connected. then i restarted everything, and im still not getting it to work.

i went into my network settings and the computer has an ip address

I can literally unplug the ethernet cable from the computer, and plug it into my laptop and everything works fine. Similarly, i used a ethernet to thunderbolt adapter, and it works fine on my laptop but not on the main computer, ruling out a problem with the ethernet port on the computer itself

im a bit at a loss here


thanks for your help

Now it seems to be a MacOs thing? Since I use Windows the most, maybe we can see if there is a Mac specialist here?

[SVvroom]

yes i agree, thank you so much for your help until here hakan

Ok, so i figured out a solution!!!

For whatever reason, i wasnt able to get the computer to connect with the radar over the wired connection. Ultimately, i connected the radar to the wireless router, which allowed Opencpn to connect to the radar wirelessly. Once it had done that, i was able to turn off wireless and the computer rerouted itself through the wired connection to the radar unit!

glad to have gotten that sorted, but still mystified as to how i could force the computer to find the radar without going through such a back door!

thanks for your help hakan. you educated me on some key ideas that helped focus my efforts better

cheers

greg..
Good to hear. I've heard of something similar for Linux, which in some respects is the same base as Mac. That is, that there is some kind of prioritization within the system configuration that determines how wifi and wired should interact or counteract.
I have no suggestions. Others may have?
Thanks for your report.
