New radar Halo20+ not able to select on Zeus2

[Nor]

I replaced the faulty 4G radar with a new Halo20+ radar, using the cable adaptor to be able to connect the Halo20 to the 4g's cable. The manual says the RI-10 box can be removed or kept in place without negatively affecting performance. So I kept it in place, without doing anything with the cables.

On the Zeus2 chartplotter it show Radar source: (invalid 4G-620), with no way of removing this old radar.
In sources list I se RI-10 Broadband radar. But no way to select this as the radar.

Anyone met similar challenges when replacing a 4G radar with a Halo20?

One data point -- I did exactly the same operation as you did, and the radar worked, both with the new Zeus 3S plotters, and with the old first generation Zeuses.


I later removed the RI-10 and organized a separate power supply, and the radar continued working normally.


If I were you, I would try removing the RI-10. Then, if that doesn't work, then I would check all the radar cable connections.


Does the radar dome have power? There are LED's to show that.


Good luck.

Thanks. Can I see the leds from below?
I assume RI 10 might show up even if the radar doesn't have a good connection, so I shouldn't rely on that.

The radar dome has a power on LED in the base, which you may or may not be able to see from below depending on the configuration of your mounting bracket.


The Halos also have decorative blue LED's which you definitely can see from below -- if they are switched on. I believe they are normally switched on by default; mine were.


If you don't see anything, then I would focus first on power supply and cable connections.

Thanks, will see more tonight. But I'm in Hong Kong and it doesn't get very dark here with all the neon lights, so not do easy to know for sure if there's some tiny lights up there.

I had similar problems with an earlier gen 3G. Resolved (eventually) by an undocumented hard reset of the display unit

Great, what do you mean by undocumented?

[barryglewis]

I mean not in the installation or use manuals, and the help/ call centre were no help, just advising to swap items out. The accredited dealer who was helping me trouble shoot eventually found it out on the internet!
This was a brand new system, and every item was swapped under warranty before the fix was found No thanks to Simrad / Navico

Is the hard reset a button etc to press? or a software reset? Do you loose all calibrations, autopilot settings etc then?

[Nor]

I tried the hard reset. No the old 4G-620A disappeared but i only says No radar. The RI-10 still shows up in devices. I measured the current going through the power cable to the radar and I see 4.1A, so it's definately getting power.

It seems complicated to remove the RI-10. I must solder the tiny data wires into a new ethernet cable that connects to the Zeus2. I kins of have a feeling that if I go through all that trouble there will be no change.. But I assume it's either that or the data connection in the mast.

My Zeus2 runs software 18.3 that is the newest I can find. Can that be the issue, is it not compatible with the Halo20+? I find conflicting information about if it's compatible or not.

Sorry, bit late, yes, it was push about 3 buttons at the same time.
Is it ethernet from the RI-10? If so,
Have you tried it to a different display, or to a computer with opencpn and radar plug in?

That's an interesting idea, I could plug the ethernet adaptor into the Ri-10. However, I'd have to get a usb to ethernet port adaptor for my computer. I don't have another other display here.
Will see if I can get a cheap usb one.

The end of the radar cable is an RJ-45 male.


Your Zeus has the Navico yellow Ethernet socket.


You have a few choices which don't involve soldering, e.g.:


1. Use the proper Navico cable with RJ-45 socket on one end, and yellow plug on the other. That's what I do.


2. Cut off one end of a Navico Ethernet cable, CRIMP on an RJ-45 jack, connect to the radar cable with an RJ-45 coupler.


3. Cut off one end of a Navico Ethernet cable, cut off the end of the radar cable, and connect the two cables with a telecom junction box (how I did the connection between two Zeuses, which is working perfectly 13 years later).


If I were you, I would remove and sell the RI-10. This device is failure-prone, so there is demand for them on Fleabay. For the same reason, you don't want it in your system. It does nothing useful for you and it is an unnecessary potential failure point, even if it's not the cause of your problems now.

Very good suggestion

Yes, it's Ethernet all the way.

Furthermore, he can connect his laptop directly to the radar cable, bypassing the RI-10. The 3G/4G radar cable has an RJ-45 plug on the end.

Thanks, this made me open the radar connection and realised it ends with a RJ-45! Then it seems not so complicated to get this connected to the display. I will give that a god
