7920 with 2630 losing connection to rate controller on 1770nt
I have a 7920 with a 2630 display running a 1770nt. We have used this setup for about 7 years. This year it is randomly losing connection to the rate controller and the rate controller disappears from my screen but then I can still see it in my tab for selecting windows so it knows it's there. If I go back and unplug the isobus and replug it in the controller returns snd works again. I'm also randomly getting an error that my controller isn't set up for prescriptions but then it seems to be planting off the prescription just fine.

You might try replacing your can terminators on the tractor or there may be one on the planter as well. I used to be a JD Field tech. The where a common item to replace when you had communication issues. There is an active and a passive terminator. One is behind the radio and the other is out in front of the radiator I think. Most Deere dealers keep them in stock. Think there called diodes in the ...

Thanks for the reply. I should have mentioned that is one of the things we tried.
I hope I don't come across as an idiot, but I've had luck with some of these types of things by allowing the tractor to fully power down, and flipping the dead-man switch for a few minutes (if it has one). 70% of the time, that cures it. Otherwise, I've had several times where a pin inside one of the connections isn't seating correctly, and it's not getting consistent contact. Those would be the ...

thanks for the response. Ya we tried to simulate it by pulling on wires and bouncing them around and couldnt get it to happen. I really dislike electrical issues they can be so difficult to diagnos. I tried a cold boot of the 2630 as well with no luck. Some times it happens on each end of the field and sometimes i can go an hour with no trouble. I called John Deere tech support on the stellar supp...
Another example. This popped up rate controller disappeared put it in park to post this and it reappeared

hope you are having better luck. One suggestion I would have is to check battery grounds on the tractor. We had an 8335R that had some controller grounds under the rear window panel on back of tractor. They had gotten corroded and caused intermittent problems. Seemed to happen when we lifted the planter out of the ground at end of field. There should be a terminator on end of rate controller harne...
Had the same problem for several years, dealer replaced the female canbus connector on the rear of tractor and solved the problem.
