Plug it into your Combine with the Deere display Find a neighbor with a Deere tractor, combine whatever has a Deere display, go into receiver settings, Serial Output and check all 5 boxes, change the baud to 38,400 and the rate from 1 hz to 5. Restart it and make sure your settings stick, but after that, you won't need the Deere display any more.

You don't actually need all 5 checked, PP requires 3 of them. I can't remember off the top of my head which they are, but all 5 will be fine. It won't confuse the PP display.
