Subject: Lost seeding rate and fertilizer flow (seedstar 1 G2 and Greenstar liquid) deere tech is stumped


Hi all, wanted to run this by you:

Planter is a Deere 1770NT 16r30
Seedstar 1 Gen 2

Fertilizer cart has a greenstar liquid controller.

Liquid controller runs to the wedge box, wedge runs to the tractor, there is a terminator after the liquid controller

Voltage at the flow meter is 5v

Canbus voltages are
13 red to black
2.5 green to black
2.5 yellow to black

Seedstar voltages are
12v at wedge box
8v seed sensor

Greenstar voltages are
13.5 at the section valves
12-13, ecu power
Sensor 1 5v
Sensor 2 2.5v
Sensor 3 5v

Both devices were working, but i simultaneously lost both my fertilizer flow data and seeding population data(shortly after cleaning mud out of rows 1,2&3)- both controllers still show on the 2630. Planter is still seeding and putting down liquid.
luck, hooked the controllers up individually, no luck.

The one thing I do see is under control unit info address 0xC0 and 0xC3 show control unit unknown.

Any advice would be greatly appreciated (planter is new to us this year)

Edit: I should add that the speed on the machine matches the 2630, and the results are the same when using a manual speed input
