You can re-push current firmware to a module that you suspect is acting up. So you can re-push 1.9 to it and see if that helps.

Tedbear is absolutely correct (no surprise there) on there being different wiring schemes for 37 pin.

Did you do the sensor config for the new planter configuration?

I'm trying to clarify in my head what swapping you did. You have two modules, two cables, and two planters. That's a lot of potential combinations. I'm a bit confused as to what actually happened.

What I would do if I was standing there would be to take your existing (long term owned) planter, with the module and cable original to that planter and start a field operation. Create a new planting event to verify everything is working properly. Then I would shut it down and swap in the new-to-you module only, no cable changes. Then load an event. You should get a warning that the module serial number is not what was expected. Say ok to this message. If everything loads and displays properly with the "new" module, then we know we have a cabling or configuration error on the "new" planter. If it doesn't load, and/or you still only see 12 rows even after checking the sensor config, then we know there is an issue with the module itself.
