Hi, i am thinking about buying a control box from agopen.shop, I have an AgLeader GPS6000 reciver with good accuracy, and it also provides radar pulse so I would like to keep that. Is there a way i can set up the pcb/box to accept a D9/RS232 serial port to feed gps into it?
It will be installed in a Chamberlain 4080, an Australian tractor loosely based on the 30 series deere. Cheers 
Yes that will work fine. You might need some slight changes to the firmware depending on what serial port it’s connected to.
What is the rest of your system? DC motor, Hydraulic, Keya motor etc
It will be steered via a keya motor. I have a usb to RS232 converter, that should be fine for feeding gps into my computer for it?
You really need to connect to the AIO board and have a IMU fitted to that board. Otherwise there will be no roll correction.
I plan to fit an IMU and likely an f9p later down the line, im not super experienced with this sort of thing so want to be able to make it work, before i make it work better. What is the recommendation for an IMU?
@camritch we (agopen.shop) can set up the boards to have RS232 connector on them.
I usually set Baud rate to 115200 and output GGA , VTG, RMC
!! Only F9P could be configured to output GPGGA UM982 can only do GN messages that some manufacturers doesn’t accept.
I usually solder a wire to RX (and if needed then GND as well) and wire it up like that. Would be nice to have this DB9 on the front plate but there’s literally no place for it. Maybe a jack or similar connector could be added so the DB9 connector could be wired easier and ready-made extenders could be used.
There’s also free pins on the Ampseal which means in theory the wiring could be connected there too.
( Please ignore the thermal paste 
UM982 was quite new at the time and this was my way to pull heat away, which despite the looks does work.)
The same approach could also be wired to accept external RS232 signals. AIO can even send RTK corrections to AgLeader 6000 if it accepts such on that port (and I guess needs unlock)
Some customization in the firmware is needed as AIO by default looks for 460k baud rate but your agleader is likely 60 or 115k baud rate.
So how would i go about wiring into the ampseal to accept an db9 on the wiring loom side of things? I think the baud rate for my agleader 6000 is 19200, not sure if that matters, i really am a beginner when it comes to this!
There are some pins that can be jumpered directly to teensy so either using some dupont cables or perhaps soldering some cable to the back of the ampseal
For RS232 we only need 1 wire if we want to receive data. But honestly I’d simply put a DB9 connector on a short loom then you can use regular RS232 extenders / gender changers, etc.
Is there a way to export the correction signal from a AIO4.5 board with a um982 to a CNH pro 600 over rs232? i see guys exporting with a f9p but has anyone tried it with a um982?
