You need a AFX cable from outback, plut it into the gps for the monitor and that is all you need. You will have to have the outback S in the combine also. I have this set up in my 2388.
You will also need a memory card compatable with your yield monitor, so that you can log data. Once all your data is logged you will need a means (card reader or laptop) to get the data off the card and onto your computer that has yield mapping software installed on it.
I have a 110 volt adapter for my YM so I can look at the info in my house. It also has an additional end (computerIJ) that looks like it could be plugged into a RS232 portIJ Have anybody seen this type of set-upIJ Would I be able to transfer the data straight into my computer with the software. Thanks. Jack
