Assuming you already have a CF Card Reader, in Op Center go to the More Tab, in that menu choose John Deere Data Manager, follow the prompts to download it, once finished you will have a Data Manager icon on the desktop, with the CF Card in the card reader open the Data Manager, you will need to signin with your Op Center credentials, once the data Manger is opened it usually will search and find the CF Card data, if not you may need to browse to pick the correct drive , then it should find the data, then click on the Upload button and let it run.

If any of the data that is on the card is already on the computor the data wont show, in the data manager there is a check box to Show previously uploaded files.
