In the Info page of AS2012 add a chart from the available charts (just start with chart 1).
From the Aquaero, select the "data log" and chose your data source (using the button menu), the available options (it will be a bit more intuitive if you name them within AS2012). Use the "save" button (floppy disk) to write to the Aquaero. Wonder if some folks are wondering what that the icon is. LOL
