When entering the optimizer serial numbers into the Layout step of the online configuration wizard, it can be faster to use a bar code scanner. (Any generic USB bar code scanner should work.)
Click a module in the Layout to highlight the text and scan each bar code in the string from first to last in its proper location. Print a copy of the string list template from the last step of the wizard by clicking the Maximizer Barcodes button and use it to keep track of your bar code stickers.
Note that 2ES bar codes will enter serial numbers for a pair of modules, but only in the configuration wizard. If scanning 2ES bar codes into the .csv template, remember to skip a line where needed.
