I think I understand the difference between the two application programs: the Viewer and the Data Logger. Two questions:
1) Is FTP function sending a graph or just the data?
2) According to the s/w description, the Logger requires an audio cable to the computer. (This seems so 1980s.) Doesn't the GC retrieve the data over the USB port? Or is the audio port in case you don't have a USB port? Confused.
