Below is a link to a ZIP file containing 4 files for updating the DataScout's firmware.  After downloading to your computer, please extract the 4 files from the ZIP file to the root directory of a FAT32 formatted USB flash drive.  Disconnect the battery and solar panel, or AC/DC adapter, from the DataScout.  Insert the USB drive and wait 10 seconds.  Reattach the battery and solar panel or AC/DC adapter. The light will flash green until the firmware is completely loaded. Once it stops flashing, you can remove the USB flash drive.  Data uploads normally resume within 15 minutes but it may take up to an hour for new data to be displayed in SpecConnect.
