password. Login using username: icoa, password: icoauser

/tffs0/ directory.
5. To download the checksum.txt file, enter "put checksum.txt" at the FTP command line. Optional: If

6. Delete the old configuration file by changing directory by typing “cd ..”, and then “cd /ram0/” then
Enter “del config.txt”

yourfilename.bin.
