When working with the IPI embedded web pages, the response visible in HTML source code follows this structure:
var file=new Array();
file[1]=“[filename 1],[day, date time1 of upload] GMT,[file size 1 in bytes]”;
]
file[2]=“[filename 2],[day, date time2 of upload] GMT,[file size 2 in bytes]”;
]
file[3]=“[filename 3],[day, date time3 of upload] GMT,[file size 3 in bytes]”;
]

NOTES:
If there is insufficient space on a box to store the sent file, response will be
Fld
]
instead of
Upl
]
to denote
failure.
Updating firmware can be done by loading an .S19 file with this command. If the box determines that the .S19 file is
not intended for this product, the
Upl

response is followed by an
Fwm
]
response (Firmware mismatch).
