IND780 User’s Guide
Regular maintenance inspections and calibration by a qualified service technician
are recommended. The IND780 is a rugged stainless steel enclosed instrument;
however, the front panel is a polyester covering over sensitive electronic switches
and a lighted display. Care should be taken to avoid any punctures to this surface
or any vibrations or shocks to the instrument. Should the front panel become
punctured, ensure that steps are taken to prevent dust and moisture from entering
the unit until the terminal can be repaired.
Firmware Upgrade Procedure
There are two ways to install an upgraded version of the IND780’s firmware. The
preferred method uses the PC-based InSite™ software tool, but it is also possible
to do so without a computer, using a USB flash memory drive (thumb drive)
connected to the IND780’s USB port.
Upgrade Using InSite™
To upgrade existing installed field units, two upgrade files (Upgrade.L78 and
Upgrade.Z78) are required. These files and the method described below can only
be used if you are upgrading from IND780 revision 3.xx or higher and the terminal
has at least 256MB of CF card memory.
If the terminal has a 2.xx or lower revision firmware or a smaller CF card memory,
the upgrade operation requires a re-format of the CF memory card and a complete
flash of the new firmware files and folders structure. For this condition, contact a
local METTLER TOLEDO representative for assistance in upgrading your terminal.
With the IND780 connected to a network:
1. Run the InSite Configuration Tool (only version 2.01 or higher).
2. In InSite, access Home | Connection I Settings, or click the Settings icon
,
to set up InSite to address the terminal.
3. Access Options | Flash Download, or click on the Flash Download icon
.
From the Firmware Download window (Figure 3-1), select the files to copy to
the IND780’s Upgrade folder. Refer to the InSite documentation or help system
for details on performing this step.
The files selected for download must not be read-only. If necessary, right-click the
files in Windows Explorer, select Properties, and modify their attributes – clear
the Read-Only box at lower left, and then click OK to confirm the change.
