Firmware recovery

Using USB to recover firmware
Via USB, you can reset the netHOST device to its factory settings or, as an
alternative, perform a so-called “firmware recovery”, by downloading a new
firmware file to the device without thereby deleting any existing
configuration files within the device.
For this, you need a USB cable with a Mini USB connector and the Hilscher
ComProX
tool, which is stored on the netHOST Solutions DVD in the
Supplements & Examples\netHOST Device Recovery\Recovery
via USB
directory.
ComProX
can be executed directly from DVD, it does
not need to be installed on your configuration PC.
Note that for recovery via USB, you need to install the USB driver for the
Hilscher netHOST on your configuration PC. This driver allows you to
communicate with the netHOST via USB, even if the old firmware within the
device is defective or missing altogether.
It is recommended to install the USB driver
before
you connect the
netHOST device via USB cable. Use the
setup.exe
driver installation
program for this, which is stored on the netHOST Solutions DVD in the
Setups & Drivers\USB Driver
directory.
The installation of the USB driver is described in the user manual
Software Installation netHOST Devices
, DOC130501UMxxEN,
which is stored on the netHOST Solutions DVD in the
Documentation\english\4.Installation Instructions
directory.
Note the following concerning recovery via USB:
Although any old firmware file that may have existed in the netHOST device
will be overwritten by downloading the new firmware file (recognizable by
the
.NXF
file name extension), all other files stored in the internal load
memory of the device remain untouched. This means that any existing
configuration (
CONFIG.NXD
) or IP address (
NWID.NXD
) file in the device
can be preserved for further use, if needed. However, if you want a
complete reset of your device via USB (a complete reset to “factory setting”
means that only “fresh” firmware is present in the device), you can delete
the configuration and the address files separately in the
Explorer
of the
ComProX
tool.
