A2.3 Update of the TCP/IP-Stack
Required is a PC running Windows 9x/NT/2000/XP with a
network connection and activated TCP/IP stack. For the update
process you need two files which, as already mentioned, are
available for download from our Web site at http://www.wut.de.
• The executable update tool for transferring the firmware to
the LAN-Modem.
• The file with the new firmware for transferring to the LAN-
Modem.
It is not necessary to do any special preparation in the LAN-
Modem for a firmware update. You only need to close all data,
control and configuration connections.
Highlight the desired LAN-Modem in the WuTility inventory list.
The Firmware button starts the Update dialog box in which you
must specify the file name of the new firmware (*.uhd). After
checking the compatibility of the specified firmware for the
selected LAN-Modem, WuTility activates the Next button which
starts the actual file upload.
