2.2 Updating the software

The Teldat-3Ge-USB firmware can be updated to newer versions. Please contact your dealer for further details on
new versions.
The firmware upgrade is carried out through a conventional TFTP file transfer. You need a TFTP server from which
the Teldat-3Ge-USB can download its firmware image. This server can actually be hosted in the current access
router. Both the firmware image and the TFTP server IP address are configured or established in the Teldat-
3Ge-USB on startup, during DHCP negotiation.
