5.2 Software updating
The Teldat H/L can be updated to newer versions. Please contact your dealer for further details on new versions.
There are several ways to update a Teldat router.
The software required to update Teldat routers is supplied in a format known as distribution. This consists of a
single file that contains all the files needed to update your device, as well as detailed information on the content.
The Teldat H/L incorporates independent modules for the Wireless WAN interface. You can use modules from vari-
ous manufacturers, or even various modules from the same manufacturer, depending on the technology used. Gen-
erally the modules’ firmware is independent of the device’s software. There is an UPGRADE file for each Wireless
LAN module. Please ask you distributor for the correct upgrade file for the module in your device. The document de-
scribing the CELLULAR interface explains how to upgrade the module.
