A.2 Updating the software
The Teldat H2 Automotive router can be updated to new releases. Please contact your dealer for further details on
new releases.
There are several ways to update one of our routers. For further information, please see manual “Teldat Dm748-I
Software Updating”.
The software required to update one of our routers is supplied in a format known as distribution. This consists of a
single file containing all the files needed to update your device, as well as in-depth information on the contents of the
files.
The Teldat H2 Automotive router incorporates independent modules for the Wireless WAN interface. Generally, the
firmware for the modules is independent from the router software. There is an UPGRADE file for each Wireless LAN
module. Please ask you distributor for the correct upgrade file (according to the module in your device). The Cellular
Interface manual (Teldat Dm 781-I) explains how to upgrade the module.
A.3 Connecting to the device
There are two ways to access the CLI:
• Through the AUX connector.
• Through the Telnet protocol.
A.3.1 Connecting through the local console (AUX connector)
Teldat H2 Automotive has a DB9 female connector on the rear panel known as AUX., which provides access to the
device’s CLI or operates as an asynchronous serial port. The behavior of this interface must be pre-configured. By
default, this interface is configured in local console mode. This section only focuses on the local console mode.
