tor – Inside

tor is available in various modules to cover the requirements of a wide range of application scenarios. Different user levels allow the OEM to define the functions for each user.

The basic version contains only the software of the device manufacturer STW. From us you receive a fully equipped setup (tor) with which all the needs of a modern telemetry solution can be covered.




Kits with modules

All tor functionalities are implemented in a variety of modules and are completely installed on the system. Depending on the current authorisation level, various modules are made available or partially or completely blocked. A module always represents a summary of programmes (apps) and data that are required for an area of application. Details on the application area and the functionality of a module can be found on its page.
