Maximum connectivity, maximum economy

STW from Kaufbeuren is expanding its portfolio of communication modules. The newly developed TCG-4lite offers comprehensive performance and connectivity options with the greatest possible cost efficiency.

Networking from machine to machine or machine to infrastructure is one of the central prerequisites for the realization of digital automated processes. In harsh applications in agricultural, municipal or forestry technology as well as in construction and special machinery, communication modules are needed that are protected against environmental influences such as dust, extreme temperatures, vibrations and aggressive media such as fertilizers. STW from Kaufbeuren is a leading manufacturer of automation and digitization components for these machines. Based on the successful TCG-4 communication and telemetry module, STW has developed the TCG-4lite. It offers an economical alternative for machines and applications that do not require the full range of interfaces of the TCG-4.

Nevertheless, the TCG-4lite offers a wide range of connectivity options. Mobile connectivity to cloud services can be realized using the LTE modem in 2G/3G/4G networks. For satellite navigation and location determination, the TCG-4lite supports the GPS, Glonass, Galileo and Beidou systems. The connection to the machine succeeds with two CAN or one BroadR-Reach interface. A 700 MHz single-core Freescale i.MX6 processor is available for data processing and storage, along with 8GB of Flash and 512 MB of RAM memory. The operating temperature range of the module with IP67K protection is between -40 and + 85 °C.

Typical use cases of the TCG-4lite are location monitoring and geofencing of machines. This can be followed by warranty monitoring and verification in the event of faults or damage. Machines can be integrated into any cloud and fleet management solutions via the communication module. On-demand billing models and feature activation are also possible. Remote monitoring and diagnostics can of course also be realized with the TCG-4lite. From fault memory readout, real-time debugging, software and firmware updates to display mirroring - all these functions can be used remotely over-the-air.

With the TCG-4lite's powerful processor and memory, machine data can be pre-processed and appropriately processed signals and measurements can be fed into cloud and telematics services. The Linux operating and development ecosystem with its extensive libraries enables rapid and independent application development. Regular software and security updates ensure a high level of security. The open Linux system enables customers and developers to realize their application and innovations intuitively and user-friendly.
