- Model TC3G - Telematics Platform


In addition to wired communications interfaces such as a digital input and a digital output, 2 x CAN, Ethernet und RS232, the ESX-TC3G also provides a USB interface for service purposes. For data exchange via radio, an optional 2G/3G mobile radio connection, WLAN and Bluetooth are available. The ESX-TC3G is equipped with a GPS/GLONASS receiver for position determination. The ESX-TC3G is available in two different antenna versions, with integrated antennae or connections for external antennae.


The version with internal antennae achieves the IP protection class of IP67 and IP6k9k due to the SIM card slot integrated into the connector.

The ESX-TC3G can be deployed for many applications from the simple data logger, which wirelessly transmits the recorded operating data, right up to the central communications gateway, which unites very different communications standards. The hardware plays most on its strengths where the requirements for tightness, vibrations and temperature are at their maximum.

The open source-based Linux operating system for the ESX-TC3G provides the ideal basis for creating complex applications in a fast and uncomplicated manner. No further costs are incurred for licenses or expensive development tools. The development environment for the ESX-TC3G is based on freely-available tools. Various examples and documentation facilitates entry into the world of the ESX-TC3G.
