STW Technic ESX-TC3G

A Linux Operating System, an Extensive Board Support Package & a Telematics Application Framework that Provides Powerful Tools for Telematics.

The STW Technic ESX – TC3G is the latest addition to STW’s Telematics line with 3G and CDMA.  It is based on the highly successful STW Technic ESX-TC3 controller. The major enhancements are the addition of 3G and CDMA capabilities to the existing GSM modem, the addition of GLONASS to the GPS for faster and more accurate positioning and the presence of both internal and external antennas.

The ESX-TC3G will have the same 32-bit MPC5200B 400MHz processor and 1GB of flash memory as its predecessor. The unit has an excellent array of communications options.

The basic unit has two (2) CAN ports, an RS-232 port, and a USB port. The communications expansion board adds a digital input and output, an accelerometer, and the option to add cellular (GSM/CDMA/3G), GPS and WLAN modems.

Antennas can be internal or external – the TC3G is one of the few telematics units on the market with internal antennas. The internal antennas and a patent-pending design incorporating the SIM card into the connector allow the TC3G to meet both IP-67 and IP-69k environmental standards.

The TC3G is robust and designed for working machines and highly challenging environments. This telematics control unit is suitable even for sophisticated control and gateway functions. For example, it can be used for agriculture machines, snow plowing vehicles, and other mobile machinery.
