MTX-IoT-XS is a powerful all-in-one solution. Thanks to its set of interfaces (RS232, RS485, USB, digital I/O…) and the embedded MTX-Tunnel firmware that provides the MTX-IoT-XS with a basic router-like functionality, this modem can be used in most of the IoT applications with no need for further hardware, shortening the time-to-market and providing a very cost-effective solution. MTX-IoT-XS can be also programmed in JavaJ2ME, for those customers who want to embed their own firmware on it.
