MTX‐3G‐JAVA Family
4.2 Mini USB connector
The MTX‐3G.JAVA supports a USB 2.0 High Speed (480Mbit/s) device interface. The USB interface is
primarily intended for use as a command and data interface and for downloading firmware. The USB
I/O pins are capable of driving the signal at a minimum of 3.0V. They are 5V I/O compliant.
The USB port has different functions depending on whether Java is running or not. With Java, the
lines may be used for debugging purposes. If Java is not used, the USB interface is available as a
command and data interface and for downloading firmware.
To properly connect the module's USB interface to the host, a USB 2.0 compatible connector is
required. Furthermore, the USB modem driver which is delivered with MTX‐3G‐JAVA must be
installed as described below.
The USB host is responsible for supplying power across the VUSB_IN line to the module's USB
interface. This is because MTX‐3G‐JAVA is designed as a self powered device compliant with the
"Universal Serial Bus Specification Revision 2.0".
The MTX‐3G‐JAVA cannot be powered by a USB port. If you need this feature, contact
gsmsupport@matrix.es. Only modems that have a mounted internal Li‐Po battery (‐BAT) can operate
with USB power voltage.
There are drivers available for Windows and Linux environment applications. Visit the MTX‐3G‐JAVA
