3.3 Mini USB Connector
The MTX-IND-V2 supports a USB 2.0 Full Speed (12Mbit/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 min 3.0V. They are 5V I/O compliant.
The USB port has different functions depending on whether or not Java
is running. Under 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.
The USB I/O-pins are capable of driving the signal at min 3.0V. They
are 5V I/O compliant. To properly connect the module’s USB interface
to the host a USB 2.0 compatible connector is required. Furthermore,
the USB modem driver delivered with the MTX-IND-V2 must be installed as described below.
The USB host is responsible for supplying power to the terminal USB interface, across the VUSB_IN line.
There are drivers available for Windows environment applications. Visit MTX-IND-V2 ftp at:
