I am a little confused that you can see your sensor device in the device info. When I look at the data sheet I see that your sensor has a RS232 interface.
In the device info you should see something about the USB-RS232 converter (for example FTDIxxx) and not the sensor info. In my case I get the following output (USB-RS232 converter): [image: Screenshot_2013-02-28-22-51-33.png] Not all USB-RS232 are supported out of the box by android. If I remember right the FTDIxxx devices are supported well. A good app to get started is "Sick USB 2 Serial Terminal". Try to open a serial connection with this app first.
