URF Use and Installation

Windows Driver Installation

The URF drivers can be downloaded from here.  Download them and put the unzipped ini file somewhere convenient.

Plug the URF in to a spare USB port.  Windows will prompt you for the driver files, so point it at the usb_cdc_driver_cc1111.inf file you downloaded earlier.  Confirm that you want to continue and the driver will be installed.

Windows Device Manager will now show a TI C1111 Low-Power RF to USB CDC Serial Port (COMx) where x is the COM port.

 

URF Use

Plug the URF in to a spare USB port.  Note that depending on your set up, you may get good performance from plugging the URF directly in to the computer.  If you are not able to get the range you need, try using a USB extension lead to get the URF away from anything likely to interfere with RF signals.

Any terminal software (such as Hyperterm, XCM, X-CTU, PuTTY, TeraTerm) can be used.  Simply connect it to COMx (where x is the COM port number).  By default, XRFs communicate at a baud rate of 9600, so set this in your terminal software.  If you've programmed your XRFs to use any other baud rate, change your terminal software accordingly.

 

FTDI Connector

There are two strips of pads for physical serial connection to program devices directly.  Connect a 5 pin male header to the 5 pins at the end of the URF to allow you to connect directly to a Xino device.  Connect a 6 pin female header to the 6 pins nearest the USB plug to allow you to connect directly to an Arduino FTDI, OpenKontrol Gateway or Nanode (and probably anything else with a 6 port FTDI plug).

 

 

In order to swap between the RF wireless transmissions and the wired FTDI/Xino connection you will need to connect a couple of pins with a jumper where indicated by 'RF/Wired' in the photo above.  Note that the URF must be disconnected from the PC when swapping between RF and Wired modes.
