Xbee Serial Port Radio Link

Using AdaFruit Xbee carrier boards, you can add a Xbee radio link to the router. The radios I am using are rated for a maximum distance of 300 feet and cost around $20, however, you can upgrade the radios and there are some that go 1 mile, but cost twice as much. SparkFun electronics has a greater inventory of radios.

What you will need:

2 Xbee radios(http://www.adafruit.com/index.php?main_page=product_info&cPath=29&products_id=128)

2 Xbee carrier boards(http://www.adafruit.com/index.php?main_page=product_info&cPath=29&products_id=126)

1 USB FTDI cable(http://www.adafruit.com/index.php?main_page=product_info&cPath=29&products_id=70)

Female jumper wires(http://www.sparkfun.com/commerce/product_info.php?products_id=9389)

XCTU software to configure the radios(http://www.digi.com/support/productdetl.jsp?pid=3352&osvid=57&tp=5&s=316)

Make the Xbee Carrier Boards Again, visit the AdaFruit site and use her instructions for making the boards(http://www.ladyada.net/make/xbee/index.html).

Configuring the Radios The AdaFruit site has a link to configuring the radios which is excellent (http://www.humboldt.edu/~cm19/XBee%20setup.pdf). Read through the document and setup one radio as the coordinator and the other as the end device. You can also visit the Funnel site and grab their software to configure the radios(http://code.google.com/p/funnel/downloads/list). Download the XbeeConfigTool.zip. This software seems easier to use but has less option for configuring the radios.

Remember to set the baud rate to 115200, that is the baud rate of the router, and I am not sure if it can be changed. If somebody can tell me how to change the baud rate of the router, then by all means let me know!
