Note: The FT232RL provides a maximum of 50mA on the 3.3V pin. The XBee ZNet modules
pull a max of 40mA, so you should be ok. However, if you are using the XBee Pro version, you
may need to use an external 3.3V supply.
Step 2: Power-up the XBee and prep the software
After double checking your connections, use the USB-miniB cable to plug the FT232 Breakout
into a USB port on your computer. Both LEDs connected to the XBee should light up and stay
on (assuming your XBee shipped as a Router/End Device and there is no Coordinator around to
connect to).
Download the X-CTU software from Digi and install it. The software can be downloaded from
http://www.digi.com/support/productdetl.jsp?pid=3261&osvid=57&tp=4&s=269
Step 3: Run X-CTU and connect to the XBee
Run the X-CTU
software. You should
see a screen like the one
to the right. Single-click
on the USB COM port
that the XBee is
connected to. If you’re
not sure, you can click
the “Test/Query” button
to read each COM port
to discover which one
has the XBee.
