Check cables
Double-check all cables. The USB cable should be firmly and fully attached to both the computer and
the XBee development board. When attached correctly, the association LED on the adapter will be lit.
Check that the XBee module is fully seated in the XBee
development board
When the XBee module is correctly installed, it should be pushed fully into the board and no air or
metal should be visible between the plastic of the adapter socket and the XBee module headers. Also,
double-check that all ten pins on each side of the XBee module made it into a matching hole in the
socket.
Check the XBee module orientation
The angled "nose" of the XBee module should match the lines on the silk screening of the board and
point away from the USB socket on the XBee development board.
Check driver installation
Drivers are installed the first time the XBee development board is plugged in. If this process is not
complete or has failed, try the following steps:
1. Remove and re-insert the board into your computer. This may cause driver installation to re-
occur.
2. Remove and re-insert the board into another USB port.
3. (Windows) Open Computer management, find the failing device in the Device Manager section
and remove it.
4. Download the appropriate driver. You can download drivers for all major operating systems
from FTDI for manual installation.
Check if the modules are sleeping
The On/Sleep LED of the XBee development board indicates if the XBee module is awake (LED on) or
asleep (LED off). When an XBee module is sleeping, XCTU cannot discover it, so press the
Commissioning button to wake it up for 30 seconds.
