I have two XBee’s set up on two different computers I ran the test query and they both came up fine. Both of them are set to the same chanel same baud rate and same Pan ID. When I run the range test on both PC’s at the same time I get a “timeout waiting for data” error. How do I do the range test? I have tried so many things.

Try following the steps described in the XCTU users Guide located at [http://ftp1.digi.com/support/documentation/90001003\_A.pdf](http://ftp1.digi.com/support/documentation/90001003_A.pdf)

Apparently the API setting in the modem configuration tab must be DISABLED for the range test to properly work. I used two computers and two Xbee modules to get the test to work properly.
