RFBee with Arduino FIO and XBee Explorer USB Dongle

Hello. I`m a newbe to Arduino and try to setup an wireless Sensor with RFBee communication.

As the title say, I`m trying to use RFBee-Moduls with an Arduino FIO Board and an XBee Explorer USB Dongle to program the Modules.

I tryed the FioXBee Congif Tool, X-CTU, Terminals but nothing could get me to the RFBee.
The Terminal could connect to the USB-Port, but can´t send commands to the RFBee. The TX LED of the Dongle lights up when I send a command, but no response of the RFBee.
The FioXBeeConfigTool can´t enter the command mode und X-CTU thows out an error window which tells me to reset the xbee.

I don´t know if all the tutorial I read just work on XBee-Moduls ore if they also compatible to RFBee.
