XBee transceiver

I am hooking up a mega 2560 to a sht15 temp/humidity sensor. It is working fine. Now I need to make it work over a XBee network. Problem is I need some help identifying the receiver. The transmitter on the 2560 is mounted on a ArduinoXBee v1.1 shield. http://img685.imageshack.us/i/imag0311o.jpg/ http://img192.imageshack.us/i/imag0312.jpg/

Can anyone tell me what the model of that is by chance? Obviously its a Maxstream (now digi) but I can't seem to match a model to get the drivers for this. Thanks in advance.

Help me understand. The picture is of an XBee mounted to what appears to be a digi development board. To get the model number, unplug the XBee, turn it over and read the number printed on the shield over the transmitter. Next, what do you mean by drivers? An XBee attached to an arduino doesn't use drivers, you get a library or you write code to make it work.

I'm having a little trouble understanding.

Sorry...too little sleep made my terminology completely wrong. The maxstream board's usb driver was corrupt and once I found and updated it then the communication worked.
