Xbee 2.5 I/O passing


I'm very new to xbee and arduino development. Most of the guides for I/O passing with xbee seem to use series 1.

From what I've read on this forum and others it is possible to use series 2.5 for I/O passing however i can't seem to get it working!

I have one photodiode connected to a xbee usb explorer - D4 with ADC set in x-ctu (note:- ZNET 2.5 ROUTER/END DEVICE AT)

And on the receiving end I have a xbee 2.5 connected to a DFROBOT xbee arduino sheild. With the COORDINATOR AT firmware, setting D4 to ADC.

I have removed the atmega chip and using the board as a serial interface as i would expect to see something in the terminal when the value changes on the transmitter (Please correct me if i'm wrong).

On the receiving end I want to display the light level from the transmitter using a LCD(this shouldn't be an issue)

Could someone tell me what x-ctu settings to use on the transmitter and the receiver? Do I need to use the API firmware on the coordinator?

Any help/hints/tips would be great.

Thanks Daniel
