communication between xbee and picdem z

I am trying to communicate Picdem z modules with Xbee series 2 coordinator.
Even after configuring Pic to work on the same channel, pan id as the xbee , Xbee doesnt communicate with my PICmodules.
What are the configuration need to be done in xbee?
There is a extra 64 bit address header in the Xbee packet?What is the way of getting rid of it?
