Thanks jezuz,zigbe31416 
i have downloaded X-CTU and test configuration of my xbee
modems , it replies me XB24,firmware version=10E6.
And read all parameters ,which are default parameters.
Both XBEE modem are configured as channel C(having same channel)
and ATID is 3332(network ID)which is again same for both.
My QUE is , should i change MY and Destination parameters(DH &DL)
in order to make communication in between two.
OR it will work with default setting.
Thanks in advance
