problem in communicating

i configured my xbee module part number XB24CZ7PIT-004 exactly the way i configured XB24CZ7WIT-004. But still i am not able to communicate. Whereas i can communicate through XB24CZ7WIT-004. i would appreciate some help in this matter on a private forum.

Are you saying that module2 (XB24CZ7WIT-004) can talk to module1 (XB24CZ7PIT-004) but opposite is not true?

If so, then check if addressing has been done properly on module1 i.e. its DH and DL parameters are pointing to correct address.
