thank you sir…i hv 1 another que that how to configure the xbee to api mode?

please tell me all the process in the detail…and

should all the routers and co-ordinator configure in the api mode for handelling the multiple routers using single co-ordinator?

No you do not need all of the nodes to be in API mode. really a router will automatically forward data on til it reaches the intended recipient node.
