source address in xb24dm

How can i edit source address in xbee 24 digimesh modules?

Assuming you’re referring to the SH and SL parameters, you can’t alter them. They’re factory set and every XBee gets its own unique address.

the source address is the fixed ones and we cannot change the address as the manufacturer fixed it(just as u r name).
we generally dont have any problems with that address.what are the problems u r facing with them?

If you want you can set the Node Identifier (NI) to give each module a unique name.
