how can I change or control ATMY in a Xbee series 2

hello everyone:
I was wondering how can I change or control My address in a Xbee series 2, this numbers are to big, and I don’t think my Javelin Micro-controller can handle those big numbers… or can I?


The XBee ZNet 2.5 modules (formerly XBS2) does not have a settable MY (source address) parameter. The reason is that, according to the ZigBee spec, the network assigns the address. Digi has though about this and given the modules an extra parameter just for this type of situation. The NI (Node Identifier) string allows you to give the module a unique 20 Byte ASCII name that you can use to address the module. For more detail look in the manual under the NI ND & DN parameters.
