Don't see parameters MY or CH

Hi. I’ve got a XBee Pro 900. All the tutorials I’ve seen say that the MY and CH parameters must be set for two Xbee’s to communicate in the simplest setup. Yet XCTU doesn’t show either of those parameters available to be set. How can this be?

Thanks!

The MY parameter is a 16 bit field. Most XBee modules use 64 bit addressing which uses the SL/SH as the source address and DL/DH as the destination address.
