how do you set an xbee to send a DI state change out its own uart

I have a two xbee network with one of the xbees plugged into rs232 to xctu. The xbee NOT plugged to the xctu WILL show a DI state change on XCTU. I cannot get the xbee plugged into the Xctu to show a state change. Please give guidance.

The local radio is not suppose to show a change of state out of its UART.
