How to configure ip address/port with DDS Blockset

I have build the DDS application shapesdemo.exe with DDS Blockset. I have test the communication between shapesdemo.exe with OpenDDS Shapes Demo Application successfully. However, these two DDS Application run on the same desktop computer, I want to communicate shapesdemo.exe with another OpenDDS Shapes Demo Application runing on the different computer.

I want to configure the shapesdemo.exe with the another computer's ip address/port, such that it can communicate with another computer's DDS Application, where is the DDS Blockset ip address/port informations saved?
