How do I know what the IP address of the MC200 is?

I know I need to plug away at it.... I just get a little fed up with it sometimes and give up. I haven't even re calibrated my processor set up for the new room yet as a. I don't have a PC. b. Even when I did the connection to fetch the data was so temperamental and hardly worked. Again, I gave up with it....
