MotionFire Dev Kit

Hello, I'm new here.

I need to connect this dev kit to PC via ethernet but i have a problem, i dont know the IP of FireFighter board, it should be static. To connect via RS232 i use RealTerm and everything seems to be OK, the documentation says that IP can be retrieve by UART-CH0 but i dont know how to get them. Could You help me ? Please and greeting :D
