Hi Atsushi,
there is a way to retrieve the data from the EVM without using the GUI.
Conenct the EVM to the PC.
Open a telnet connection (such as using Termite) to the EVM (the EV M is recognized as a virtual COM).
Once the communication is estabilished, type "?" (question mark), a menu with all possible selections will appear.
From the menu you can retrive single data on demand or streaming data.
regards,
Domenico
