RobotStudio event

Error 41820: Invalid EGM identity

I am planning to set up a communication end point using Visual Studio to control Yumi robot. I have just configured Udpuc device in ABB robot studio but it keeps giving me the same problem (Error 41820: Invalid EGM identity). I am not sure whether it is due wrong IP address or name. What is the IP address that I should put? According to the maual it says 'IP address of the remote device', not sure what it means.. Is it the IPv4 address of my computer?  What should be the name of the UdpUc device? Please help... Thank you!
