To calibrate motorized rotation stage, we need to set expert mode in quED, but don't know how. Tried to connect using HTTP interface using IP 169.254.48.242, but port 8080 only gives page with text "Request not understood.". Portscan also showed VNC (allows controlling controllers screen from computer) and SSH (don't know username and password).

Controlling motorized rotation stage from quED worked.
