You may require access to Roos Instrument's Guru located in Santa Clara at "guru.roos.com". This connection facilitates RITS reporting, hardware upgrade support, test plan development, and other software upgrade and support issues. Typically, the production floor does not have direct outgoing connections to the internet, so some network configuration changes are required. Normally these ports are only necessary from a developer's workstation or Cassini system while they are actively working with RI a support issue. Users can push diagnostic data or configurations to RI or pull software updates to their local machine for evaluation. When the problem is solved, the updates can be pushed to the Guru server and automatically update all connected clients. Software updates occur when the Application is launched or configuration reloaded.
