Official Troubleshooting Steps
Cause: An error occurred trying to log in as an iPendant connection. Remedy: If you are using Internet Explorer, verify the settings. The PC must have Microsoft™ Internet Explorer 5.5 or greater installed. The PC must have the iPendant Controls installed. The PC must be connected to a network, and be properly configured to allow a TCP/IP connection to and from the robot controller.
