When trying to upgrade the firmware of the instrument, I receive the following error: “Cannot establish connection: Connection timed out”. But I have entered the correct IP address of the instrument and I can ping the instrument. What could be wrong?

Make sure that the instrument is in upgrade mode. On the instrument itself, navigate to Config -> Utilities -> System Upgrade -> Network Upgrade and select “continue” by pushing the ”SEL” button. Now the upgrade program will be able to interface with the instrument and commence upgrade procedure.
