    Please note the following:

    • Prior to updating the firmware, please read the corresponding release notes containing further update instructions. If the firmware version on your GSG unit is V4.05 or lower, several updates must be performed in the correct sequence.

    • In order for the instrument to communicate with the PC Software the NI VISA runtime software is required. The StudioView installation wizard will notify you, but if necessary, the NI VISA runtime software can also be downloaded directly from the National Instruments website:

    • Once a firmware upload is initiated from StudioView, any running scenario will be stopped, and the upgrade process status will be displayed instead. First, the progress of the file transfer is displayed. After the file transfer is complete, the actual upgrade operation is made. Finally, the GSG-5/6 unit will reboot with the new firmware installed.
    • The Windows Personal Computer onto which you will download the new firmware must have GSG StudioView installed on it, and must be connected to your GSG unit e.g., via Ethernet.
  4. Once you have prepared the firmware upgrade as outlined above, proceed to the topic Uploading StudioView Files.
