5.2. Manual Updates

Updating an offline instrument is accomplished with the following steps:

  1. Go to lakeshore.com and navigate to the M81-SSM downloads page. Click on M81-SSM Firmware Update under Software.

  2. On the Firmware Update page, click on the desired version number, which links to the .lsfw firmware update file.

  3. Copy or save the .lsfw file onto the root directory of a USB flash drive. Make sure it is the only .lsfw file in that location.

  4. Plug the flash drive into the USB-C port on the back of the instrument; if you don’t have a newer flash drive with a USB-C connection, use the adapter supplied with the instrument.

  5. On the M81-SSM front panel, tap the Settings menu (top left corner of the screen). Then tap System settings. Touch Update.

  6. Click “Updates are available. Click here to install,” and follow the on-screen instructions to update the firmware.

Note

Firmware comprises many files aggregated to form a Lake Shore firmware (.lsfw) package. The instrument stores versions of its .lsfw packages in its internal memory. This local memory location is called the “local repository.” This allows you to downgrade the firmware to older versions that remain on the instrument in the local repository.
