7.6. Firmware Updates

Overview

The Model 346 can update its firmware manually by attaching a USB Type-C™ stick to the rear panel, or by downloading and installing updates from Lake Shore with a Model 346 source connected to the internet.

Model 346 firmware comprises many files, aggregated together to form a Lake Shore Firmware (LSFW) package. The Model 346 stores versions of its LSFW packages in its internal memory. This local memory location is called the “local repository”. This allows you to downgrade firmware should you choose, since older versions will still remain on the Model 346 in the local repository. In addition, Lake Shore maintains LSFW packages on a network server that allows us to deploy those packages to all Model 346 customers. This is called the “remote repository”.

Firmware update information can be found via the Model 346 front panel by tapping the Settings button, then tapping the Updates button. If a valid internet connection is present, the Model 346 will automatically check the remote repository for updates and display information about the latest available firmware.
