From time to time Vescent will issue new releases of firmware for the SLICE products. Below are instructions on upgrading the SLICE-QT firmware. Please follow these instructions carefully.

For SLICE-QT firmware versions 1.29 and lower, updating the firmware will reset all stored parameters (PID loop parameters, etc.). Before beginning a firmware update, manually record all settings for all channels. Versions 1.30 and higher will automatically store this information.

2. Copy the latest System Controller firmware update .dfu file from the ftp website (email sales [at] vescent [dot] com for latest firmware and GUI revisions) into the folder created in step 1.
   The file will be named SystemController-x-x.dfu where x-x will be the version number of the firmware.
   NOTE: This file may be renamed. However, the name must start with SystemController.
3. Copy the latest QT firmware update .hex file from the ftp website (see above) into the folder created in step 1.
   The file will be named 90-00001-upgrade-x-x.hex where x-x will be the version number of the firmware.
