12 Firmware Upgrade Utility

The Firmware Upgrade Utility is used to upload new firmware files to a Levelogger. The zipped firmware file can be obtained from: www.solinst.com/downloads/


To check for firmware updates using Levelogger Software, retrieve settings from the connected datalogger (see Section 5)."Firmware Update Available" will appear in the top right menu bar if there is an update available. Clicking the message will open a webpage where you can download the firmware update. You can also use the Software's Help menu.

Make sure to unzip the firmware file after you have downloaded it, so you can access the *.ssf file.

To upload new firmware to a Levelogger, follow these steps:

  1. Open the Solinst Firmware Upgrade Utility from the Utilities menu in the main Levelogger Software. Pick the Com Port to which the Levelogger is connected and make sure the Baud Rate is set to 9600.
  2. Click the 'Open' button , which should open a file dialog asking for the firmware file (*.ssf) to upload. Navigate to the directory where the firmware file was saved on your PC, then click on the file and click 'Open'.
  3. Check the 'File Information' box to make sure that the opened file is the right one.
  4. Click the 'Upload Firmware' button , to start the firmware upload process.


    It is important that the communication between the PC and the Levelogger is not interrupted during a firmware/ calibration upload so please make sure to close any other running programs, including screen savers, and do not disconnect the Levelogger before the upload is finished.

  5. If a communication error occurs and is indicated in the 'Datalogger Status' section (Figure 12-1) either before the "Verified Program Checksum" message or after the "Program Information Section", then restart the upgrade process.
  6. If, however, a communication error occurs between the 'Verified Program Checksum' and the 'Program Information Section' messages, then please contact Solinst. You will need to give the Levelogger Serial Number and explain the exact positioning of the error message.

Solinst recommends using an Optical Reader to connect your Levelogger to the PC during a firmware upgrade to avoid any interruptions during the extended communication period.
