Introduction

These release notes describe the features present in this release, how to apply this update, what software is compatible with this update, and the changes that have been made since the previous icListen HF release.

Applying This Update

Updates are applied using FTP, SFTP, or SCP. When using SFTP or SCP, connect to port 22, use "icListen" as the user name, and by default there is no password.

While applying this update, take care not to interrupt the power to the instrument. Ensure that all necessary log files are retrieved from the instrument before applying this update, as they will be erased during the update process. Files may be retrieved using a web browser, or an FTP, SFTP, or SCP client (such as FileZilla).

Perform the following steps to update your icListen:

  1. Power the icListen using the power adapter (do not power from internal battery).
  2. Connect to the icListen via FTP, SFTP or SCP.
  3. Once connected, you should see a directory called "update". If this directory does not exist, create it. This directory name is case sensitive.
  4. Upload the update ".icu" file into the "update" directory.
  5. The instrument must now be reset in order for the update to take place. This can be done through the web interface, or using Ocean Sonics' Lucy.
  6. Allow approximately 5 minutes for the update to complete.
  7. The update should now be complete. You may connect using the web browser to ensure the update has successfully taken place. The "Firmware Release" number should be displayed on the "Home" page. If the release version is blank, or does not appear to be correct, press the "Refresh" button at the bottom of the page.
