Host Interface Release 2 Release Notes

February 28, 2019

Introduction

These release notes describe how to apply this update, and the changes that have been made since the previous firmware release.

Applying this update will not alter the device setup, or clear log files stored on external media.

Applying This Update

Updates are applied using FTP, SFTP, or SCP. When using SFTP or SCP, connect to port 22, use "HCI" 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.

Perform the following steps to update your icListen:

1. Power the Host Interface using the supplied power adapter.
2. Connect to the Host Interface 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' Marco software.
   • Marco: Use the "Reset" button on the lower left area main display.
   • Web Interface: Type the IP address of your Host Interface into the address bar of your web browser (Firefox, Internet Explorer, etc), and use the "Reset" button on the "Power Operations" page to reset the instrument.
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, try refreshing the page in your browser.
