Device firmware is bundled with the operating system, web server, and documentation in a software update (*.swu) file. Use the Firmware panel on the Device window Device Info tab to download and install device firmware.

1. Open Device and locate the Firmware panel.
2. Note the firmware version installed on the WebDAQ.
   
3. Tap Check for updates. The Firmware Updates page opens.
   If newer firmware is available for the WebDAQ than what is installed, download the update file to the computer or to the root directory of a USB device or SD card.
4. Tap Check for updates to contact us for firmware updates.
   If newer firmware is available for the WebDAQ than what is installed, a link will be provided to download the update file to the computer or to the root directory of a USB device or SD card.
• If you downloaded the update file onto your computer, upload the file directly to the WebDAQ using the Data Files window Files tab: select the location to upload the file (Internal Storage, SD Card, or USB Storage Device), tap file_upload Upload, navigate to the update file, and choose Open. The update file is uploaded to the specified location.
• If you downloaded the update file onto external media, insert the media into the WebDAQ and go to step 4.
  Note that this method is also used to update firmware when a network connection is not available; refer to the procedure below.
5. Tap the Update button on the Firmware panel.
   The software waits 10 seconds before searching for the update file to allow for slower devices to enumerate, or to insert removable media containing the update file. After 10 seconds WebDAQ searches the root folder of each storage location for the update file. When a file is detected, the update is automatically installed and the WebDAQ Series hardware is restarted.
• The time on the System Clock panel stops as the update is installed, and restarts when the update is complete. Refer to the hardware manual for your WebDAQ Series device for the LED behavior during the update process.
• To avoid confusion, we recommend that only one WebDAQ firmware file (*.swu) be present on internal device storage or external media at any time.

After the update process is complete, refresh your browser window and verify the version on the Firmware panel.

When the software update file is copied to WebDAQ internal storage, it is automatically deleted after the update procedure is completed.

The web page will be unable to automatically connect to the WebDAQ after the update if you connect to the WebDAQ using mDNS (User-name.local) and have set the device name to a custom value. In this case connect to the device using the default name http://webdaq-xxxxxx.local, where xxxxxx is the last 6 digits of the MAC address, and then change the name back to a custom value, if desired.

Updating WebDAQ firmware when a network connection is not available

Use removable media to update WebDAQ firmware when a network connection is not available. This method requires that users download or copy the .swu file to the root directory of a USB device or SD card when a network connection is available. To avoid confusion, we recommend that only one WebDAQ firmware file (*.swu) be present on external media at any time.

1. Press the Power button to shut down the WebDAQ.
2. Insert the removable media containing the .swu update file into the WebDAQ.
3. Press the rear panel FUNC and POWER buttons at the same time until the POWER LED blinks yellow.
   The WebDAQ powers up and searches the root folder of each external storage location for an update file.
4. When a file is detected, the update is automatically installed and the WebDAQ is restarted.

Refer to the WebDAQ hardware manual for more information about these buttons.

Updating the software using this method is the same as initiating a firmware update using the web interface.

Recovering from a failed update

If the update process is not successful, perform the following procedure to update the software image:

1. Press the Power button to power down the WebDAQ.
   If the device is not responsive, press the Power button for 4 seconds to force the device to power off; unsaved changes may be lost.
2. Press the rear panel FUNC and POWER buttons at the same time until the POWER LED blinks yellow.
   The WebDAQ powers up and searches the root folder of each storage location for an update file.
3. When the file is detected, the update is automatically installed and the WebDAQ is restarted.

Refer to the WebDAQ hardware manual for more information about these buttons.

Updating the software using this method is the same as initiating a firmware update using the web interface.
