How do I update WebDAQ firmware?

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 your device.
    Firmware Panel Firnmware Updates page
  3. Tap Check for updates. The Measurement Computing Firmware Updates page opens.
    If newer firmware is available for the WebDAQ than what is installed, download the update file to your computer or to the root directory of a USB device or SD card.
    If you downloaded the update file onto external media, insert the media into the WebDAQ device and go to step 4. If you downloaded the update file onto your computer, upload the file onto the WebDAQ: open the Data Files window, Files tab and select the location to upload the file (Internal Storage, SD Card, or USB Storage Device). Tap file_upload Upload, select the update file, and choose Open.
  4. 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 a firmware 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.

Why did I get a 'File too large' error?

Internal WebDAQ storage can hold up to 3 GB of data. When acquiring larger data files, use external media. If you expect to acquire a large amount of data to a single file when logging to external media, do not use media formatted with the FAT32 file system as the max file size is limited to 4 GB. If the log file on FAT32 media grows beyond that size, a "File too large" error is returned and the acquisition stops. Before starting a logging session of this type, reformat the media using a different file system such as NTFS.

USB drives and SD cards are available formatted with different file systems. WebDAQ supports FAT32, exFAT, ext2/3/4, NTFS file systems. Refer to the table below for key differences between these file systems.

File SystemMaximum File Size
FAT324 GB
exFAT16 EB
NTFS16 TB
ext2/ext316 GB to 2 TB
ext416 GB to 16 TB

Use the file system that best suits your needs.
