Use the Device panel to view information about WebDAQ hardware, the capacity of internal and external storage, network settings, security access, and email settings. The Device Info tab displays by default when you open the Device panel.

Device Info tab

Each panel can be minimized by the user.

Device Info

The Device Info tab lists information about the WebDAQ device, system clock, firmware version and update utility, and calibration status, and provides two log files — the Info Log File lists notifications such as start and stop times, and the Error Log File lists error notifications.

Device Info Tab
DeviceInformation about WebDAQ hardware:
  • Name: The name assigned to the WebDAQ hardware. You can accept the default value or enter a new name. The name is saved in EEPROM, written to a hostname file at device boot up, and included in the data file header.
    When entering a new name, all alpha-numeric characters are valid. The name can't begin or end with a hyphen, nor include special characters.
  • Model: The model name of the WebDAQ hardware.
  • Serial Number: The serial number assigned to the WebDAQ hardware.
  • Mac Address: The Mac address assigned to the WebDAQ hardware. This address is also on a label on the enclosure bottom.
  • Restart: Sends a reboot command to restart the WebDAQ hardware. If an unexpected system error occurs during an acquisition, Safe Mode can be enabled using the "Restart in Safe Mode" checkbox in the confirmation dialog to prevent a schedule from starting automatically on power up.
  • Shut Down: Sends a shutdown command to the WebDAQ hardware. This option is disabled when Power Button Action is set to Restart on the User Preferences window. (This is the appropriate setting when jumper W1 is removed.) Note that when jumper W1 is removed, the only way to shut down the WebDAQ is to unplug the power adapter. Refer to the Power-On Mode topic for more information about this mode.
System ClockThe clock settings set on the WebDAQ hardware. These clock settings may be different from that of the user accessing the hardware. Tap the "Change date and time settings" link to show a Date and Time dialog with additional options:
  • Timezone: Select a timezone from the drop-down list.
  • Synchronize with Internet Time Server: Tap on to synchronize the system clock with the National Institute of Standards and Technology (NIST) server. Tap off to manually set the date and time. This setting is on by default.
  • Date: Enabled when Synchronize with Internet Time Server is off. Use the selector controls to select a date and time, or enter the time directly in the fields provided.
Tap Apply to close the dialog box and save the settings.
FirmwareInformation about device firmware.
  • Version: The firmware version installed on the device.
  • Check for Updates: Opens the Firmware Updates page at Firmware Updates.
  • Update button: Searches the root folder of each storage location on the device for a firmware update file. When a file is detected, the update automatically installs and the device is restarted. To avoid confusion, we recommend that only one firmware file be present on each storage location at any time.
    Refer to the Firmware Update procedure for detailed information.
CalibrationCalibration information:
  • Cal Date: The date when the WebDAQ hardware was last calibrated.
  • Cal Cycle: The recommended calibration interval. The default is 1 year. Return the WebDAQ hardware to the factory for recalibration. Field calibration is not supported.
Bootloader Information about the device bootloader.
  • Version: The bootloader version installed on the device.
  • Check for Updates: Opens the Firmware Updates page at Firmware Updates.
    Important! Updating the device bootloader is not typically required. Perform a bootloader update only if there are specific instructions on the Firmware Updates page to do so.
  • Update button: Searches the root folder of each storage location on the device for a firmware update file. If an *.swu file with a bootloader version later than that installed on the device is detected, the bootloader automatically installs, and the device is restarted.
Log FilesContains the Info and Error log files and a toolbar.
The Info log file lists device startup initialization information, job and schedule activity, and alarm activities since system startup. The Error log file lists all errors that have occurred since system startup.
Log Files Toolbar:
  • Refresh: Refreshes the log file.
  • do_not_disturbClear: Removes all notifications from the log file.
  • file_downloadDownload: Downloads the info.log or error.log file to the local drive location determined by your browser download settings.
  • Auto Scroll button: Scrolls to the end of the log file.

The Storage panel lists the amount of used and available storage space on the device and external media, if present. Partitioned storage areas are indicated with "P#".

Storage tab

An Eject button appears on the panel for external media. Use this button to unmount the media for removal. Note: if the external media is actively being used for data logging, this button will do nothing when clicked.

Storage Tab
Internal StorageAlways shown. Shows used and free space on the integrated internal storage of the WebDAQ.
SD CardShows only if an SD Card is mounted on the WebDAQ. Shows used and free space on the external storage of media inserted in the SD slot of the WebDAQ. An Eject button is shown that can be used for safe removal of the media.
USB Storage DeviceShows only if a USB mass storage device is mounted on the WebDAQ. Shows used and free space on the external storage of media inserted in the USB connector of the WebDAQ. An Eject button is shown that can be used for safe removal of the media.

The Network tab lists network configuration settings and status, and allows selection of WiFi interface if a WiFi adapter is installed in one of the WebDAQ USB ports. Note — a wired connection must first be established before a wireless connection can be configured

Network tab

The WebDAQ IP address type is set by default for DHCP/Link-Local. When connected to a network, the device first attempts to receive an IP address from a DHCP server. If this fails, the link-local address stored on the device is used (
