Update the firmware using the CLI

If you have physical access to Connect Tank, you can use the CLI to update the firmware.

  1. Get the current Connect Sensor firmware.
    1. Navigate to the Connect Sensor firmware section of the support page.
    2. Click the link for the desired firmware option: Digi Connect Sensor Standard Firmware or Digi Connect Sensor Continuous Monitoring Firmware. For more information about these options, see Firmware options.
    3. Click download to download the firmware onto your hard drive. Make a note of the location.

  2. Open the enclosure and make sure the battery is connected and the SIM card is installed. See Step 3: Assemble Connect Tank.

  3. Connect a USB type A to B cable from your computer to the USB type B port.

Note Do not use the mini USB port, which is covered by a red X in the graphic below.

  1. You may need to install device drivers or wait for your computer to automatically install them when connecting Connect Tank to a computer using a USB cable. Digi recommends drivers available at www.ftdichip.com/Drivers/VCP.htm.

    Open a terminal program on a computer and connect to Connect Tank using the following configuration:
    • Connection port: Connect to the COM port associated with the USB cable connected to Connect Tank
    • Baud rate or bits per second: 115200
    • Data: 8 bit
    • Parity: None
    • Stop: 1 bit
    • Flow control: None
  1. Press the Wake button in the opened Connect Sensor+. A command prompt appears in the terminal program window.
  2. In the terminal program:
    1. Type fwupdate at the command prompt and select the YMODEM protocol to send the firmware file to the device. Refer to your terminal program documentation for how to use the YMODEM protocol.
    2. Press Enter. The device remains awake to load and install the firmware update. After the device completes the change, it sends its updated status information to Remote Manager.
  3. Press the Wake button and type status at the command prompt to verify the firmware version.
  4. When the process is complete, close the cover on the device. The cover snaps into place.

    Note The Connect Sensor+ enclosure may require some force to close. This is intended as part of the design to ensure a robust seal in damp or dusty environments. For details about closing the Connect Sensor+ enclosure, see Closing the v2.
