Firmware update via the USB interface

Tutorial: Firmware update via the USB interface

The mbNET-device firmware can be uploaded using the USB-ínterface. To do this please follow the procedure below.

1. Preparation

2. Execution

1. Preparation

1. Go to https://downloadportal.mbconnectline.com/en/mbnet.html and download the latest firmware version (e.g "mbNET_FW_V712.zip").
2. After extracting it, you will find the actual firmware file ("image.bis" (HW01) or "image.swux" (HW02)) along with the "changelog.txt" and "open-source-software-licenses.txt” files.
3. Save the firmware image file on a USB stick.

Direct Upload of a Configuration After the Firmware Update (Optional)

To save steps, you can have a configuration loaded immediately after the firmware update. In addition to the image.swux firmware file, place a configuration file that you have renamed to mbconnect24.auto.

Start the firmware update as described and leave the USB stick plugged in. During the first reboot after a firmware update, the router will check for the presence of the mbconnect24.auto file and will load it if present. After about 5 minutes, the router will have the new firmware and the new configuration.

2. Execution

When the mbNET is ready for operation (LED Pwr + Rdy light up), connect the USB stick to the USB interface of the mbNET-device.

1. As soon as mbNET-device.detected and verified the firmware image file  LED fc1 + Fc3 start flashing.
2. Now press the Dial Out button and keep it pressed until LED Fc2 flashes.
3. Release the Dial Out button.
   The mbNET now performs a device reboot.
4. If both the Pwr and Rdy LEDs light up, the firmware update is complete.

Warning

IMPORTANT: During the firmware update
- do not push the Reset button
- do not turn off the power supply
- do not remove the USB drive while the update runs

The mbNET is now ready for operation and can be used again as usual.

Notice

- If both the firmware as well as a mbCONNECT24 portal configuration are on the USB stick, the firmware will always be detected by the mbNET (Fc1 + Fc3 flash). If you do not respond within 10 seconds, the Dial Out button switches the mbNET to Portal Configuration (Fc1 + Fc2 flash). If you do not respond within 10 seconds, the device will return to normal mode
- While we uploaded most common USB-drivers, sometimes a USB stick is not recognised by the mbNET-device. In this case please try a different USB stick.
