Firmware update via the USB interface
You can update the mbNET directly via the USB interface. The device then automatically recognizes the
firmware saved to a connected USB stick. Pressing the Dial Out button starts the firmware update.
Preparation:
• Go to www.mbconnectline.com (downloads) and download the latest firmware version (e.g. "mb-
NET_FW_V624.zip").
• After extracting it, you will find the actual firmware file "image.swux" along with the "changelog.txt" and
"open-source software licenses.txt" files.
• Save the "image.swux" file on a USB stick.
IMPORTANT: The "image.swux" firmware file must not be renamed and must be stored in the top-level
directory of the USB stick! The USB stick must have the FAT file format!
Execution:
When the mbNET is ready for operation (LED Pwr + Rdy light up), connect the USB stick to one of the USB
ports of the device.
1. As soon as the firmware file has been detected by the mb-
NET,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.
The mbNET is now ready for operation and can be used again as usual.
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.
