4. Conguration
4.2. Connecting the USB cong adapter
For conguration and rmware updates we provide a special serial-USB adapter that can be
connected as shown in gure 4. The corresponding connector on the PCB is marked with
the word `Cong'.
The USB-adapter will add a virtual serial `COM' Port to your system. Your operating system
needs the CP210x USB to UART Bridge
driver installed. A download link is provided next
to the `Connect' button when you start the Maintenance Tool.
While the cong adapter is connected, the device will be powered from the USB port with
a regulated voltage of 3.3V. It is not necessary although it would be no problem hav-
ing batteries inserted or a dierent supply connected while using the cong adapter. All
conguration parameters will be kept non-volatile regardless of the power supply.

4.3. System parameters
After being successfully connected to the hardware using the Lobaro Maintenance Tool you
can press `Reload Cong' in the `Conguration' tab to read the current conguration from the
device. For every parameter a default value is stored non volatile inside the hardware to which
you can revert using the `Restore default' button in case anything got miss congured.
All LoRaWAN & other rmware parameters are explained in the following.
