Configuration by the Serial Console‎

RemoteCOM (C20 - C25)

Another way to configure the device is via a serial console. In case of the C20 - C22 Ethernet Converters an additional USB/UART converter is needed.

Procedure to enter serial console mode on C20 - C22

• Turn off the power of the device.
• Connect the PC to the C1 micro-USB port of Ethernet converter using the dedicated USB/UART converter.
• Open the serial console (default baud rate is 115200 bps).
• Press and hold the S1 button (or connect Din pin to GND pin if the button is not mounted).
• Turn on the power and wait a few seconds until the orange LED lights up.
• Release the button (or disconnect Din pin from GND pin).

Procedure to enter serial console mode on C23 - C25

• Install STM32 Virtual COM Port Driver.
• Turn off the power of the device.
• Connect the PC to the C1 micro-USB port using the USB cable (or use the dedicated USB/UART converter).
• Open the serial console (default baud rate is 115200 bps).
• Press and hold the S1 button.
• Turn on the power and wait a few seconds until the yellow CN LED lights up.
• Release the button (or disconnect Din pin from GND pin).

Service mode

Procedure to enter service mode for C20 - C22 converters

• Turn off the power of the device.
• Connect Ethernet converter to the dedicated USB/UART converter via the microUSB port.
• Connect the USB/UART converter to the PC.
• Open the serial console (default baud rate is 115200 bps).
• Press and hold the S1 button.
• Turn on the power.
• Wait until the ST indicator (red LED) lights up.
• Release the S1 button.
• If the process is successful, service commands can be typed into the terminal.

Procedure to enter service mode for C23 - C25 converters

• Install STM32 Virtual COM Port Driver (if it was not done before).
• Turn off the power of the device.
• Connect Ethernet converter directly to the PC (the dedicated USB/UART converter is not obligatory).
• Open the serial console (default baud rate is 115200 bps).
• Press and hold the S1 button.
• Turn on the power.
• Wait until the ST indicator (red LED) lights up.
• Release the S1 button.
• If the process is successful, service commands can be typed into the terminal.

List of commands in the service mode

In the service mode, the “ipconfig” command can only show a last static IP address.

Factory reset

To restore default settings, type “defaults”. After that, user will be asked to type “default network” to reset the network settings as well. Then user will be informed if the process is successful.

Additional notes

In order to avoid issues like connecting to host, type “help” to get more information.

To get more details about every particular command, append “help” after each commands (example: "ipconfig help").
