Configuration by the Telnet Console‎

The device can be also configured via the Telnet Console. Firstly, make sure that converter is connected to the power supply and to the LAN using a patch cord. Knowledge of the device’s IP address (default is 192.168.100.100) and Telnet port number (default is 23) is necessary to establish a connection.

Use command below in a terminal window to connect to the device:

telnet <ip_address> <port_number>

If the connection is successful there will be a login prompt visible. Log in using user’s personal credentials or the default login details (login: admin, password: admin123). If login is successful, it will be possible to start typing configuration commands.

The configuration is available only if devices are connected to the same Local Area Network as the computer used for it.

    List of uarts services status.
    
    Example:
    uart_service list
    1 state: ON service: Remote COM port: 1504 enc: YES
    2 state: OFF service: TCP Socket port: 1510
    3 state: OFF service: UDP Socket port: 1510
  - uart_service UART_NUMBER state STATE
    Set UART_NUMBER state to STATE. STATE value can be only ON or OFF.
    
    Example:
    uart_service 1 state ON
  - uart_service UART_NUMBER service SERVICE
    Set UART_NUMBER service to SERVICE. SERVICE value can be one of the following: Remote COM, TCP Socket, UDP Socket.
    
    Example:
    uart_service 1 service TCP Socket
  - uart_service UART_NUMBER port PORT_NUMBER
    Set UART_NUMBER port to PORT_NUMBER. PORT_NUMBER value can be any in the range: 1-65535.
    
    Example:
    uart_service 1 port 1501
  - uart_service UART_NUMBER enc ENC_STATE
    Set UART_NUMBER encryption to ENC_STATE. ENC_STATE can be only YES or NO.
    
    Example:
    uart_service 1 enc YES
    
    If ENC_STATE is YES then it will ask for a new password for encryption.

Network settings

The following commands might be helpful to change network settings according to target LAN parameters.

Additional notes

After some time of inactivity, session will be disconnected automatically.

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

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

Factory reset is not available from the Telnet Console level.
