Getting started

  • Make sure that converter is connected to power supply and to the LAN using the patch cord

  • open the Telnet console

  • Create a new connection with the converter (converter’s IP address will be necessary)

  • Login using your personal credentials or default login details

  • If login is successful, you will be ready to start typing configuration commands

Configuration is available only if devices are connected to the same Local Area Network as the computer you are using.

Ports configuration commands

In terms of ports configuration it is possible to change parameters like: service, baudrate, data bits, parity, stop bits and so on. UART commands below.

    • 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_STAE. 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

If you need to change network settings according to target LAN parameters, the following commands might me helpful.

Changing username or password

To change username or password, use user command.

Available commands:

  • user help
    Print help
    Example: user help

  • user mod_name USER_NAME NEW_NAME

    It fails in case the name is used by another user
    Example: user mod_name admin john

Additional notes

After few time of inactivity, session will be disconnected automaticly.

In case 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).

Factory reset is not available from the level of Telnet console.
