The USB Console Adapter was designed to overcome the lack of a dedicated RS-232 console port on newer network devices. It is typically installed between the Local Manager and a network device, providing an RS-232 RJ-45 interface on one side and a USB interface on the other. Installation and operation are simple, requiring only two connections plus power.

LED Status Lights

  • GREEN - device is powered
  • RED - booting or error
  • BLUE - device plugged in and active (normal operating state)

Test the connection

Once you have a BLUE light on the USB Console Adapter, you should be able to test serial communication from the Local Manager. Log into the Local Manager, navigate to the appropriate port, and use the terminal command to verify connectivity.

If you cannot communicate with the device, check all connections and ensure baud rate settings are correct. If you continue to encounter issues, please contact Lantronix Support.

Setting the BAUD rates

The USB Console Adapter uses 9600 as a default baud rate. These can be changed using the following methods:

6.3.2 or later:

A menu option has been added to access the configuration of the Adapter by running ~o.

6.3.1 or earlier:

Earlier versions require us to access the Adapter manually to make changes.

  1. Remove the end device if it is already connected
  2. Change the baud rate of the Local Manager port to 9600 by running configure serial.
  3. Access the Adapter console connection using the terminal command.
  4. Run the command BAUD <required baud rate> (e.g. BAUD 115200)
  5. Run the command USBBAUD <required baud rate> (e.g. USBBAUD 115200)
  6. Exit the console using the ~[ENTER] command and reset the port baud rate using configure serial

Setup complete

The USB Console Adapter does not require any further configuration. If power is lost, the connection will drop. Communication will resume when power is restored.
