When working with Adalm Pluto SDR devices, it is important to select the correct COM port for communication to ensure successful configuration and operation. Follow these steps to identify the correct COM port using the Device Manager in Windows:


Step-by-Step Instructions:

  1. Open Device Manager:
    • Press Win + X and select Device Manager from the menu.
    • Alternatively, you can type "Device Manager" in the Windows search bar and click on it.
  2. Access the Ports Section:
    • Scroll down and find the Ports (COM & LPT) section.
    • Expand the section by clicking on the arrow next to it to see the list of available COM ports.
  3. Identify the Correct COM Port for Adalm Pluto:
    • Connect Your Adalm Pluto SDR to the Computer using a USB cable.
    • Once connected, observe the Ports (COM & LPT) section in Device Manager.
    • A new entry named PlutoSDR Serial Console (COMX) (where X is the COM port number) should appear.
    • This newly added COM port is the one assigned to your Adalm Pluto device.
  4. Verify the COM Port:
    • Disconnect the Adalm Pluto SDR and see if the newly appeared COM port entry disappears.
    • Reconnect the device and ensure the same COM port reappears.
    • This process helps confirm which COM port is associated with your Adalm Pluto.
  5. Note the COM Port Number:
    • Make a note of the COM port number (e.g., COM6) for further configuration in your software.


Tips for Identifying the Correct COM Port:

  • Connect One Device at a Time: If you have multiple Adalm Pluto devices, connect them one by one to identify which COM port corresponds to each device.
  • Naming Conventions: The COM port entry will typically have "PlutoSDR" in its name, making it easier to identify.


Troubleshooting:

  • If you do not see a new COM port appearing when you connect your Adalm Pluto, ensure that:
    • The USB cable is securely connected.
    • The necessary drivers for Adalm Pluto are installed on your computer.
  • If multiple new ports appear, the correct one should have "PlutoSDR" in its name.


By following these steps, you can easily identify the correct COM port to use with your Adalm Pluto SDR, ensuring successful communication and configuration.
