External Mode

Communication interface

Select the transport layer that the external mode uses to exchange data between the host computer and the target hardware.



Serial port

Specify the serial port that the target hardware uses.


Default: COM20

To find the serial port:

  1. Go to Start menu > Control Panel > Device Manager > Ports (COM & LPT).

  2. To expand the ports, that Windows recognizes, click the plus (+) sign. The port that you want is MBED Serial COM Port (COMx). x is the number of the port.

    For example, if the serial port is labeled as MBED Serial COM Port (COM1), in the Serial port parameter, specify the serial port as COM1.


Select this check box to view the external mode execution progress and updates in the Diagnostic Viewer or in the MATLAB® Command Window.
