Host-board connection

Set host COM port

Automatically detect or manually set the COM port your host computer uses to communicate with the hardware board.

This parameter appears when the Hardware board parameter is set to LEGO MINDSTORMS NXT, Arduino Mega 2560, or Arduino Uno.

Warning

Do not connect Arduino® Uno and Arduino Mega 2560 to a RS-232 serial interface, commonly found on computers and equipment. RS-232 interfaces can use voltages greater than 5 Volts, which can damage your Arduino hardware.
