4. Select digital output port B by clicking Port B .
5. Click the appropriate bits to select the type of signal to write from the digital output lines.

not selected, a low-level signal is output from the digital output line. Optionally, you can
enter an output value in the Hex text box.
6. Click Send .
The application outputs and displays the value of each digital output line of digital port B on the
screen in both text and graphical form.
