the issue.
a. Check if the serial communications parameters were properly configured. In the GUI, click on the
“Options” menu, and select “Serial Port”. Verify if the port selected matches the MSP Application UART1
enumerated in the Device Manager, Windows system Control Panel. The baud rate must be set to
9600 (recommended). If no MSP COMxx ports were enumerated and displayed in the Windows Device
Manager, ensure proper power sequencing was followed. If necessary do a power off and on cycle. If
the following Windows Device Manager information is still not visible after the power cycle it points to a
hardware connection issue.
