B) MSView now needs to know to which COM port the SunSaver MPPT is connected. Use
the dropdown list to select the appropriate COM port. Note: If using a direct serial connec-

port may be something very different. You can verify the COM port number when using a
USB/Serial adapter by going to the Windows Device Manager.
