SELECTION
If necessary modify the Serial Port (COM) associated with the N120
select the "USB Serial Port (COM X)" where is connected the N120.
Go to "Action / Properties" and in the "Port Settings" then click
"Advanced ..." tab, as Fig. 10a and Fig. 10b. If this tab does not
appear, the driver was not installed properly and you should reinstall
the software DigiConfig. In the "Advanced Settings for COMx"
window change the "COM Port Number" parameter to the desired
COM number, as shown in Fig. 11. Some serial ports can be marked
as being in use (In Use). Just select one of these ports if you are sure
that it is not being used by any other peripheral of your computer.
In some situations the serial ports can be marked as in use even
when the associated device is not installed on your computer. In this
case it is safe to connect this port to the N120.

the "Advanced Settings for COMx" as Fig. 10a and Fig. 10b window.
As shown in Fig 11, the "Latency Timer (ms)" parameter must be set
to value 4.
