Properties.
•
To change the assigned COM number, go to the Start menu, click Control Panel then System. Select the Hardware tab and then Device Manager.
Select the category “Ports (COM & LPT)” and right click the device “USB-to-Serial (COM x)” (Or a similar name. “X” represents the assigned COM
number). Click the Port Settings tab, then the Advanced button. A box will be in the lower left corner to assign a different COM port to the adapter.
