NOT:N If communication still does not occur and you are using a DB9 to COM 1 or COM2, try using a USB to COM adapter.
This will usually create a new COM port that was not previously listed. Windows Device Manager can be helpful in
determining the actual COM ports that are available.
Figure 19: Device Manager
Select this new port created by the adapter and the screen should change as shown (Figure 20). Notice that the “---“
are replaced with values. This confirms normal communications.
