Hi,
On the DNA server try… MD Support to change User Name & Password. Choose the menu… Synchronisation, Node Setup. Then you can select which node and set USER NAME and PASSWORD for the NIU.
Not 100% sure if TTY is a privilege but if it is… that would be set with User Configuration. Choose the user name, then select the application EMG, then the privilege TTY then click on the + (add icon).
Haven’t worked on DNA for a while so that’s a best guess...
