Step 1. In this case you need to configure Address Mapping Set 1 from Menu 15.1 — Address Mapping

Step 2. Then enter 15 from the main menu.

Step 3. Enter 1 to configure the Address Mapping Sets.

Step 4. Enter 1 to begin configuring this new set. Enter a Set Name, choose the Edit Action and then enter 1 for the Select Rule field. Press [ENTER] to confirm.
