\- MA Fixture and RDM Fixture have the same universe

1. Open the RDM devices window. Press Setup, and tap under **Show** at Patch & Fixture Schedule.\
   The **Edit Setup** opens.
2. Tap in the lower right corner at RDM devices.\
   The **RDM devices window** opens.
3. To select the fixture type you like to auto-patch, tap at the corresponding fixture type under **Discovered RDM FixtureTypes**.\
   The fixtures to the selected fixture type are displayed on the right side of the RDM devices window.
