Drag the modules you want near the base/output module to add them to your switch configuration.
You can also move a module inside the switch using drag and drop.
To remove a module from the switch, drag it to the area below the switch (Drag here to remove from switch.)
There can be only one HDMI switch module per base unit and it must be in the first slot.
Once the module is in the switch, you can rename it with a double-click.
