On the main screen one can open the configuraiton of the controls with the icon :
In the example abouve there is already a configured control with the name "My Control".
At the bottom there is a button named "New" to add a new control to the configuration.
Usually there is only one control per modelrailway layout. For bigger layouts it can make sense to use more then one control, so there is a control for the locomotives, one for the accessories and one for feedbacks.
Acutally RailControl supports the following controls:
|ESU||ECoS/Central Station Reloaded|
|Märklin||Central Station 2/3 via TCP (new)|
|Märklin||Central Station 2/3 via UDP (old)|
