Crestron Tutorial: Configuring the Hardware in a Crestron SIMPL Windows Control Program
Configuring your hardware is simple. In the Device Library on the left side pane, expand the Crestron Devices folder and then the Control Systems folder. Scroll down and highlight the CP2E processor.

Drag and drop the CP2E control processor (that you just highlighted) over the top/right pane labelled "Start by dropping a Control System here...". The symbol for the CP2E processor should appear in the System Views pane. (see image below)

You have now added your Crestron CP2E control processor to your project. Next, we have to add the CT-1550 touch panel to the project.
