Configuration is easy thanks to Crestron's Windows-based programming software. Crestron SystemBuilderTM software creates a complete project, with no special programming required. SystemBuilder completes all necessary programming for a base system including all touchpanel screens and the control system program. The program output of SystemBuilder is a SIMPL Windows program with much of the functionality encapsulated in macros and templates. Once SystemBuilder creates the project, the system interfaces and program logic can be customized in SystemBuilder or can be easily modified with Crestron development tools (i. e. , SIMPL Windows and Crestron VisionTools® Pro-e (VT Pro-e) software packages). If a user wishes to create a touchpanel project using templates with a different look-and-feel, this can be accomplished by making a custom template.
