Programming with VT Pro-e

Control screen variations incorporating two- and three-dimensional graphics and text
are possible and can be created with VT Pro-e, a design/programming Windows
-based software program. A set of pages, which make up a project, can be designed
for each application. Each touchpanel can be organized with the ideal, color-oriented
control environment with custom control graphics: icons, two and three-dimensional
buttons, and floor plans. The project is uploaded to the touchpanel's flash PROM.
The touchpanel uses the project until another is uploaded from the PC. The PC may
be disconnected from the control processor except when uploading a project.
For additional software information, refer to the help file provided with the software.
The latest version of VT Pro-e can be obtained from the Crestron website.

Virtual Feedback

Programming a one-way RF touchpanel such as the ST-1550C requires consideration
of "feedback." Since the panels are one-way only, and there is no true feedback, you
must create "virtual feedback" so that buttons respond appropriately when pressed
and the user perceives no real difference between a one-way panel and a two-way
panel. The SystemBuilder takes care of all of this for you. However, if you are
programming your panels with SIMPL Windows and VT Pro-e, you must follow the
following procedure to add logic both to the touchpanel for button feedback and to
the control system program to properly process the signals, and to make sure that the
state of the buttons on the panel and in the control system remain in sync.
