1-Way Wireless RF Touchpanel Crestron ST-1700C
Programming with VisionTools ™ 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 and 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 Downloads | Software Updates
section of the Crestron website (

Virtual Feedback
Programming a one-way RF touchpanel such as the ST-1700C 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 Application Builder takes care of all of this for you, as did its predecessor, the
SmarTouch Pro Editor. However, if you are programming your panels with SIMPL
Windows and VT Pro-e, you must follow the procedure described below 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.
Button press feedback produces a change in appearance from the inactive state to the
active state, or vice versa, as defined in the program.
• Momentary feedback, from inactive to active and back to inactive, has a short
duration, lasting only as long as the button is pressed.
• Toggle feedback produces a change of state each time the button is pressed.
• With Interlock feedback, only one button in an assigned interlock group can be
active at a time. Pressing an inactive button changes its state to active, and forces
the other buttons in the group to inactive. (To clear all buttons in the interlock
group requires that an extra button be added whose sole purpose is to force all the
others to the inactive state.)
• Duration feedback is assigned to a button that is to be activated and remain active
for a specified period of time, and then return to the inactive state.
In the following paragraphs, each feedback type will be discussed in detail as
applicable.
VT Pro-e Procedures
Buttons requiring feedback need to have the feedback type assigned as if it were a
property of the object. Button feedback logic is classified as momentary, toggle,
interlock, or duration. Logic is added to the buttons on the panel (after join numbers
and other properties have been assigned), by right-clicking the button in VT Pro-e and
selecting Feedback, which displays the “Feedback” window.
