Programming with VT Pro-e

VT Pro-e permits the creation of control screen variations incorporating two and
three-dimensional graphics and text. A set of pages, which make up a project, can be
designed for each CNX-DVP4 touch-sensitive screen overlay application. Each page
contains objects such as custom control graphics, video windows, two and three-
dimensional buttons, sliders, and digital readouts which allow the user to interface
with the control system. The project is uploaded into the CNX-DVP4's compact
flash. The unit uses the programmed project until another project is uploaded from a
PC. VT Pro-e also allows users the option to generate projects destined for web
browsers rather than for touch-sensitive screen overlays.
Configuring Video Windows
Video windows created on a page can be configured using the Video Properties
option. Once a video window is created using the Draw RGB
options, double-click the video window to open "Video Properties" so you can
configure the window. For additional software information, consult the VT Pro-e
help file.
"Video Properties" window description
Joins – allows the user to select different video sources, transition
durations, and transition effects and directions, using analog joins to be
displayed on one video window (overrides the set defaults in VT Pro-e).
Defaults – allows the user to assign the video source, transition or timing to
be used when a page flip, digital logic join or sub page is activated. The
selection can be overwritten with analog joins (refer to "Joins" above).
Select Properties – allows the user to select the size and position of a video
window, digital feedback joins (used for diagnostics), and allows the user to
enter a project description in the Description field.

Selecting a Video Source

There are two principle ways of selecting a video source.
1. Page flips or sub-pages with video objects on the page.
