Changing pages on the C2N-DVP4DI does not cause an effect to happen
unless a source also changes.
•
The C2N-DVP4DI does not support JNR (join Number Remapping).
•
The C2N-DVP4DI does not receive Serial Broadcast from indirect text
broadcast signal.
When creating a new VT Pro-e project for the C2N-DVP4DI select the C2N-
DVP4DI as the panel type. Go to Edit | Project Properties and select the Design
tab. Set the Panel size (horizontal/vertical pixels) to the native resolution of your
display device. Do this first before creating any pages. The output resolution of the
C2N-DVP4DI must match the native resolution of your display device, and the VT
Pro-e project must match the output resolution of the C2N-DVP4DI. If these
resolutions do not match, the video windows will not function properly.
To have the C2N-DVP4DI change an on-screen video source, create pages in VT
Pro-e containing a video window, and assign the video properties for the source,
size, transition and duration of the effect using the input select and default effect area
in the video properties window. When you want another video source to replace the
previous video source, page flip to the new page that has the required source. Page
flips can be generated from another panel or from a button press on the C2N-
DVP4DI. There are other ways to change the source on the screen and are described
later in the manual. There is an example VT Pro-e project for the C2N-DVP4DI on
page 49.
VT Pro-e Programming Notes for C2N-DVP4DI
•
Default transition effects will not occur if a value has been entered in analog
value, or if the sources are on-screen and are changing size and/or position.
•
The analog value transition overrides the default transition effect. You
must zero out (0) the analog value to allow the default transition to take
effect.
•
If you do a page flip or sub-page to another page that has the same sources,
and they are the same size and/or position, the C2N-DVP4DI will not
change or disturb that source even if you programmed a different transition
or duration on that page or sub-page. This is an important difference
between the C2N-DVP4DI and a TPS touchpanel.
•
If the page flip or sub-page has a new source, it transitions the new source
on but makes no change to the existing sources if they are to remain on
screen.
•
If only the size and/or position are changed on the video source window, the
C2N-DVP4DI will not perform the programmed default transition effect. It
will either perform the stretch effect or a fade off / fade on to the new size
and/or position, depending on the source. Refer to "RGB and Video
Options" in the C2N-DVP4DI Operations Guide (Doc. 6112) for more
information.
•
The vertical frequency for RGB sources must be the same as the C2N-
DVP4DI output vertical frequency to perform the stretch effect. If the
vertical frequencies do not match, the C2N-DVP4DI defaults to the fade
down / fade up effect, overriding the SETUP | OPTION setting. Video
sources are scaled to the C2N-DVP4DI output resolution and frequency to
allow the stretch effect to work.
•
Changing an analog join transition or an analog join duration does not take
effect on the screen until a source change occurs. It does not drive the
current source to redraw with this new effect.
