Video driver for Vision

[bjorn1985]

Hello everyone,

I am currently trying to display an image on a Real-Time Desktop using Vision. To do this, I am using the RT Video Out with Overlay example. The VI appears to run, however there is no new image displayed on the monitor and when I stop te VI, Labview returns error

-174396016. It also states there is no video driver installed (IMAQ Vision 0xBFF60490).

How can I resolve this error?

Hi Bjorn1985

The IMAQ RT Video Out feature is available only on systems that feature the i815 chipset or the i845 chipset. The currently the following devices are supported by this function:

Device	Functionality
NI 8195, and NI 8196	Does Not Support RT Video Out
NI 8184, NI 8185, NI 8186, and NI 8187	Supports full functionality
NI 8175, and NI 8176	Supports full functionality
NI 8170, NI 8156B, and NI 8140 RT Series	Does Not Support RT Video Out

If you are using a PXI Controller that does support the RT Video Out functionality and you still can't see your images, you should try using the IMAQ Video Out Display Mode VI to configure the video mode before you attempt to display the images. This VI allows you to set the refresh frequency, screen area, and color depth. Note that if you are using a monitor that does not support high refresh frequencies, the images do not display correctly. Refer to the monitor documentation for information about supported refresh frequencies.

Hope this helps

Thanks

I've heard that NI is working on a driver for the (as yet) unsupported RT controllers.

Is this true, or just another urban myth?

If no video driver is forthcoming for the higher-end PXI controllers, what about a PXI video card? Sure, it would take up a slot in the chassis, but that would be a worthwhile sacrifice to get back to the video capabilities that we once enjoyed with the (now discontinued) 8187RT.

The Celeron-based controllers just don't have the horsepower for our application. And now that the 8187Rt is gone, that leaves us without any options.

Anyone have another suggestion...?

Cheers,
