Connecting extra monitor to DVI-I connection EVS 1464 (displaying Front Panel)

Solved!
Go to solution

Hi,

 

Currently developing a Vision system using the following:

  • LabVIEW 2010 SP1
  • LabVIEW 2010 Real-Time SP1
  • Vision Development 2010 SP1
  • EVS 1464

 

My question is:

 

How can I display my front panel, running on the EVS, on a monitor connected to the DVI-I output of the EVS 1464?

 

Thanks ahead!

Hello,

 

Thanks for your posting in this forum.

Hi Roy, I'm not sure if Hossein actually read that KB or not, but it deals with displaying the front panel over the network on a Windows machine, not out through the monitor connection on the EVS running LabVIEW RT.

 

To answer your original question, no, it is not possible to view the standard LabVIEW front panel on the RT system today. All the code for displaying all the front panel UI buttons, controls, and indicators is simply not present in LabVIEW Real-Time and is only viewable on a seperate machine that is either running the development environment or using a web browser that has the LabVIEW plugin installed. 

 

Having a UI display on RT is certainly a requested feature and perhaps it might be available some day. You might want to check this request: http://forums.ni.com/t5/LabVIEW-Real-Time-Idea-Exchange/Real-time-display/idi-p/1391108 . It has some good ideas for what other alternatives exist today as well.

 

However, this is one way to use the monitor output on the EVS and other LabVIEW RT systems. Vision Development Module includes RT Video Out VIs that can display any image on the connected monitor. You can either display images captured from cameras or custom images, as well as overlay text and simple graphic objects (lines, circles, rectangles, etc). It is certainly more effort than the normal front-panel editor in LabVIEW but it might be suitable for your needs if you want a few things to display. Of course you will have no mouse/keyboard so you cannot interact with any on-screen elements directly.

Hi Eric,

 

Thanks for your info and useful explanation. You are right but I wanted to let him know what possibilities he has. That is why I posted that link. He could there find out that he cannot normally display the front panel in his RT system.

 

I hope that he have his answer now and thanks again for your input.

 

Regards,

Hossein
