Movimed AF-1501 series framegrabbers IMAQ/IMAQdx compatibility

[Alvin6688]

Hello NI Community,

I have been using AF-1501 framegrabbers with a cRIO for the past year or so, with no trouble, in conjunction with IMAQ drivers. Recently I installed the latest version of IMAQdx for another application that uses a USB camera. I am now having trouble running the Movimed cameras. Specifically, all of the AF-1501 VI's have broken arrows, as do the basic IMAQ VI's (i.e. IMAQ Create, IMAQ Close, etc.)

My question is: does the AF-1501 support both IMAQ and IMAQdx, and is there a preference between the two? Second, could having both drivers installed on the same computer mess something up?

I want to make sure I know roughly what is going on before I start making large uninstall/reinstall changes to the computer.

Thank you for your help,

Hi Alvin,

I hope that I can be of assistance to you with this post, but please note that Movimed may be the more appropriate support channel for this request, depending on what we find. What versions of IMAQ and IMAQdx do you have installed on your development system? For your development machine, there should be no issue with installing both IMAQ and IMAQdx. On the cRIO, there may be an issue due to system memory limitations.

To identify which scenario is more likely for your case, are the IMAQ VIs broken on VIs on your development machine, or only for VIs running on the cRIO? If the VIs are broken for your development machine as well, then there is probably an installation issue with VAS. Also, IMAQ does not require licensing, whereas IMAQdx does, so it looks like the issue is not related to licensing and activation since it is the IMAQ VIs that are broken.

If the VIs work fine on the dev. machine, but not when deployed to the cRIO, then one thing to check is that you have not used up the system memory of the cRIO. The newer versions of the Vision RT image files have more functionality compared to previous versions and thus take up more memory. If your cRIO is running low in memory, then it is possible that certain components of IMAQ are missing on the cRIO causing the broken run arrow that you are seeing.

With that in mind, you should not have any reason to install IMAQdx RT on the cRIO unless you are interfacing with an IP camera. If you do have IMAQdx RT installed on the cRIO and you are running low on system memory, please try uninstalling that component to free up some space. If this does not resolve the issue, hopefully someone else, especially Movimed, can provide more insight.
