Acquisition Step in VBAI 3.6 Always Fails with Prosilica cameras

[avasil]

Camera - Prosilica

VBAI 3.6

Vision Acquisition SW 8.6

    NI-IMAQdx 3.2

I am acquiring from an IEEE 1394 Firewire camera in Vision Builder for Automated Inspection (VBAI) using IMAQdx.  I can acquire and see the image fine when I am configuring the acquisition step but as soon as I select OK the step fails and no image is acquired.

I can acquire completely fine in Measurement and Automation Explorer (MAX) and Vision Assistant just not after selecting OK for the acquisition step in VBAI.

This was apprently addressed in the Knowledgebase Document ID: 4A4MIAP6 and was supposed to be fixed!!!

I have played around with the setting the values (to values other than "0" (default for several Prosilica camera variables)), but it does not seem to help.

Additional information

Camera - Prosilica EC 1380

The camera works fine with VBAI 3.0. I found this issue as I am trying to upgrade my application to use VBAI 3.6.

Seems like, there is a mismatch in the way the camera settings are being written/saved/applied in VBAI IMAQdx call and what the camera is expecting.

Any help would be appreciated.

Thanks.

Hello Avasil,

I have VB 3.5 and a Prosilica EC655 camera.  I setup an acquisition step and generated the attached screenshot.  I could not duplicate the issue you have described.  I visited the NI download link and found that VB 3.6 was not avialable, VB 3.5 is still being distributed as the latest version of VB (not sure if this is a new development :),

Make sure that you are selecting "Acquire Image (IEEE 1394 or GigE)..." rather than "Acquire Image (IEEE 1394)".  I believe the latter uses NI's legacy firewire driver which does not support all of the camera features, framerates, etc, therefore it is not recommended unless you have an old camera using old firmware. 

Cheers,
PK

Hello Paul,

The link to VBAI3.6 is

This was released 8/08. I would appreciate it if you could download and try this.

Appreciate your help.

Thanks,

Hey Ashish,

The KB is a little off. It should say if there is a pull down with a blank value, select a valid value and then try. Does this help? If you're still having trouble, I'd be interested in talking with you. Could you post your email/phone number?

Thanks,

Brad

Hello Brad,

Thanks for looking into this. I have specifically set all the variables to either the "OFF" state or have specified values for them (> 0). Specifically, I set the values for Gain and Exposure Time to >0 and all the others are set to "OFF.

Thanks,
