how to change camera exposure time for PCI-1426

[Sidd Goyal]

Hi

I am attaching the screen shot of MAX, which means that camera is being recognized by MAX. I can take pictures using MAX. I am not sure about the camera file. I really dont know what else communication problem it might have..

At least the model is regonized by the MAX "2M30-2x-2tap" or do you use another one? Hope not

Can you also post a screenshot of both "Acq Parameters" & "Cam attributes" tabs?

I'm curious what will be shown there.

I expect to see exposure time, shutter time and so there.

Try to change them and see if the grabbed images changes.

I would try a complete new VI to get the model number with no errors.

That way you will be sure about communications and way of working.

Please find the attached screen shot of camera attributes and acquisition parameters. There is nothing like shutter or exposure time in any of these tabs.

One more question : Does the "Interface Name" control contains the same camera name as in the MAX?

Hi Sidd,

You are correct.  The Interface name corresponds to the name in MAX.  Good luck!

Hey Kristien,

Can you please tell me where did i go wrong or how can I do it?

Thanks

Hi Sidd,

Can you please tell us if the value of your "Interface Name" control is the same as what can be seen in the MAX after "Channel 0"?

It should be "IMP-2M30H........" The dots represents something I can't see on the screenshot.

By default the "IMAQ Init.vi" set the value of "Interface Name" to "img0"

These two values must match!

Maybe you should post the whole vi at once.

It will be much easier for us to analyse your problem.

Hi

It is Channel0: IMP-2M30H-2x4x-2tap

Hi Sidd,

The Acquisition Parameters can be accessed through a property node- be sure to choose the IMAQ class by right clicking on the property node and going to Select Class >> IMAQ >> IMAQ.  

It looks like you were going about accessing the Attributes correctly- using  Get Attribute.vi and Set Attribute.vi.  Definitely check out the NI-IMAQ VI Reference Help on these functions.  

Also, here are some helpful documents that you may not have seen yet:

I hope this helps!
