Reading attributes of an IEEE 1394 cam

[freaklamarsch]

Hi,
I am having problems reading the attributes of my camera.
The camera is a Basler 602f which should be fully supplied by the IMAQ IEEE 1394 driver.

When I try to read any attribute, I am always getting an error that the attribute isn't supported.

What am I doing wrong?

Hi,

You just can read attributes supported from the camera.

You should also look first at example LabViewx.x\Examples\IMAQ1394example.llb\grab and Attributes Setup.vi.

I think this will help...

Hi ThorstenRo,
actually it didn't help 🙂

I have taken the code from that example.
Because the example fails always with a feature not present in camera message, I thought if I loop through all attributes, I would find the supported ones.

My mistake was that I had the Error In/Out connected to a shift register and not to an indexing tunnel so I got an error for every feature because the error of the first feature was looped around.

Anyway, thanks for your help,
Bernie

Hi again,
now my program is running fine, but the output is puzzling me a little bit.

The camera is listed as NI tested and approved under http://sine.ni.com/apps/we/nipc.ni_approved
So I thought I could use all the attributes available via the IEEE1394 VIs of LabView.

But when I run my VI, I get errors for features like brightness and gain which are listed in the camera's manual as standard features.

When I use the getFeatures VI I only get three supported Features which are Code 0 (couldn't find that in the online help), Gamma and Shutter.

Does that mean that I have to use the 1394 Read and Write VIs to access all the features of the camera?
What does NI tested and approved actually mean?

Have a nice weekend,
Bernie

If you look at the test panel in MAX, it should display all the supported features. If you can see it in MAX, there is a way to control it in LabVIEW.

If you can't see it in MAX, you probably need to use the Read and Write VIs.
