When I try to use the Vision Acquisition vi, I get an error message saying that " The system did not receive a test packet from the camera."

Error -1074360271 occurred at IMAQdx Start Acquisition.vi

NI-IMAQdx: (Hex 0xBFF69031) The system did not receive a test packet from the camera. The packet size may be too large for the network configuration or a firewall may be enabled.

Did you try reducing the packet size to 1500 bytes? Did you check if the Windows Firewall is enabled?

Yes -- same result.  I have the Pleora Analog-Pro GigE IP engine and the video works fine with the GEV software that comes with it.

Can you try removing any Pleora filter drivers that are installed?

Eric

[Ortnip]

Tried that too.  No joy.

Did you try disabling test packets?  I know Basler cameras have a "Enable Test Packets" setting buried in Advanced Network settings or something like that.  You have to change the setting in MAX to show all settings instead of just acquisition, then locate the setting.  I have been told regularly that the setting must be turned off for Basler cameras to work properly.  Perhaps your camera has the same setting and the same requirement.

A very specific firmware revision for certain Basler cameras had an issue where the test packet would not be sent for certain packet sizes and certain specific conditions, causing a false report of a test packet failure when a normal acquisition would in fact succeed. However, this was fixed in later firmware revisions and I have never seen a similar issue on any other types of cameras. 

Aside from this specific case, if a test packet fails, it generally means an acquisition will as well. Given that Pleora's software can acquire, we can rule out networking topology and hardware, assuming you are using the same packet size as the Pleora software is. The only other thing that would seem a likely candidate would be a software issue like a firewall or some other filter driver that is interefering with IMAQdx receiving the data.

Here is where I'm at.  I do get an image (one image) when I change the packet size to 1400.  Please advise where to go from here.

Thanks.

Your generated Express VI code includes a saved copy of the camera settings. It is set to a packet size of 8000 in that code. Also, the VI you attached is the express VI-generated code. It is disigned to be run inside of a loop if you want to acquire multiple images continuously. If you run it only once you will get one image.

In general, it is easier to use MAX to configure and test your camera settings. Once it is working there then you can move to acquiring in Labview and not have to worry about the acquisition side not working.

Thanks Eric.  Here's the latest:

As you can see from the grab.  I am able to get an image in but it seems squashed vertically.  When I run the vi, it is even more squashed.  When I look at the video using the GEV software from Pleora, I see no distortion (720x240).  What am I doing wrong?
