there is a black shadow on one third (right hand side) of the image off the CV-M1 prog scan from JAI while using it with IMAQ NI1409 board.The camera is connected in lock mode using the 12 pin hirose conector. The IMAQ-A6822 BREAK OT BOX is being used with the 68-pin VHDCI male connector for the 1409 board. Any ideas wat the shadow is due to and how to get rid of it ?????

Usually when there is a large black section along the edge of an image, the image window just needs to be shifted a bit. If you go into MAX and click on the Channel's Properties, you'll see inputs for Window Size (Left, Top, Width, Height). You should be able to adjust these until the entire image is valid.

If you can't adjust the window to the correct position and resolution, but the acquision never times out, then the camera may actually be sending black pixels to the frame grabber.

Please keep me updated.

The black section is more than an edge it is practically covering 1/3 of the whole image !!!!
I tried shifting it around using the properties with no practical result. It is not the camera either as the the image from the camera in testing with other software is clear.

NI techs came back with the following :

The older version of the 1409 which i have can only handle 1024 by 1024 .. as the camera is 1030 by 1300 the 1409 framgraber only reads the first 1024 and then resets ( the mentioned the U12 on the 1409 ) ... I dont know if this is the real problem but I have learned from past experience that information from tech support at NI ( UK atleast) is not what could be called reliable.

please advice ....

thanking you for your time and effort

Are you seeing ~1024 good pixels per line with a vertical band on the right side (~276 pixels wide) that is somewhat darker?

If so, this is a known issue with a small number of the 1409 boards and is only a problem with image widths greater than 1024. You will need to return your board for repair. Please contact National Instruments and reference CAR 2HS9LI29 when you speak with an applications engineer.

That is what I have done . Now I know I am on the right track. Thanx alot for your help.

[Kyle_V]

In this case, Ammar, the UK Support Team is right. After the 1024th horizontal pixel, the black reference value resets to the current image value. This has the effect of making every pixel after 1024 darker. This behavior is only seen on older PCI-1409 boards and then only with cameras with a horizontal resolution greater than 1024, so the vast majority of users will never notice any difference.

You should call the UK branch immediately to arrange an RMA.

I have just recived the supposedly new (revised) version of the 1409. But I am still facing the same problem. This is turning out into a nightmare. Have national Instruments ever got the 1409 to work with the CV-M1 JAI with no errors. I dont think so !!!!

any one got any ideas .. anything that NATIONAL INSRUMENTS have not tried yet ????????

[Kyle_V]

If the image is still turning dark at the 1024th horizontal pixel, then the board may not have been fixed or replaced correctly. Could you please reply with the assymbly number of the 1409. It should start with 18 and end with a letter. That letter determines your revision.

If the image is not turning dark at th 1024th pixel, then we need to dig a little deaper. Could you attach an image of what you're seeing to your reply, so I can analyze it here?

Thanks for you patience

The image is still dark at the 1024th horizontal pixel.

The assymbly part number is 186914B-01.

It is a revision B board.

It should be replaced with a revision D board.

As there is no standerd cable for the camera when in external lock mode. what is the best way to connect the 68-pin VHDCI to the 12 pin hirose. Keeping in mind that we are dealing with an analouge camera but expecting picture qaulity for machine vision inspection standerds.

plz advice.
