INTERFACING JAI CV-A1 CCD WITH NI1409 CARD

[RManion]

Hey there,

From the looks of the image, it appears as though the JAI utility and the JAI camera are having trouble communicating over the JAI cable (6 pin).

In my experiences with this camera, the red bar that you see at the bottom of your camera control utility means that serial communication with the device has failed. You may want to ensure that the com port you have selected matches the ID of the com port your JAI cable is connected to. When serial communication is properly connected, the red bar should turn green.

Other than that, I'm not too sure what to suggest. JAI might know a little bit more about their camera control utility.

Hope this helps,

Robert

Thanks. Now we are able to operate the Jai CV-A1 camera as shown in the *.jpg file. But we still had a problem with IMAQ acquisition. We are using IMAQ 3.1 received along with NI1409 card, while trying with this CCD, we got an error as

Error 0XBFF6001F
"CANNOT DETECT RECOGNISEABLE VIDEO SOURCE"

Again we request NI support to follow further.


Thanks

Please also see the JAICV-A1 and now it appears Green and able to achieve with 6pin to 9USUB serieal port

We have tried with lMAQ 2.5 and IMAQ 3.1. versions. We found the same error as shown in the following jpg file. We tried the procedure going through

Aquisition Error:
can't lock on video source"

Copy the JAI CV-A1(1409).icd file into the <NI-IMAQ>\Data folder. Go to ftp://ftp.ni.com/support/imaq/camera_support/camera_files/analog/jai/ to download this camera configuration file.
2. Launch Measurement & Automation Explorer (MAX).
3. Expand the Devices and Interfaces branch of the tree view.
4. Expand the IMAQ PCI/PXI-1409 branch of the tree view.
5. Right-click Channel 0: RS-170, and select Camera>>JAI>>JAI CV-A1.
6. Click Save.

But still we could not able to interface the Jai CV-A1. 

Now the camera is connected and it is now green.

Kindly provide us further support

Hello,

If you have configured your camera to operate in asynchronous reset mode, then you may not be able to test it in Measurement and Automation Explorer (MAX).  This is because you have to be sure that you are generating the necessary trigger signals that are required for the camera to operate in that mode.  MAX will not generate that trigger signal by default.  If you want to test the camera in MAX, be sure that you are running in continuous acquisition mode.

We have set the shutter mode in normal and all the parameters are have choosen to run in continuous acquisition mode as shown in the JaiCVA1_1.jpg as enclosed earlier. Please advise and let us know if any thing we missed.

Hello,

I saw in the image that you posted for the error that was occurring in MAX, that you were still using the IMAQ 2.5.  Update the driver version back to 3.1.  Then try downloading the updated version of the JAI camera file from the FTP site at:

ftp://ftp.ni.com/support/imaq/camera_support/camera_files/analog/jai/

Be sure to overwrite the existing version of the file.  Once you have done this, re-open the JAI configuration utility and configure it as you did before.  After you have established the serial connection to the camera, be sure to synchronize the camera every time you modify the values within the utility.  The synchronization process is how data is passed from the utility to the camera.  Also, try reducing the size of the image that you are attempting to capture.  Try acquiring an image that is roughly 640x480.  Does the problem persist?

Dear Robert

We have loaded IMAQ3.1 and tried to interface but the result is same as enclosed picture.  We could not able to download the file from the ftp site due to some restrictions. Is it possible to send this important file through e-mail: nkmohan@iitm.ac.in, if it is essential. Hope we will able to interface CV-A1 CCD with NI1409 which is important for our ongoing application and looking forward for your support.

Hello,

I have attached the camera file for the JAI CV A1 that will work with the PCI 1409.  Try downloading this and overwriting the camera file that exists in C:\Program Files\National Instruments\NI-IMAQ\Data.  Then open MAX and be sure that the camera file selected is still the one for the JAI CV A1.  Then try opening and running the JAI configuration utility and running the acquisition in MAX.
