How to acquire images from several PXI-1428 boards with trigger snap acquisition using RTSI bus.

[Jsuzuki]

Hello.

I am trying to acquire simultaneous images from several PXI-1428 boards and cameras. One image must be stored on each PXI-1428s, so number of stored images should be equivalent with PXI-1428’s. Continuous acquisition must not be required.

I must use JAI’s CV-A10CL and CV-M2CL/CCD cameras, one PXI-6602 board for trigger input, MXI-4 System, Visual Basic 6, and Measurement Studio. And I also must use RTSI bus for trigger I/O from a PXI-6602 to PXI-1428s. I want the just sample program. Can I get it?

Regards.

Dear Mr. Suzuki, Unfortunately we don't have the just sample that you are looking for. If you have any LabVIEW environment you can go through the following process. There are many LabVIEW examples that can help you out. If you can convert the LV examples into VB code, then that should help. So, please take a look at the LabVIEW example called "HL Grab with two boards.VI". This is a good example that shows how to trigger acquisition from two boards. Then you can also look at the LL Triggered Ring.VI, or LL Triggered Snap.VI and combine the functionality from the HL Grab with two boards for the multiple board triggering. If you don't have LabVIEW, you can break down the code into smaller pieces so that one part you can use a trigger to acquire an image from one board, then another piece to just acquire from multiple boards, not using a trigger, then combining the code together. For reference you can try the following sample program. Triggered Acquisition.vbp in C:\Program Files\National Instruments\NI-IMAQ\Sample\VB\Trigger   Sincerely P.Das
