How can output certain data each time when the trig is on?

[bluesky2000]

I tried to using PCI653X to output the pattern data as soon as there is a trig. The trig is repeated in certain frequency.So I need output those pattern data every times. I can do it if I use Visual C++. But I couldn't do it in Labview. It is only able to catch the first trig. I couldn't loop the DIO_WRITE and DIO_START. Always error code 10609. Any idea?

Hello;

You probably accomplished that task by having a Software based application in VC++. The correct way to do that is to use a counter board, and configure two counters of that board to execute a retriggerable pulse train, and then, the pulse train would be routed trhough the RTSI bus to be the PCLK of the 653x board.
