multicard HSDIO 6552 vi "send software trigger"

[engwei]

Hi, I m currently doing a single card HSDIO 6552 for signal generation and acquisition, and I m using "send software trigger"vi to send a software script trigger to hardware script. Let say, hardware script:script MyScriptrepeat until scriptTrigger0generate wfm0end repeatend scriptIn single card, when I press the "send trigger" button, I will have my code to enable "send software trigger" vi to send a software trigger to hardware script. The generation of wfm0 will then stopped. But, how about if I need to implement it in multicard ? I need to do it by 5 6552 HSDIO cards. All of this cards will be in same chasis. Please help ..Thanks in advance..

Hi engwei,
In order to implement a script trigger for multiple 6552s I would recommend that you set up the original software script trigger and use the niHSDIO Export Signal.vi to export this script trigger to a desired PXI Trigger/RTSI Line. You can set up the script trigger for each device to occur based on a digital edge and have the source of the trigger be the line that you exported your trigger onto. You can find the signal exporting VI by going to NI-HSDIO>>Generation>>Utility>>niHSDIO Export Signal. You will have a single script trigger that is generated in software and routed to each device over the line you select. The devices will be configured to use the digital edge of this line as their script trigger.

Thanks for your reply, Steve. I am not fully understand your explanation yet. I will try your method and maybe I will get to understand it. Thanks.

Hi engwei,
I realized that I made a mistake when I was directing you to find the niHSDIO Export Signal VI in my previous post. You should go to NI-HSDIO>>Generation>>Configuration>>niHSDIO Export Signal. I wanted to correct this for you and additional people reading the forum. I have attached a VI that was saved for LabVIEW 8.0 that is a rough example of what I was describing. You should be able to implement this type of configuration to get the functionality you are looking for.
