NI-HSDIO Stream to Disk possible with Edge Trigger?

Hi all,

 

I recently acquired a HSDIO PCI 6541, but I'm having some trouble with streaming data to the disk.

I downloaded and can use the basic VI from http://zone.ni.com/devzone/cda/epd/p/id/5271 (NI-HSDIO Stream to Disk (Acquisition) Using Win32 File IO).

 

My question is: Can I use edge triggering with the above VI (ftp://ftp.ni.com/pub/devzone/epd/ni-hsdioacquisition-basic.zip)?

Update: It is possible. I had the Advance Edge Trigger set incorretly. Working now.

 

Edit: I also upgraded the HSDIO drivers to 1.6 from 1.5.4.

Im trying to do the same thing with a PCI 6551.  Trying to generate from disk and acquire to disk at the same time, and i have it working with a SW trigger.  That leaves me to manually line up the generated data to the acquired data.

 

What id really like to get working is a HW trigger.  ive tried implementing the old gen PFI1 ->acq PFI2 using the start trigger/digital edge, but it just wont trigger.  I have verified the PFI1 edge is actually being sent.

 

Is this simultaneous streaming gen-acq possible with a HW trigger?

 

Please help if you can

 

thanks!
