Sending external trigger on AI scan start

[Foeth]

I've a trio of E-series DAQ's synchonised with RTSI. Now I want to use the start of the acquisition to trigger an external device.

How do I route the "AI start scan" signal so that I may actually read it on a scope?

I've tried rerouting the AI start scan signal to the various PFI lines but it's not really working!

Dear Foeth,

What programming language are you using and which version of the NI-DAQ driver?

Hello RikP,

I'm using Labview 6.0 with NiDaq7.0

The RTSI modules are NiDAQ6 style (No DAQ-mx)

I now have a DIO line sending a short pulse prior to acquiring the signals from the DAQ's, but I cannot measure the delay.

For my little problem two solutions can be used: my program accepts an external trigger (over PFI0) or sends a trigger. I've spent some time paging through the helpfile but so far I've not been able get teh desired result (whcih I suspect is quite simple to achieve)
