how to acquire the MR triggering pulse

[smoothengine007]

I write a vi that required to acquire an MR triggering pulse to start (sync with the MR scanner). The general triggering pulse from the MR is 50 microseconds; and can be extended up to 500 microseconds. I am using USB-6221 digital port to acquire this pulse. However, it doesn't seem to catch this pulse. Would it be the hardware problem? I attached my vi; maybe I did something wrong in the vi.

Hi,

you have posted your question in the LabWindows/CVI forum - you might want to post it in the LabVIEW forum instead...

EDIT: once again my typing is too slow!

I am sorry JR,

if I only would have known that you were typing too, I certainly would have given you the advantage...  Next time I'll have a coffee first
