Nigel,
The most likely way to do this would be to use occurances (my guess anyway).
If you have these events in some sort of loop and or /structure, I would guess
that it goes ri
ght from 1) to 2) to 3) so fast you can not see it.
#1 would be something like set Bool true, then wait for occurance of trigger
(I assume from the vi that does #2)
The trigger/capture portion sets occurance for #1, and #2 (#1 off, #2 on)
when the data capture is complete set occurance for #2 and #3 (#2 off #3 on).
I cant tell you haow to mod the VIs mentioned, I dont have them and they wont
run on my unix box (presumabley)
