Getting Labview to Aquire signals only an external swicth sends a

[rrd]

Thank you for the helps i have recieved from this group.

I have this problem:

My sensors chamber unit have an external switch controling the solenoid valves which i must depress before i start data acquisition. I now want this switch to send a signal to start the LabView program itself to start, and to stop data aquisition after a timed interval.

My program VI is attached.

My intention is to use the loop on the left to recognise the arrival of the signal/ pulse from the switch, finish execution, pass control to the loop on the right.
