digital input pin transition

I am in need a help fellow Labview users. I am using an external controller board with a digital pin that will used to synchronize thermocouple temperature measurements.

In doing this the following is the logic I am trying to implement.

1. Detect a low to high pulse transition
2. Then, start a timer
3. Detect, high to low pulse transition
4. Then, stop timer
5. Then record time delta

I am using a NI-6009 multichannel I/O module

I truly do appreciate help with this!
