Serial communication with visa, need help

Solved!

I don't think you understand the behavior of the mechanical action button property on boolean controls.  I suggest you take some tutorials.

 

You want Latch When Released.  You press, you let go.  It fires a single value change event.  When LV gets to reading the terminal, then it will automatically pop the button back to its default state.

 

You don't have any tunnels in your event structure now.  What wires do you have that you don't want the value to change?  When you do have something, then you have that wire connect to a shift register on the loop.  When you want it to maintain the same value, then you just wire through from input tunnel to output tunnel on any case or event structures.
