2-D array defaults when starting vi

[boise_bob]

I am attempting to run a demultiplexer using this 2-D array (downloaded this vi example in a different forum).  There are 6 digital outputs going from USB 6009 to demultiplexer.  I am using the demultiplexer to switch 16 LEDs on/off in user defined pattern.  After changing the 2-D array to the deseried pattern for decoding the LEDs, I start the vi and the array changes back to the same defualt pattern that was with the original example.  Is there a way to save the array to the pattern I need for decoding the LEDs?  Part of the required pattern consists of leaving the 5th row high at all times (to enable latch to demultiplexer).

Thanks,

Bob

The only way you can change the pattern is by changing the numeric wired to the N terminal of the for loop. Clicking on elements on the array will obviously do nothing since it is an indicator. If you want to use it as a control, make it a control and eliminate the for loop.

This is basic stuff (and nothing to do with Multifunction DAQ). You might want to take some LabVIEW tutorials.

Dennis is of course correct. You need to use a control instead of an indicator.
