PXI-6537 Digital Logic Family voltages are not changing.

[TestNinja]

I have an application that is using a PXI-1085 chassis with a PXI-6537 x 2 that will need ports at a different logic levels  of 2.5V and 3.3V.  After setting up a test application to prove i can change the digital family logic for each port i get a constant 3.3V.  I went into max and tried using the "Configure" for each card and didn't get any change as well.  The DAQmx version i'm using is 9.5.5 with 2012 Dev Suite (LV 2012). 

Attached is my example test VI for 4 different ports in which i need a different logic levels.

What can't i change the logic level of this card?

THanks,

Hi Eric,

Can you try the VI linked below and let me know if the logic levels change?

There are caviats to this property.  Once you write a bit, your locked into that family logic level.  To change it you must abort and go back to configure mode, then re-apply the family logic level.  As I though i could do this per port I was wrong, this settings is for the entire card.  If you have mixed signals for logic level, either you find a card that is level programmable or group your signals as needed.

I believe this issue is resolved.
