Why would I have to change the config of my DAC boards from input to putput on certain programs?

[Sandian]

In order to get some of our programs to work, we have to open Measurment and Automation and change the DACs from input to outputs. The boards we are using AT AO-10 are Analog output boards. This does not always happen. Is there a step I am missing in my programming?

Hello;

To be honest with you, I've never heard of such thing.
Since the board you are using is an analog output board, it contaims only output channels, therefore, only analog output program samples will work with it.

You shouldn't have to worry about any extra configuration of the DACs.

This is what I don't understand. In order to get some programs to work properly, I have to open Measurment and Automation, right click the AT AO-10 Analog Output boards, open the test panel and change each boards channels from input to output. If I do not do this, I get no output when running my VI's. HELP

After having a field tech out we found a bug in MAX. to get around this we added a digital write to port VI and the analog channels work as expected.
