How Do I write only one DO line when I have all lines for all ports added to the task?

[VisualMath]

I am using the 6515 DIO card.  There are linesthat I don't want to change, so I want to skip writing them (no change) as I do not know their state.  At a later time I might want to write the skipped lines and then skip other lines (no change).

Goslow,

Thanks for contacting National Instruments.  There is a KB on this issue I beleive would help you.  It explains how to overcome the lack of masking in DAQmx.  Le tme know if you have any more problems.

AK2DM,

Sorry about that.  I made a simple mistake in the url, try this one.
