Setting DIO lines to high impedance state

[SonarRob]

I would like to programmatically set my digital I/O lines on my DAQCard 6533 to a high impedance state using LabView. The manual states that the line drivers automatically set to high impedance on power-up or computer reset but I would like to change states within the program.

Hi,

Unfortunately there are no NI-DAQ driver calls to set your digital lines to high-impedance. You would probably need to use register-level programming to accomplish this.

Hope that helps. Have a good day.

Ron,

Thanks a bunch!

I looked at the links you sent for register-level programming and found nothing for the 653X series of instruments. Any other suggestions?

Hi Rob,

RLP programming would be the only way to accomplish this. If you go to http://ni.com/ask and submit a request for the RLP manual for your dio board, NI should be able to accomodate your request via email. Hope that helps. Have a good day.
