Muti cards AI and AO

[navistar]

Hello Labview Experts:

I have two NI USB cards 9211A and 6211. I would like to use these two cards to achieve the following objectives: use 9211A  for temperature measurements, and use 6211 for voltage (pressure -> voltage) measurements. In addition to all AIs, I also need to generate two voltage AOs to drive my motors.

I tested two cards, they are working separately, but I use two DAQmax read, but only 9211 is working, 6211 has error message. Could any one please provide advice and example Labview VIs on this? Thank you in advance?

Hi navistar,

You have a similar thread on the DAQ forums at the following link:

I cannot get two USB cards worked at same time

Lets continue to work from this location since this appears to be a DAQ issue.
