DAQmx stops PCI firewire card

[Martin.D]

Hi all,

 

I have a PCI-6221 DAQ card here and am using LabVIEW 8.6 and DAQmx to start some counter and AO tasks. All that works fine. The problem is on the same PC we are using a PCI firewire card to control the Aerotech motion stages. When the DAQmx tasks start the Aerotech motion stages become disabled! I guess there is a watchdog function on the motion controllers updated by the firewire card and somehow NI DAQ trips that watchdog. We need to do some more investigation but thought I would post now to see if anyone has resolved similar issues.

 

TIA

Just an update -

Never really got to the bottom of this driver issue but worked around it by replacing the PCI DAQ card with a USB version.

Now all working as expected with zero code changes.
