Dear Charel,
you need the NI-DAQ 6.9.3 driver to work with your hardware on LabVIE 6.1.
You must configure your SCXI Chassi in MAX.
Devices and Interfaces, click at traditional Devices and add your SCXI Chassi. After you have do that, configure the SXCI moduls.
You can create, furthermore additional virtual channel for your measurement.
Hope this helps,
best regards.
