Can I connect two NI 9233 systems to one computer to acquire vibration data?

Hi, I was wondering if I could connect two NI cRIO 9233 systems to the same computer using USB ports and use Labview 8.5 to collect vibration data.

The best solution is to use the 9172 compact DAQ chassis for both the 9233 to reside in.  http://www.ni.com/dataacquisition/compactdaq/

you can use two of the USB-9233 in the same computer, however the ADCs between the two modules will not be synchronized
