Why do I receive error code "-1074118644" when trying to initialize the 2532 Matrix?

Question

I am using the VI "IviSwtch Initialize With Options.vi". I created a logical IVI name (MATRIX), and am passing the following option string: "Simulate=0,RangeCheck=1,QueryInstrStatus=0,Cache=1,DriverSetup=Topology:2532/1-Wire 4x128 Matrix". I tried variations of this with no luck. I configured the matrix in MAX with the same topology as shown above. My software versions are:
IVI Compliance package 2.1.2
LabVIEW 7.1
NI-SWITCH 2.30.49153
VISA 3.1
NI-DAQ 7.3

Thanks for the response Greg. I did finally get it working, but I had to use the "PXI1Slot8" format for the resource descriptor rather than "PXI2::9::INSTR". I don't know if that is typically what you are supposed to do, but that cleared the error.
To answer your questions, there's only one 2532 in the system. There is a 2566 in there as well. The configuration I was referring to was the IVI Driver configuration in MAX, not the DAQmx configuration, although I did select the TB-2640 under the DAQmx configuration, so it did default to the 1-Wire, 4x128 matrix as well.
