Configuring 8 nos. of SCXI-1520 card to be acquired by DAQ boards in a PXI-1011 chassis

[Nirmal_Sharma]

Hi,
I have a single PXI-1011 combo chassis in which I am putting 8 no. of SCXI-1520 cards. I have following doubts in configuring all the channels of scxi modules to DAQ boards as below:

1. For parallel mode interface, what condition should be met ? Is it the total no. of channels of DAQ boards equal to total no. of channels of SCXI modules or no. of DAQ boards equal to the no. of SCXI modules ?

2. Suppose i am putting 2 nos. of PXI-6071E (64 diff. channels), can i make one-to one connection of scxi channels (64 channels) to pxi channels(64 channels) ?

3. Or if i am putting 1 no. of 6070E(8 diff channel), can I multiplex zeroth channel of each scxi card to zeroth channe
l of PXI card. Similarly multiplexing remaining channels of scxi card to rest channels of pxi card will work ?

Nirmal,

Each SCXI module being used in parallel mode needs to be cabled directly to a separate E-Series device. This poses a problem in your situation because the PXI-1011 combo chassis does not provide access to the back of the SCXI side where the connections need to be made. If you insert an E-Series device in the right-most PXI slot of your PXI-1011 chassis, and operate all of your SCXI modules in multiplexed mode, every channel from each of the modules will be multiplexed to a single channel on the E-Series device (a dedicated backplane channel used with the SCXI side of a PXI-1011 or PXI-1010 combo chassis).

Good luck with your application.
