Questions about channel-scanning operation in multiplexed mode

[hanwei]

Hi group:

We want to develop a data acquisition system by NI PCI 6040E, and we also have SCXI-1001 chasis, SCXI-1102 module and SCXI-1300 terminal box. You know, the PCI 6040E is equiped 16 channel analog input, is it possible, if I want to collect 32 channel signal by using channel-scanning operation in multiplexed mode in SCXI-1102 module?

And how to implement it, is there any documents about it?

Thanks  a  lot

Best regards

Wei

Here is the the user manual of SCXI 1102.

In the Theory of Multiplexed Operations section describes how the device is multiplexed to a DAQ card

And this Link illustrates how to connect the hardware and How to initiate communication between SCXI Chassis and DAQ card, using Measurement and Automation Explorer

( although it describes in context of ConnectionThermocouples, the same logic holds good for analog signals as well)

Anymore doubts, do ask

Regards,

Dev
