Where to Start with the NI PXI-7831R

8

ni.com

NI also provides cables for connecting the NI PXI-7831R directly to 
5B and SSR analog and digital signal conditioning backplanes. The 
NSC68-262650 plugs directly into the MIO connector on the PXI-7831R 
and routes the signals to connectors that can be attached directly to 5B 
backplanes for the analog signals and SSR backplanes for the digital 
signals. The NSC68-5050 plugs directly into the DIO connectors on the 
PXI-7831R and routes the signals to connectors that can be attached 
directly to SSR backplanes.

Refer to the 

NI PXI-7831R User Manual 

for more information on 

connecting I/O signals.

Caution

Connections that exceed any of the maximum ratings of input or output signals 

on the NI PXI-7831R can damage the NI PXI-7831R and the computer. Refer to the 

NI PXI-7831R User Manual

 for the maximum input ratings for each signal. NI is 

not

 liable 

for any damage resulting from such signal connections.

Getting Started Example

The following instructions guide you through running a simple example on 
the PXI-7831R. Running this example confirms that you have installed 
your software and hardware correctly, and it provides a brief introduction 
to using LabVIEW to program the PXI-7831R. This example uses the 
default FPGA VI, which is installed along with the NI-RIO software, and 
which is also programmed into the flash memory on the PXI-7831R before 
the device is shipped from the factory.

Note

The following example can be run by all users, even if you are not using the FPGA 

Module. However, if you are using the FPGA Module, you might wish to consult the 

LabVIEW FPGA Module Release Notes 

for more information on getting started with the 

FPGA Module.

Complete the following steps to open and run the example program.

1.

Launch LabVIEW.

2.

(Real-Time Module users only) Select the networked Real-Time PXI 
system from the 

Execution Target 

list in the 

LabVIEW

 dialog box to 

target LabVIEW to the Real-Time system containing the PXI-7831R.

3.

Click the 

Open

 arrow and select 

Examples

 from the pull-down menu 

in the 

LabVIEW

 dialog box. The 

Example Finder

 window appears.

4.

Select 

Directory Structure

 on the 

Browse

 tab to browse the examples 

by directory structure.
