Solution
To use the NI 9151 with your R Series device, use the SHC68-68-RDIO cable to connect the expansion chassis to any of the DIO connectors on the R Series device.
NOTE: Refer to the
R Series Cable and Accessories Compatibility guide to determine what R Series devices are compatible with the NI-9151.
With multifunction R Series devices (NI 783xR, NI 784xR, NI 785xR), you can connect up to two R Series expansion chassis for a maximum of eight I/O modules per R Series device. With digital R Series devices (NI 781xR), you can connect up to four R Series expansion chassis for a maximum of 16 I/O modules per R Series device.
To configure your LabVIEW FPGA application to recognize the C Series modules in the expansion chassis, do the following:
For LabVIEW 8.x and later
- With the expansion chassis properly cabled to the R Series device, power up the PXI controller or desktop PC system.
- Create a new project or open your existing project.
- Right-click on My Computer in the Project Explorer window and select New»Targets and Devices... Then, select Existing Targets and Devices, select your R Series Device from the list and click OK.
- Right-click on the newly-created FPGA Target under My Computer, and select New»R Series Expansion Chassis.
- In the dialog window that appears, select the connector to which you have cabled the NI 9151 expansion chassis and click OK. Optionally, choose to discover C Series modules now. Otherwise, add them in steps 6 and 7.

- Right-click on the newly-created Expansion Chassis and select New»C Series Modules...
- Select Existing target or device, expand C Series Module, select Continue when prompted to halt FPGA code, select all of the detected modules, and click OK.
- Right-click on the newly-created modules and select New»FPGA I/O. Add all of the desired Analog and Digital I/O and click OK.

For LabVIEW 7.x:
- With the expansion chassis properly cabled to the R Series device, power up the PXI controller or desktop PC system.
- Launch LabVIEW and select the R Series device from the Execution Target list.
- Create and/or load a LabVIEW FPGA project into the Embedded Project Manager.
- Open the Configure Target for CompactRIO window, Hardware»Configure Target for CompactRIO..., to display which CompactRIO modules are on each connector.
- Press the Discover Modules button and select all connectors cabled to an expansion chassis.
- Once the modules are found, click OK.
Once you have completed the steps above, your R Series device is fully configured to use the NI 9151 expansion chassis.
