The connection may be tight, but do not force the adapter module into place.
2. Tighten the captive screws on the NI FlexRIO adapter module to secure it to the
NI FlexRIO FPGA module. NI recommends using the laser-tipped screwdriver (part
number 748677-01) included in the NI 5741 packaging.
3. Launch LabVIEW to begin configuring your NI FlexRIO system.
Connecting Cables
• Use any shielded50 Ω SMA cable to connect signals to the connectors on the front panel
of your NI 5741
• Use the SHH19-H19-AUX cable (NI part number: 152629-01 or 152629-02) to connect
to the digital I/O (DIO) and programmable function interface (PFI) signals on the AUX
I/O connector. NI recommends using the SCB-19 connector block to access the DIO and
PFI signals.
• Use the NI SHC68-C68-D4 VHDCI cable (NI part number: 196275-01) to connect to the
AO 0-15 connector.

Removing the Adapter Module
Complete the following steps to remove the adapter module from the FlexRIO FPGA module.
Disabling the Adapter Module in LabVIEW FPGA
To properly remove an adapter module from the FlexRIO FPGA module, you must disable the
adapter module within the LabVIEW FPGA user interface. To disable the adapter module
within LabVIEW, complete the following steps.
1. In your LabVIEW Project Explorer window, right-click the IO Module item under the
FPGA Target and select Properties to display the IO Module Properties dialog box.
2. Click the Status category to view the adapter module Status dialog.
3. Deselect the checkbox for Enable IO Module Power. When this option is deselected,
firmware tristates the FlexRIO I/O and disables all adapter module power rails.
4. Click OK.
Uninstalling the Module
Caution If the module has been in use, it may exceed safe handling temperatures
and cause burns. Allow the module to cool before removing it from the chassis.
1. Disconnect any cables from the module front panel connectors.
Caution Disconnect any external clock or digital connections to the device
front panel. Applying external signals while the device is powered off may
cause damage.
2. Power off the chassis.
3. Ground yourself with a grounding strap or touch a grounded metal surface.
4. Unlatch the module by pushing down on the ejector handle.
5. Hold the module by the ejector handle and remove it from the slot.
Store the module in the original antistatic packaging when not in use to avoid damage.
Installing Accessories
The NI SMB-2152 is a breakout box accessory for debugging your NI 5741. The NI part
number for the NI SMB-2152 is 189408F-08L.

Component-Level Intellectual Property (CLIP)
The LabVIEW FPGA Module includes component-level intellectual property (CLIP) for HDL
IP integration. NI FlexRIO devices support two types of CLIP: user-defined and socketed.
•User-defined CLIP allows you to insert HDL IP into an FPGA target, enabling VHDL
code to communicate directly with an FPGA VI.
•Socketed CLIP provides the same IP integration of the user-defined CLIP, but it also
allows the CLIP to communicate directly with circuitry external to the FPGA. Adapter
module socketed CLIP allows your IP to communicate directly with both the FPGA VI
and the external adapter module connector interface.
The FlexRIO adapter module ships with socketed CLIP items that add module I/O to the
LabVIEW project.
CLIP and LabVIEW FPGA
The interface between the NI 5741 CLIP and LabVIEW FPGA in the following figures.
If you are using an NI FlexRIO FPGA module with a Virtex-5 FPGA, refer to the following
figure, which shows the relationship between the CLIP and an FPGA VI configured for use
with a Virtex-5 FPGA target.
