Other Equipment
There are several required items not included in your device kit that you need to install or
operate the NI 5695.
Required Items
• A PXI chassis and chassis documentation. The NI PXI-1045 chassis is one available
option for your device. For more information about compatible chassis options, refer to
ni.com.
• A PXI embedded controller or MXI controller system that meets the system requirements
specified in this guide and chassis documentation.
Optional Items
• A 1 N · m standard SMA torque wrench (NI part number 780487-01).
Installing the Software
You must be an Administrator to install NI software on your computer.
1. Install an ADE, such as LabVIEW or LabWindows™/CVI™.
2. Insert the driver software media into your computer. The installer should open
automatically.
If the installation window does not appear, navigate to the drive, double-click it, and
double-click autorun.exe.
3. Follow the instructions in the installation prompts.
Note Windows users may see access and security messages during
installation. Accept the prompts to complete the installation.
4. When the installer completes, select Restart in the dialog box that prompts you to restart,
shut down, or restart later.
Installing the NI 5695
Caution To prevent damage to the device caused by ESD or contamination, handle
the device using the edges or the metal bracket.
Note Ground yourself with a resistor-isolated wrist strap before installing the
module, before touching the center pin of any connector, and before removing or
adjusting any connections to the module.
1. Ensure the AC power source is connected to the chassis before installing the modules.
The AC power cord grounds the chassis and protects it from electrical damage while you
install the modules.
2. Power off the chassis.
