In addition to the items contained in the kit, you need the following items to install or operate your device.

NI SwitchBlock Carrier Required Items

• NI PXI chassis or NI PXI Express chassis with hybrid slots

• 1 Phillips screwdriver

Note You can install the NI PXI-2800 carrier for the NI SwitchBlock in an NI PXI Express chassis if the back connector of the carrier connects to a PXI peripheral slot in the chassis.

NI SwitchBlock Card Required Items

• NI SwitchBlock carrier

• 1 Phillips screwdriver

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 Hardware

• You must install the software before installing the hardware.
• Before you install the hardware, refer to the guidelines in the Maintain Forced-Air Cooling
• Note to Users at ni.com/manuals to ensure that the device can cool itself effectively.

Caution To prevent damage to the device caused by ESD or contamination, handle the device using the edges or the metal bracket.
Caution Clean the hardware with a soft, nonmetallic brush. Make sure that the hardware is completely dry and free from contaminants before returning it to service.

Installing an NI SwitchBlock Carrier

• The NI SwitchBlock carrier holds up to six NI SwitchBlock relay cards and occupies four PXI slots. The carrier can be installed before or after installing cards.

4. NI PXI/PXI Express or NI PXI/SCXI Combination Chassis

• Ensure the AC power source is connected to the chassis before installing the carrier.
  The AC power cord grounds the chassis and protects it from electrical damage while you install the carrier.

• Power off the chassis.

• If the chassis has multiple fan speed settings, ensure that the fans are set to high.

• Position the chassis so that inlet and outlet vents are not obstructed.
  For more information about optimal chassis positioning, refer to chassis documentation.

• Identify four adjacent empty slots in the chassis for the NI SwitchBlock carrier to occupy.

• Note The second-to-leftmost slot occupied by the carrier must be compatible with the PXI. The other three occupied slots may be any peripheral or timing slot. Refer to the chassis documentation for details.

• Remove the filler panels of the four slots you have selected for installing the carrier.

• Touch any metal part of the chassis to discharge static electricity.

• Place the carrier edges into the module guides at the top and bottom of the chassis. Slide the carrier into the slot until it is fully inserted.

• Tighten the screws at the top and bottom of the carrier front panel.
  Note Tightening the top and bottom mounting screws increases mechanical stability and also electrically connects the front panel to the chassis, which can improve the signal quality and electromagnetic performance.

• Cover all empty slots using filler panels or slot blockers to maximize cooling air flow.

Installing an NI SwitchBlock Card

The NI SwitchBlock carrier holds up to six NI SwitchBlock relay cards. The cards can be installed before or after installing the carrier.

• Screws
• NI SwitchBlock Card
• NI SwitchBlock Carrier

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.

3. If the chassis has multiple fan speed settings, ensure that the fans are set to high.

4. Position the chassis so that inlet and outlet vents are not obstructed.
   For more information about optimal chassis positioning, refer to chassis documentation.

5. Remove the filler panel of an unused slot in the NI SwitchBlock carrier.

6. Touch any metal part of the chassis to discharge static electricity.

7. Place the module edges into the module guides at the top and bottom of the carrier. Slide the device into the slot until it is fully inserted.

8. Secure the device’s front panel to the carrier using the front-panel mounting screws.
   Note Tightening the top and bottom mounting screws increases mechanical stability and also electrically connects the front panel to the carrier, which can improve the signal quality and electromagnetic performance.

9. Cover all empty NI SwitchBlock slots using the blank NI SwitchBlock filler panels.

10. Power on the chassis.

Configuring the NI SwitchBlock in MAX

• Use Measurement & Automation Explorer (MAX) to configure your NI hardware. MAX informs other programs about which devices reside in the system and how they are configured.
• MAX is automatically installed with NI-SWITCH.

1. Launch MAX.

2. In the configuration tree, expand Devices and Interfaces to see the list of installed devices.
   Installed devices appear under the name of their associated chassis.

3. Expand your Chassis tree item.
   MAX lists all devices installed in the chassis. Your default device names may vary.
   Note If you do not see your device listed, press to refresh the list of installed devices. If the device is still not listed, power off the system, ensure the device is correctly installed, and restart.

4. Record the device identifier MAX assigns to the hardware. Use this identifier when programming the NI SwitchBlock.

5. Right-click the carrier in the configuration tree and select Configure to launch the NI SwitchBlock Configuration Panel.
   By default, all NI SwitchBlock cards in the carrier appear as single-card devices, as shown in the following figure. Use one the following methods to configure your NI SwitchBlock and designate which cards compose each device:
   • Select Combine All or Uncombine All to combine NI SwitchBlock cards in the carrier into devices or to split all cards into single-card devices.
   • Right-click a card and select Move To»New Device to create a new device.
   • Drag and drop a card into the desired device to create a multicard NI SwitchBlock device.

6. Select OK to update the configuration tree in MAX.
   Note If a device name has not been previously specified in the MAX configuration tree, MAX will auto-generate a device name such as SwitchBlock1Dev1.

7. Self-test the device by selecting the device in the configuration tree and clicking Self-Test in the MAX toolbar.
   The MAX self-test performs a basic verification of hardware resources.

Programming the NI SwitchBlock
You can acquire data interactively using the NI-SWITCH Soft Front Panel (SFP), or you can control the device programmatically using the NI-SWITCH instrument driver. You can then use NI-SWITCH to program the device in the application development environment (ADE) of your choice.
