SCXI™Switch Modules
This document explains how to install, configure, and set up a National Instruments SCXI
switch module. Your NI SCXI switch module ships with the NI-SWITCH instrument driver,
which you can use to program the device.
This document contains information about the NI-DAQmx driver software, which you can
also use to program NI switch modules. Launch NI-DAQmx from the Start menu, or for
Windows 8, from NI Launcher.
Note The protection provided by your NI switch product can be impaired if used
in a manner not described in this document.

Unpacking
Your NI switch product ships in an antistatic package to prevent electrostatic discharge from
damaging device components. To prevent such damage when handling the device, ground
yourself using a grounding strap or by holding a grounded object, such as your computer
chassis, and complete the following steps:
1. Touch the antistatic package to a metal part of the computer chassis before removing the
device from the package.
Caution Never touch the exposed pins of connectors.
2. Remove the device from the package and inspect the device for loose components or any
other sign of damage.
Notify NI if the device appears damaged in any way. Do not install a damaged device into the
chassis.
Installing the Software
You must install the NI-SWITCH driver software before installing the NI switch product.
NI switch modules are packaged with NI-SWITCH and NI-DAQmx. Each driver has its own
API with a library of VIs and functions you can call from your ADE to program your NI
switch product.
1. Optional: If you are developing an NI-SWITCH application, install an ADE, such as
LabVIEW or LabWindows™/CVI™.
2. Install the latest service packs for your operating system.
3. Insert the NI-SWITCH DVD into the DVD drive.
The NI-SWITCH installer should open automatically. If the installation window does not
appear, navigate to the DVD drive, double-click the drive, and double-click
autorun.exe.
4. Follow the instructions in the installation prompts to install the NI-SWITCH driver
software.
5. When the installer completes, select Restart in the dialog box that asks if you want to
restart, shut down, or restart later and remove the driver software DVD.

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 included with the module to ensure that the device can cool itself effectively.
This document is also available at ni.com/manuals.
Caution NI SCXI switch modules are sensitive instruments that should be handled
carefully. 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.
To select and install a switch controller, complete the following steps:
1. Verify that your switch controller supports the switch module you want to install. Refer
to the following table.

Note Some switch controllers, like the NI USB-1357/1358/1359, can connect
an NI SCXI switch module directly to a computer. Alternatively, a switch
controller installed in the rightmost PXI slot of an
NI PXI-1010/1011/1050/1052 chassis does not require any additional cables or
adapters to connect to the switch module.
Note The NI 4060 device can only control the
NI SCXI-1127/1128/1129/1160/1161/1163R/1190 switch modules configured
using Traditional NI-DAQ (Legacy).
2. Identify the adapter kit(s) required to cable the switch controller or the computer to the NI
SCXI switch module.
3. Determine the appropriate installation procedure for installing your NI switch module.
Refer to the following table.

2To use this module with the listed controllers, set jumpers W2, W3, and W4 on the NI switch
module to MIO. Refer to the NI SCXI-1160/1161 Jumpers Note to Users or the NI Switches Help
for more information.
3An NI USB device can control these switches when cabled to a 10-pin rear connector NI SCXI
switch module in the same chassis. NI USB switch controllers cannot be used with an
NI PXI-1011 or an NI PXI-1052 chassis.

controller documentation.
Note Ensure the chassis is still powered off before continuing to install your
switch module.
3. Set the chassis address switches to the OFF position. If you are using multiple SCXI
chassis, ensure each chassis has a unique binary address.
Note Earlier chassis use jumpers inside the chassis front panel instead of
chassis address switches. Earlier chassis also differ in fuses and AC power
selection. Refer to the documentation specific to your chassis for more
information.
4. Confirm the correct power settings of the chassis (100, 120, 220, or 240 VAC).
5. Remove the filler panel from an unused SCXI slot.
6. Touch any metal part of the chassis to discharge static electricity.
7. Insert the switch module into the SCXI slot.
8. Screw the switch front panel to the chassis front panel mounting rail.
