Products Covered
This document covers the following products:
• PXIe-8238 (142470x-010L)
Note Following the model number above is the specific NI assembly number in
parentheses. Ensure that the specifications of interest match the NI assembly number
printed on the board. x denotes all letter revisions of the assembly.
Getting Started
This section includes instructions for unpacking and installing your PXIe-8238 module. It also
describes the module's front panel connectors.
Unpacking
The PXIe-8238 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 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.
3. Notify National Instruments if the device appears damaged in any way. Do not install a
damaged device into your chassis.

Preparing the Environment
Ensure the environment you are using the PXIe-8238 in meets the following specifications.
Ambient temperature range 0 °C to 55 °C (Tested in accordance with
IEC-60068-2-1 and IEC-60068-2-2.)
Relative humidity range 10% to 90%, noncondensing (Tested in
accordance with IEC-60068-2-56.)

Pollution Degree 2
Indoor use only.
Note Refer to the PXIe-8238 User Manual for full PXIe-8238 specifications.
Hardware Installation
The following are general instructions for installing the PXIe-8238.
Complete the following steps to install the PXIe-8238 in your PXI Express chassis.
1. Power off your PXI Express chassis, but leave it plugged in while installing the
PXIe-8238. The power cord grounds the chassis and protects it from electrical damage
while you install the module.
Caution To protect both yourself and the chassis from electrical hazards,
leave the chassis off until you finish installing the PXIe-8238.
2. Remove or open any doors or covers blocking access to the slot in which you intend to
install the PXIe-8238.

3. Touch a metal part of the chassis to discharge any static electricity that might be on your
clothes or body.
4. Make sure the injector/ejector handle is in its downward position. Be sure to remove all
connector packaging and protective caps from retaining screws on the module.
5. Identify the slot in which the PXIe-8238 will be installed in the chassis. Refer to the
following table to determine which slot types the PXIe-8238 is compatible with.

6. Align the PXIe-8238 with the card guides on the top and bottom of the slot. Hold the
handle as you slowly slide the module into the chassis until the handle catches on the
injector/ejector rail.
Caution Do not raise the injector/ejector handle as you insert the PXIe-8238.
It will not insert properly unless the handle is in its downward position so that it
does not interfere with the injector/ejector rail on the chassis.
7. Raise the injector/ejector handle until the module firmly seats into the backplane
receptacle connectors. The front panel of the PXIe-8238 should be even with the front
panel of the chassis.
8. Tighten the bracket-retaining screws on the top and bottom of the front panel to secure
the PXIe-8238 to the chassis.
9. Replace or close any doors or covers to the chassis.
Powering On the PXIe-8238
The PXIe-8238 powers on automatically when the chassis is powered on. To power on the
PXIe-8238, turn on the chassis.
Powering Off the PXIe-8238
The PXIe-8238 powers off automatically when the chassis is powered off. You also can power
off the PXIe-8238 by shutting down the system controller.
Software Installation and Configuration
The PXIe-8238 requires driver software to enable its features. For software installation
instructions, go to ni.com/downloads, enter PXIe-8238 in the Downloads text box, and click
the search button.

nonmetallic brush for cleaning around components.
Make sure the module is completely dry and free from contaminants before returning it to
service.
Common Configuration Questions
This section answers common configuration questions you may have when using a PXIe-8238
module.
General Questions
What do the LEDs on the front panel mean?
Refer to the LED status descriptions in the Front Panel Features section.
My system boots fine as long as a particular module is not in my
chassis.
The most common cause of this is a damaged module. Try the module in a different chassis or
with a different controller. Also, remove any external cables or terminal blocks connected to
