Safety Guidelines
Caution You can impair the protection provided by the NI-7932R if you
use it in a manner not described in this document.
Electromagnetic Compatibility Guidelines
This product was tested and complies with the regulatory requirements and limits
for electromagnetic compatibility (EMC) stated in the product specifications. These
requirements and limits provide reasonable protection against harmful interference
when the product is operated in the intended operational electromagnetic
environment.
This product is intended for use in industrial locations. However, harmful
interference may occur in some installations, when the product is connected to a
peripheral device or test object, or if the product is used in residential or
commercial areas. To minimize interference with radio and television reception and
prevent unacceptable performance degradation, install and use this product in strict
accordance with the instructions in the product documentation.
Furthermore, any changes or modifications to the product not expressly approved
by National Instruments could void your authority to operate it under your local
regulatory rules.
Caution To ensure the specified EMC performance, operate this product
only with shielded cables and accessories. The DC power input cables and
optical SFP+ cables may be unshielded.
Caution To ensure the specified EMC performance, you must use an
isolated cable with the SFP+ ports.
Caution To ensure the specified EMC performance, the length of any
cable connected to the TRIG ports and REF CLK ports must be no longer
than 3 m (10 ). The length of copper cables connected to the SFP+ ports
must be no longer than 3 m (10 ). The length of cables connected to the
© National Instruments 5
NI-7932
USB device ports or host ports must be no longer than 30 m (100 ). The
lengths of Ethernet cables and optical SFP+ cables are not limited.
Caution The USB device port is intended only for use in device
configuration, application deployment, debug, and maintenance.
Verifying the System Requirements
To use the NI-7932R, your system must meet certain requirements. For more
information about minimum system requirements, recommended system, and
supported application development environments (ADEs), refer to the readme,
which is available on the soware media or online at ni.com/updates.

2015 are the earliest versions of soware that support the NI-7932R.
Unpacking the Kit
Caution To prevent electrostatic discharge (ESD) from damaging the
device, ground yourself using a grounding strap or by holding a grounded
object, such as your computer chassis.
1. Touch the antistatic package to a metal part of the computer chassis.
2. Remove the device from the package and inspect the device for loose
components or any other sign of damage.
Caution Never touch the exposed pins of connectors.
Note Do not install a device if it appears damaged in any way.
3. Unpack any other items and documentation from the kit.
Store the device in the antistatic package when the device is not in use.

Preparing the Environment
Ensure that the environment you are using the NI-7932R in meets the following
specifications.
Operating temperature (IEC 60068-2-1, IEC 60068-2-2) 0 °C to 55 °C
Operating humidity (IEC 60068-2-56) 10% to 90% RH, noncondensing
Pollution Degree 2
Maximum altitude 2,000 m at 25 °C ambient temperature
Indoor use only.
Note Refer to the NI-7932R Specifications at ni.com/manuals for
complete specifications.
Caution Clean the hardware with a so, nonmetallic brush. Make sure
that the hardware is completely dry and free from contaminants before
returning it to service.
Wiring Power to the NI-7932R
The NI-7932R requires a 9 V to 30 V external power supply that meets the
specifications in the NI-7932R Specifications. The NI-7932R filters and regulates
the supplied power and provides power for the I/O modules.
Note You can latch the power plug to the NI-7932R using two screws
tightened to 0.20 to 0.25 N · m (1.8 to 2.2 lb · in.) of torque.
The maximum wire gage accepted by the power connector plug is 16 AWG. You must
use a stripped wire length of 10 mm (.394 in).
When the POWER LED on the front panel is lit green, the device is powered.
The NI-7932R has reverse-voltage protection.
Complete the following steps to connect a power supply to the NI-7932R.
1. Ensure the power source is turned o.

2. Connect a positive wire to the positive terminal of the power connector plug,
and connect a negative wire to the negative terminal of the power connector
plug.

3. No connect
3. Install the power connector on the front panel of the NI-7932R.
4. Turn on the external power source(s).
Powering on the NI-7932R
When you apply power for the first time to the NI-7932R, the controller boots into
safe mode. The POWER LED illuminates, the STATUS LED illuminates briefly, and
then the STATUS LED blinks twice every few seconds.
Aer you install soware on the controller, subsequent reboots will boot the
controller into the NI Linux Real-Time operating system.
You can optionally configure the NI-7932R to launch an embedded stand-alone
LabVIEW Real-Time application each time you boot the controller.
STATUS LED
The STATUS LED is o during normal operation. The NI-7932R indicates specific
error conditions by flashing the STATUS LED a certain number of times every few
seconds, as shown in the following table.
LED State Indication
2 flashes every few
seconds
There is no soware installed, which is the out-of-box state, or the controller
has detected an error in its soware.
An error can occur when an attempt to upgrade the soware is interrupted.
Refer to the MAX Help for information about reinstalling soware on the
controller.
© National Instruments 9
NI-7932
LED State Indication
3 flashes every few
seconds
The controller is in safe mode. Refer to the MAX Help for information about
safe mode.
4 flashes every few
seconds
The soware has crashed twice without rebooting or cycling power between
crashes. This usually occurs when the controller runs out of memory.
Review your Real-Time VI and check the memory usage. Modify the VI as
necessary to solve the memory usage issue.
Continuously
flashing
The controller has not booted into NI Linux Real-Time. The controller either
booted into an unsupported operating system, was interrupted during the
boot process, or detected an unrecoverable soware error.
Solid The controller is booting up.
Continuously
flashing
This indicates a hardware error. An internal power supply has failed. Check
front-panel I/O and adapter module connections for shorts. Remove any
shorts and power cycle the controller. If the problem persists, contact
National Instruments.
O Normal operation.
Connecting the NI-7932R to the Host Computer
Complete the following steps to connect the NI-7932R to the host computer using
the USB device port.
1. Power on the host computer.
2. Connect the NI-7932R to the host computer using the USB A-to-B cable.
Note Alternatively, you can use the RJ-45 Ethernet port to connect
the NI-7932R to the host computer.
The device driver soware automatically detects the NI-7932R. If the device
driver soware does not detect the NI-7932R, verify that you installed the
appropriate NI soware in the correct order on the host computer.
