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

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 soware media or online at ni.com/updates.

1 LabVIEW 2015, FlexRIO Support 2015, LabVIEW Real-Time 2015, and LabVIEW FPGA

2015 are the earliest versions of soware 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.

NI-7932

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.

NI-7932

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.

1. Positive terminal

2. Negative terminal

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.

Aer you install soware 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 soware installed, which is the out-of-box state, or the controller

has detected an error in its soware.

An error can occur when an attempt to upgrade the soware is interrupted.

Refer to the MAX Help for information about reinstalling soware on the

controller.

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 soware 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 soware 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 soware automatically detects the NI-7932R. If the device

driver soware does not detect the NI-7932R, verify that you installed the

appropriate NI soware in the correct order on the host computer.
