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

Indoor use only.
Note Refer to the NI-7932R Specifications at ni.com/manuals for complete
specifications.
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.
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 off.
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. 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.
After you install software 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 off 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 software installed, which is the out-of-box state, or the
controller has detected an error in its software.
An error can occur when an attempt to upgrade the software is
interrupted. Refer to the MAX Help for information about reinstalling
software on the controller.
3 flashes every few
seconds
The controller is in safe mode. Refer to the MAX Help for
information about safe mode.
NI-7932R Getting Started Guide | © National Instruments | 7

LED State Indication
4 flashes every few
seconds
The software 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
software 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.
Off 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 software automatically detects the NI-7932R. If the device driver
software does not detect the NI-7932R, verify that you installed the appropriate NI
software in the correct order on the host computer.
Tip You can also use the Ethernet port to connect directly to the host computer or
network. Refer to the user manual on ni.com/manuals for more information about
Ethernet connections.

Why Can't the NI-7932R Communicate with the
Network?
1. Connect cables from your device to the host computer.
a) If you are using the USB port, use a USB cable to connect the NI-7932R USB
device port to a host computer.
The USB driver creates a virtual network interface and assigns an IP address to the
NI-7932R in the format of 172.22.11.x.
b) If you are using the ethernet port, use an ethernet to connect the ethernet port to the
host computer.
2. In MAX, expand your system under Remote Systems.
3. Select the Network Settings tab to configure the IP and other network settings.
4. (Optional) Use the RJ-45 Ethernet port 1 to reconnect the NI-7932R to the host computer.
The NI-7932R attempts to initiate a DHCP network connection at powerup.
If the NI-7932R cannot contain an IP address, it connects to the network with a link-local
IP address with the form 169.254.x.x. The host computer communicates with the
NI-7932R over a standard Ethernet connection.
Why Doesn't the Device Appear in MAX?
If you cannot find the NI-7932R in MAX, complete the following steps.
• Ensure you have the correct version of FlexRIO Support installed on the host computer.
• Check the USB cable connections at the NI-7932R and host computer. Check the
Ethernet cable connections at the host computer and router.
• If you have network firewalls or other security software enabled, try temporarily turning
them off. You may also need to add an exception for MAX. In Windows 7, select Start»
Control Panel»System and Security»Windows Firewall»Allow a program through
Windows Firewall. Click Allow another program, select Measurement &
Automation, click Add, then click OK.
• Ensure that UDP port 44525 is open to communication on the host computer. If you are
using an intelligent switch on the network, ensure that it is not disabling UDP port 44525.
• Hold down the RESET button for 5 seconds to reboot the target into safe mode. This
prevents a real-time app from running. Sometimes a malfunctioning real-time app
prevents network communication.
• Check the Device Manager to ensure the National Instruments USBLAN adapter is
recognized. In Windows 7, select Start»Control Panel»Device Manager»Network
adapters»National Instruments»USBLAN adapter. If the USBLAN adapter is not
recognized, you must reinstall FlexRIO Support.
• Ensure that the Ethernet cable is connected correctly.
