3. Slide the controller onto the controller slot on the chassis. Press firmly to ensure the
chassis connector and the controller connector are mated.
4. Using a number 2 Phillips screwdriver, tighten the two captive screws on the front of the
controller to 1.3 N · m (11.5 lb · in.) of torque.
Connecting the Controller to a Network
Connect the controller to an Ethernet network using the RJ-45 Ethernet port on the controller
front panel. Use a standard Category 5 (CAT-5) or better shielded, twisted-pair Ethernet cable
to connect the chassis to an Ethernet hub, or use an Ethernet crossover cable to connect the
chassis directly to a computer.
Caution To prevent data loss and to maintain the integrity of your Ethernet
installation, do not use a cable longer than 100 m. If you are using 100 Mbps
Ethernet, National Instruments recommends using a CAT-5 or better shielded
twisted-pair Ethernet cable.
If you need to build your own cable, refer to the Cabling section for more information about
Ethernet cable wiring connections.
The host computer communicates with the controller over a standard Ethernet connection. If
the host computer is on a network, you must configure the controller on the same subnet as the
NI cRIO-9002/9004 User Manual and Specifications | © National Instruments | 5

host computer. If neither the host computer nor the CompactRIO controller is connected to a
network, you can connect the two directly using a crossover cable.
If you want to use the controller on a subnet other than the one the host computer is on, first
connect the controller on the same subnet as the host computer. Use DHCP to assign an IP
address or reassign a static IP address for the subnet where you want it to be and physically
move it to the other subnet. The first time you configure the controller, you must also install
software on it. Refer to the Measurement & Automation Explorer Help for more information
about configuring the controller in Measurement & Automation Explorer (MAX). Contact
your network administrator if you need assistance configuring the host computer and
controller on the same subnet.
Wiring Power to the Controller
Caution You must install the controller on a CompactRIO chassis and tighten the
captive screws before you apply power to the controller. Installing the controller
while power is applied to it can cause damage to the chassis.
The cRIO-9002/9004 requires an external power supply that meets the specifications in the
Power Requirements section. The cRIO-9002/9004 filters and regulates the supplied power
and provides power for all of the I/O modules in the chassis. You can connect two power
sources to the cRIO-9002/9004. The cRIO-9002/9004 draws power from the power source
with the higher voltage. The cRIO-9002/9004 has one layer of reversed-voltage protection.
The power source you connect to the cRIO-9002/9004 must provide an additional layer of
reversed-current flow protection. Complete the following steps to connect power sources to
the cRIO-9002/9004.
1. Install a ferrite across the negative and positive wires for both the V1 and V2 terminals.

2. Connect the positive lead of one of the power sources to the V1 terminal and the negative
lead to one of the C terminals.
3. Connect the positive lead of the other power source to the V2 terminal and the negative
lead to one of the C terminals.
Note The controller draws power from either V1 or V2 depending on which
terminal has a higher voltage. It does not draw power from both terminals.
Caution The C terminals are internally connected to each other. Make sure to
use two power sources that have a common ground.
Powering On the cRIO-9002/9004
Plug in each power supply to the CompactRIO system. The controller runs a power-on self test
(POST). During the POST, the Power, Status, and User1 LEDs turn on. The User1 and Status
LEDs turn off, indicating that the POST is complete.
Boot Options
You can configure the controller to launch an embedded stand-alone application each time you
boot the controller. Refer to the LabVIEW Help for more information.
The following table lists the reset options available on CompactRIO backplanes, such as the
cRIO-910x devices. Use these options to determine how the CompactRIO controllers, such as
the cRIO-9002/9004 controllers, are reset in various conditions.

you reboot the controller either with or without cycling
power.
Connecting Serial Devices to the
cRIO-9002/9004
The cRIO-9002/9004 has an RS-232 serial port to which you can connect devices such as
displays or input devices. Use the Serial VIs to read from and write to the serial port from a
LabVIEW Real-Time application. For more information about the Serial VIs, refer to the
LabVIEW Help.

NO APP
USER1
ON OFF
All of the DIP switches are in the OFF position when the chassis is shipped from National
Instruments.
SAFE MODE Switch
The position of the SAFE MODE switch determines whether the embedded LabVIEW Real-
Time engine launches at startup. If the switch is in the OFF position, the LabVIEW Real-Time
engine launches. Keep this switch in the OFF position during normal operation. If the switch is
in the ON position at startup, the cRIO-9002/9004 launches only the essential services
required for updating its configuration and installing software. The LabVIEW Real-Time
engine does not launch.
If the software on the controller is corrupted, you must put the controller into safe mode and
reformat the controller drive. You can put the controller into safe mode by powering it up
either with the SAFE MODE switch in the ON position or with no software installed on the
drive. Refer to the Measurement & Automation Explorer Help for more information about
installing software on a controller and reformatting the drive on the controller.
CONSOLE OUT Switch
With a serial-port terminal program, you can use the CONSOLE OUT switch to read the IP
address and firmware version of the controller. Use a null-modem cable to connect the serial
port on the chassis to a computer. Push the switch to the ON position. Make sure that the
serial-port terminal program is configured to the following settings:
• 9,600 bits per second
• Eight data bits
• No parity
• One stop bit
The serial-port terminal program displays the IP address and firmware version. Keep this
switch in the OFF position during normal operation.
IP RESET Switch
Push the IP RESET switch to the ON position and reboot the controller to reset the IP address
and other TCP/IP settings of the controller to the factory defaults. Refer to the Troubleshooting
Network Communication section for more information about resetting the IP address. You also
NI cRIO-9002/9004 User Manual and Specifications | © National Instruments | 9

can push this switch to the ON position to unlock a chassis that was previously locked in
MAX.
NO APP Switch
Push the NO APP switch to the ON position to prevent a LabVIEW Real-Time startup
application from running at startup. If you want to permanently disable a LabVIEW Real-Time
application from running at startup, you must disable it in LabVIEW. To run an application at
startup, push the NO APP switch to the OFF position, create an application using the
LabVIEW Application Builder, and configure the application in LabVIEW to launch at
startup. If you already have an application configured to launch at startup and you push the
NO APP switch from ON to OFF, the startup application is automatically enabled. For more
information about automatically launching VIs at startup and disabling VIs from launching at
startup, refer to the LabVIEW Help.
USER1 Switch
You can define the USER1 switch for your application. To define the purpose of this switch in
your embedded application, use the RT Read Switch VI in your LabVIEW Real-Time
embedded VI. For more information about the RT Read Switch VI, refer to the LabVIEW
Help.
