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
Ethernet cable to connect the controller to an Ethernet hub, or use an
Ethernet crossover cable to connect the controller 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 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 controller requires an external power supply that meets the
specifications in the Power Requirements section. The controller filters and
regulates the supplied power and provides power for all of the I/O modules
in the chassis. You must connect a power supply to at least one pair of
V and C terminals. Optionally, you can connect a power supply to the
other pair of V and C terminals. The controller draws power from the
power supply with the higher voltage. The controller has one layer of

reverse-voltage protection. Complete the following steps to connect power
supplies to the controller.
1. Connect the positive lead of the power supply to the V1 or V2 terminal
of the COMBICON power connector shipped with the controller, and
tighten the terminal screw. Figure 4 shows the terminal screws, which
secure the wires in the screw terminals, and the connector screws,
which secure the power connector on the controller.
Figure 4. COMBICON Power Connector
2. Connect the negative lead of the power supply to one of the C terminals
of the power connector and tighten the terminal screw.
3. Optionally, you can connect the positive lead of another power supply
to the other V terminal and the negative lead to one of the C terminals.
You must install the ferrite across both pairs of wires.
4. Install the power connector on the front panel of the controller and
tighten the connector screws.
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. The controller switches
between V1 and V2 without affecting operation.
Caution The C terminals are internally connected to each other. If you use two power
supplies, make sure that they share a common ground.
Caution The C terminals are internally connected to the controller chassis to prevent a
faulty ground connection from causing the chassis ground to float. If you reverse the input
voltage, the positive input voltage is connected directly to the chassis. The controller
has built-in reversed-voltage protection, but reversed voltage can damage connected
peripherals if the chassis ground is not reliably connected to earth ground.
Caution Do not tighten or loosen the terminal screws on the power connector while the
power connector is plugged into the controller or while the power supply is on.

Powering On the Controller
Plug in each power supply to the CompactRIO system. The controller runs
a power-on self test (POST). During the POST, the Power and Status LEDs
turn on. The Status LED turns off, indicating that the POST is complete. If
the LEDs do not behave in this way when the controller powers on, refer to
the Understanding LED Indications section.
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.
Connecting Serial Devices to the Controller
The controller 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. For more information about the Serial VIs, refer to the
LabVIEW Help.

Using the Internal Real-Time Clock
The system clock of the cRIO-9012/9014 is synchronized with the internal
high-precision real-time clock at startup. This synchronization provides
timestamp data to the controller. You can also use the internal real-time
clock to correct drift of the system clock. Refer to the Specifications section
for the accuracy specifications of the real-time clock.
Using the SMB Connector for Digital I/O
You can use the SMB connector of the cRIO-9012/9014 to connect digital
devices to the controller. For example, if you connect the pulse-per-second
output of a GPS device to the SMB connector of the cRIO-9012/9014, you
can use the GPS device to correct for drift of the system clock.
For software that supports GPS drift-correction and other digital I/O
through the SMB connector, go to ni.com/info and enter the Info Code
criosmb.
Connecting USB Mass-Storage Devices to the Controller
The cRIO-9012/9014 supports common USB mass-storage devices such as
USB Flash drives and USB-to-IDE adapters formatted with FAT16 and
FAT32 file systems. You can connect USB mass-storage devices to the
cRIO-9012/9014 while the controller is operating. USB devices are
mapped to the U: drive in LabVIEW. The cRIO-9012/9014 does not
support other types of USB devices. Refer to the LabVIEW Help for more
information.

SAFE MODE Switch
The position of the SAFE MODE switch determines whether the embedded
LabVIEW Real-Time engine launches when the controller boots. 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 when the controller boots, the controller 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 controller 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
• No flow control
The serial-port terminal program displays the IP address and firmware
version of the controller, and alerts you when you connect an unsupported
USB device to the controller. 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 of the controller to 0.0.0.0. If the controller is on your
local subnet and the IP RESET switch is in the ON position, the controller
appears in MAX with IP address 0.0.0.0. You can configure a new
IP address for the controller in MAX. Refer to the Resetting the Network
Configuration of the Controller section for more information about
resetting the IP address. You also can push this switch to the ON position
to unlock a controller that was previously locked in MAX.
