The following sections contain instructions for the mounting methods. Before using any of
these mounting methods, record the serial number from the back of the chassis. You will be
unable to read the serial number after you have mounted the chassis.
Caution Make sure that no I/O modules are in the chassis before mounting it.
Mounting the Chassis on a Panel
Panel or wall mounting is the best method for applications that are subject to high shock and
vibration. You can use the NI 9904 panel mount kit to mount the cRIO-FRC II on a flat
surface. Complete the following steps.
1. Fasten the chassis to the panel mount kit using a number 2 Phillips screwdriver and two
M4 × 25 screws. NI provides these screws with the panel mount kit. You must use these
screws because they are the correct depth and thread for the panel. Tighten the screws to a
maximum torque of 1.3 N · m (11.5 lb · in.).

the Mounting Holes
Panel or wall mounting is the best method for applications that are subject to high shock and
vibration. If you do not have the NI 9904 panel mount kit and do not require the portability
that the NI 9904 affords, you can mount the chassis directly on a flat surface using the
mounting holes. Complete the following steps.
NI cRIO-FRC II User Manual and Specifications | © National Instruments | 7

1. Align the chassis on the surface.
2. Fasten the chassis to the surface using M4 or number 8 flathead screws. NI does not
provide these screws with the chassis.
Figure 8. Mounting the Chassis Directly on a Flat Surface
Caution Make sure that no I/O modules are in the chassis before removing it
from the surface.
Mounting the Chassis on a DIN Rail
You can order the NI 9912 DIN rail mount kit if you want to mount the chassis on a DIN rail.
You need one clip for mounting the chassis on a standard 35 mm DIN rail. Complete the
following steps to mount the chassis on a DIN rail.
1. Fasten the DIN rail clip to the chassis using a number 2 Phillips screwdriver and two
M4 × 25 screws. NI provides these screws with the DIN rail mount kit. Tighten the
screws to a maximum torque of 1.3 N · m (11.5 lb · in.).

5. Repeat these steps to install additional I/O modules.
Removing I/O Modules from the Chassis
Complete the following steps to remove a C Series I/O module from the chassis.
1. Make sure that no I/O-side power is connected to the I/O module. If the system is in a
nonhazardous location, the chassis power can be on when you remove I/O modules.
2. Squeeze the latches on both sides of the module and pull the module out of the chassis.
Connecting the Chassis to Earth Ground
You must connect the panhead screw at the end of the chassis to ground as required by the
FRC Game Manual.
Connecting the Chassis to a Network
Connect the chassis 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
NI cRIO-FRC II User Manual and Specifications | © National Instruments | 11

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.
The first time you power up the chassis, it attempts to initiate a DHCP network connection. If
the chassis is unable to initiate a DHCP connection, it connects to the network with a link-
local IP address with the form 169.254.x.x. After powerup, you must install software on
the chassis and configure the network settings in NI Measurement & Automation Explorer
(MAX).
Note Installing software may change the network behavior of the chassis. For
information about network behavior by installed software version, go to ni.com/info
and enter the Info Code ipconfigcrio.
Wiring Power to the Chassis
The cRIO-FRC II requires an external power supply that meets the specifications in the Power
Requirements section. The cRIO-FRC II filters and regulates the supplied power and provides
power for all of the I/O modules. The cRIO-FRC II has one layer of reverse-voltage
protection. Complete the following steps to connect a power supply to the chassis.
1. Ensure that the power supply is turned off.
Caution Do not install or remove the power connector from the front panel of
the cRIO-FRC II while power is applied.
2. Connect the positive lead of the power supply to the V terminal of the power connector
shipped with the cRIO-FRC II, and tighten the terminal screw. The following figure
shows the terminal screws, which secure the wires in the screw terminals, and the
connector screws, which secure the power connector on the front panel.

Powering On the cRIO-FRC II
When you apply power to the cRIO-FRC II, 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.
You can configure the cRIO-FRC II to launch an embedded stand-alone LabVIEW RT
application each time you boot the controller. Refer to the LabVIEW Robotics Programming
Guide for the FIRST Robotics Competition for more information.
Restarting the cRIO-FRC II Using the Reset Button
Pressing the Reset button restarts the controller. The FPGA continues to run unless you have
selected the Autoload VI on device reboot chassis reset option.
To restart the cRIO-FRC II in safe mode, press and hold the Reset button for 5 s, then release
it. The Status LED lights solid yellow, indicating that the cRIO-FRC II is in safe mode. Refer
to the MAX help for information about safe mode.
Controller Startup Options
You can configure the following controller startup options in MAX:
• Safe Mode
• Console Out
• IP Reset
• No App
• No FPGA App
To turn these startup options on or off, select the controller under Remote Systems in the
MAX configuration tree, then select the Controller Settings tab. Refer to the MAX help for
information about the startup options and how to configure the controller.
Chassis Reset Options
The following table lists the reset options available on CompactRIO systems such as the
cRIO-FRC II. These options determine how the chassis behaves when the controller is reset in
various conditions. Use the RIO Device Setup utility to select reset options. Access the RIO
Device Setup utility by selecting Start»All Programs»National Instruments»NI-RIO»RIO
Device Setup.

Connecting Serial Devices to the cRIO-FRC II
The cRIO-FRC II 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
RT application. For more information about the Serial VIs, refer to the LabVIEW Help.

about programming this LED.
Using the System Clock to Provide Data
Timestamps
At startup, the system clock resets to January 1, 1970, 12:00 a.m. (midnight). For information
about synchronizing the system clock with an SNTP time server on the network at startup, go
to ni.com/info and enter the Info Code criosntp.
Troubleshooting Network Communication
If the cRIO-FRC II cannot communicate with the network, you can perform the following
troubleshooting steps.
1. Press and hold the Reset button for 5 s, then release it. The chassis is now in safe mode
with output from the serial port enabled. You can use a serial port terminal to read the IP
address of the controller. If you want the controller to attempt a new DHCP connection,
proceed to step 2.
2. Press and hold the Reset button for 5 s, then release it. The cRIO-FRC II attempts to
establish a new DHCP connection. If it fails, it assigns itself a link-local IP address. If the
DHCP connection is successful and appropriate for your application, skip to step 4.
3. Configure the IP and other network settings in MAX.
4. Press and release the Reset button to reboot the chassis.
cRIO-FRCII Specifications
The following specifications are typical for the -0 °C to 55 °C operating temperature range
unless otherwise noted.
Caution Do not operate the cRIO-FRC II in a manner not specified in this
document. Product misuse can result in a hazard. You can compromise the safety
