Installing Software on the Host Computer
If you do not currently have any NI software installed on your host computer, see the Install
Software section for details on required software and in which order to install it. If you have
some NI software already installed, see the Software Compatibility Resources section for
resources to check the compatibility of your software with your controller.
Install Software
Before using the cRIO-904x, you must install the following application software and device
drivers on the host computer in the order shown.
Refer to the "Choosing Your Programming Mode" section of the cRIO-904x User Manual to
determine the programming modes you wish to use.

Software Compatibility Resources
For more information about installing the correct versions of software, visit ni.com/info and
enter the Info Code swsupport.
For tips on resolving software compatibility issues with CompactRIO systems, visit ni.com/
info and enter the Info Code swcompatibility.
Note If you try to install software that already exists on your host computer, the
installer will show nothing installed.
1LabVIEW FPGA Module is not required when using Real-Time or Real-Time Scan (IO Variables)
program modes. To program the user-accessible FPGA on the cRIO-904x or deploy C Series
modules in the LabVIEW FPGA program mode, LabVIEW FPGA Module is required.
2NI CompactRIO Device Drivers 17.6 and later include NI-DAQmx driver software. To deploy
C Series modules installed in the cRIO-904x in Real-Time (NI-DAQmx) mode, ensure that NI-
DAQmx is selected during installation. To deploy C Series modules installed in the cRIO-904x in
Real-Time Scan (IO Variables) mode, ensure that NI Scan Engine is selected during installation.

1. Verify that power is not connected to the I/O connector(s) on the C Series module and the
cRIO-904x.
Note If the system is in a nonhazardous location, the cRIO-904x can be
powered on when you install modules.
2. Press the latches on the C Series module.
3. Align the C Series module with a slot and seat it in the slot until the latches lock in place.
Connecting the cRIO-904x
The cRIO-904x has the following connectors, LEDs, and buttons. For a full description of all
front panel features, see the cRIO-904x User Manual.

Connecting the Controller to Ground
You must connect the cRIO-904x grounding terminal to the grounding electrode system of the
facility.
What to Use
• Ring lug
• Wire, 1.3 mm2 (16 AWG) or larger
• Screwdriver, Phillips #2
What to Do
Complete the following steps to ground the cRIO-904x.
1. Attach the ring lug to the wire.
2. Remove the grounding screw from the grounding terminal on the cRIO-904x.
cRIO-904x Getting Started Guide | © National Instruments | 5
3. Attach the ring lug to the grounding terminal.
4. Tighten the grounding screw to 0.5 N · m (4.4 lb · in.) of torque.
5. Attach the other end of the wire to the chassis safety ground using a method that is
appropriate for your application.
Notice If you use shielded cabling to connect to a C Series module with a plastic
connector, you must attach the cable shield to the chassis grounding terminal using
1.3 mm2 (16 AWG) or larger wire. Attach a ring lug to the wire and attach the wire
to the chassis grounding terminal. Solder the other end of the wire to the cable
shield. Use shorter wire for better EMC performance.

Connecting the Controller to Power
The cRIO-904x requires a 9 V to 30 V external power supply. The cRIO-904x filters and
regulates the supplied power and provides power for the C Series modules. The cRIO-904x
has a primary power input, V1, and a secondary power input, V2.
The POWER LED on the cRIO-904x indicates which power input is in use, as shown in the
following table.
Table 1. POWER LED Indicators
LED Color LED Pattern Indication
Green Solid The cRIO-904x is powered from the V1 input.
Yellow Solid The cRIO-904x is powered from the V2 input.
— Off The cRIO-904x is off.
Notice Do not connect V1 or V2 to a DC mains supply or to any supply that
requires a connecting cable longer than 3 m (10 ft). A DC mains supply is a local
DC electricity supply network in the infrastructure of a site or building.
What to Use
• Ferrite (included in kit)
• Screwdriver, 2.54 mm (0.10 in.) flathead
• Primary power supply, 9 V to 30 V, 60 W minimum
• (Optional) Secondary power supply, 9 V to 30 V, 60 W minimum
NI recommends the power supplies listed in the following table for the cRIO-904x.

When you power on the cRIO-904x for the first time, the device boots into safe mode.
The POWER LED illuminates, the STATUS LED illuminates briefly, and then the
STATUS LED blinks twice every few seconds.
Connecting the Controller to the Host Computer
Complete the following steps to connect the cRIO-904x to the host computer using the Dual
Role USB C Port.
1. Power on the host computer.
2. Connect the cRIO-904x to the host computer using the USB-to-Type-A cable (included in
kit), inserting the USB Type-C connector into the Dual Role USB Type-C port. Connect
the other end of the USB cable (Type-A) to the host computer.
The device driver software automatically detects the cRIO-904x. Select Configure and
install software to this device.
cRIO-904x Getting Started Guide | © National Instruments | 9
If the device driver software does not detect the cRIO-904x, verify that you installed the
appropriate NI software in the correct order on the host computer as described in
Installing Software on the Host Computer.
Discovering the Controller in MAX
Complete the following steps to find the cRIO-904x controller in MAX.
1. Launch MAX on the host computer.
2. Expand Remote Systems in the configuration tree and locate your system.
3. Select your target.
Tip MAX lists the system under the model number followed by the serial
number, such as NI-cRIO-9048-01C0F8C4 by default.
