Configuring the NI 9149
You can connect the NI 9149 to a host computer or network and configure the startup options
using the USB device port or the RJ-45 Gigabit Ethernet port 1.
Tip Refer to the getting started guide on ni.com/manuals for basic configuration
instructions and information about connecting to a host computer using the USB
device port. NI recommends using the USB device port for configuration, debug,
and maintenance.
Connecting the NI 9149 to the Host Computer or
Network Using Ethernet
Complete the following steps to connect the NI 9149 to a host computer or Ethernet network
using the RJ-45 Gigabit Ethernet port 1. NI recommends using the RJ-45 Gigabit Ethernet port
1 for communication with deployed systems.
1. Power on the host computer or Ethernet hub.
2. Connect the RJ-45 Gigabit Ethernet port 1 on the NI 9149 to the host computer or
Ethernet hub using a standard Category 5 (CAT-5) or better shielded, twisted-pair
Ethernet cable.
Caution To prevent data loss and to maintain the integrity of your Ethernet
installation, do not use a cable longer than 100 m (328 ft).
The NI 9149 attempts to initiate a DHCP network connection the first time you connect
using Ethernet. The NI 9149 connects to the network with a link-local IP address with the
form 169.254.x.x if it is unable to initiate a DHCP connection.
Finding the NI 9149 on the Network (DHCP)
Complete the following steps to find the NI 9149 on a network using DHCP.
1. Disable secondary network interfaces on the host computer, such as a wireless access
card on a laptop.
2. Ensure that any anti-virus and firewall software running on the host computer allows
connections to the host computer.
Note MAX uses UDP 44525. Refer to the documentation of your firewall
software for information about configuring the firewall to allow communication
through the UDP 44525.
3. Launch MAX on the host computer.
2| ni.com | NI 9149 User Manual

4. Expand Remote Systems in the configuration tree and locate your system.
Tip MAX lists the system under the model number followed by the serial
number, such as NI-CRIO-9149-1856AAA.
Configuring Startup Options
Complete the following steps to configure the NI 9149 startup options in MAX.
1. In MAX, expand your system under Remote Systems.
2. Select the Startup Settings tab to configure the startup settings.
NI 9149 Startup Options
You can configure the following NI 9149 startup options.
Table 1. NI 9149 Startup Options
Startup Option Description
Force Safe
Mode
Rebooting the NI 9149 with this setting on starts the NI 9149 without
launching LabVIEW Real-Time or any startup applications. In safe mode,
the NI 9149 launches only the services necessary for updating
configuration and installing software.
Disable FPGA
Startup App
Rebooting the NI 9149 with this setting on prevents autoloading of any
FPGA application.
Note When you reset the cRIO-906x controller either
programmatically or by using the RESET button, you also reset
the FPGA. All FPGA I/O lines are tri-stated after a reset, and
will enter predefined states once loaded.
Enable Secure
Shell (SSH)
Logins
Rebooting the NI 9149 with this setting on starts sshd on the NI 9149.
Starting sshd enables logins over SSH, an encrypted communication
protocol.
Note Visit ni.com/info and enter the Info Code openssh for
more information about SSH.

USB Device Port
The NI 9149 USB device port is intended for device configuration, application deployment,
debugging, and maintenance. For example, you can use the USB device port to install software
or driver updates during field maintenance instead of interrupting communication on the RJ-45
Ethernet ports.
Caution Do not hot-swap USB devices while the NI 9149 is in a hazardous
location or connected to high voltages. If the NI 9149 is not in a hazardous location,
you can connect and disconnect USB devices without affecting operation.

Chassis Grounding Screw
The NI 9149 provides a chassis grounding screw.
Figure 5. NI 9149 Chassis Grounding Screw

1. Chassis grounding screw
For EMC compliance, you must connect the NI 9149 to earth ground through the chassis
ground screw. Use wire that is 1.31 mm2 (16 AWG) solid copper wire with a maximum length
of 1.5 m (5 ft). Attach the wire to the earth ground of the electrode system of the facility.
10 | ni.com | NI 9149 User Manual

Caution 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
1.31 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.
For more information about ground connections, visit ni.com/info and enter the Info Code
emcground.
Internal Real-Time Clock
The NI 9149 contains an internal real-time clock that maintains system time when the NI 9149
is powered off. The system clock of the NI 9149 is synchronized with the internal real-time
clock at startup. You can set the real-time clock using MAX, or you can set the clock
programmatically using LabVIEW.
Refer to the specifications on ni.com/manuals for the real-time clock accuracy specifications.
Battery
The NI 9149 contains a lithium cell battery that stores the system clock information when the
NI 9149 is powered off. There is only a slight drain on the battery when power is applied to
the NI 9149 power connector. The rate at which the battery drains when power is disconnected
depends on the ambient storage temperature. For longer battery life, store the NI 9149 at a
cooler temperature and apply power to the power connector. Refer to the specifications on
ni.com/manuals for the expected battery lifetime.
The battery is not user-replaceable. If you need to replace the battery, contact NI. Refer to the
specifications on ni.com/manuals for information about battery disposal.
Mounting the Device
To obtain the maximum allowable ambient temperature of 70 °C, you must mount the NI 9149
horizontally on a flat, metallic, vertical surface such as a panel or wall. You can mount the
NI 9149 directly to the surface or use the NI Panel Mounting Kit. The following figure shows
the NI 9149 mounted horizontally.
Figure 6. NI 9149 Horizontal Mounting

1. Up
You can also mount the NI 9149 in other orientations, on a nonmetallic surface, on a 35-mm
DIN rail, on a desktop, or in a rack. Mounting the NI 9149 in these or other configurations can
NI 9149 User Manual | © National Instruments | 11

reduce the maximum allowable ambient temperature and can affect the typical accuracy of
modules in the NI 9149. For more information about typical accuracy specifications for
C Series modules and temperature deratings caused by different mounting configurations, visit
ni.com/info and enter the Info Code criotypical.
Caution Make sure that no C Series modules are in the NI 9149 before mounting
it.
Tip Before using any of these mounting methods, record the serial number from
the back of the NI 9149 so that you can identify the NI 9149 in MAX. You will be
unable to read the serial number after you mount the NI 9149.
