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 need to build your own cable, refer to the
Cabling
section for more information about
Ethernet cable wiring connections.
The first time you power up the chassis, the BIOS network settings determine the initial IP
settings and other network behavior. 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
and enter the Info Code
ipconfigcrio
.
The BIOS network settings of the cRIO-9072/9073/9074 depend on the part number of the
chassis. The part number is located on the bottom of the chassis.
BIOS Network Settings of cRIO-9072/9073/9074 with
Part Number Beginning 192172
If the part number of the cRIO-9072/9073/9074 begins with 192172, the IP address, subnet
mask, DNS address, gateway, and Time Server IP are all set to
0.0.0.0
at powerup.
The host computer communicates with the chassis over a standard Ethernet connection. If the
host computer is on a network, you must configure the chassis on the same subnet as the host
computer. If neither the host computer nor the chassis is connected to a network, you can
connect the two directly using a crossover cable.
If you want to use the chassis on a subnet other than the one the host computer is on, first
connect the chassis 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.
BIOS Network Settings of cRIO-9072/9073/9074 with
Part Number Beginning 198944
If the part number of the cRIO-9072/9073/9074 begins with 198944, the chassis attempts to
initiate a DHCP network connection at powerup. 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
.
The host computer communicates with the chassis over a standard Ethernet connection. If
neither the host computer nor the chassis is connected to a network, you can connect the two
directly using a crossover cable.
Connecting the Chassis to Earth Ground
You must connect the chassis grounding screw to earth ground. Complete the following steps
to connect to earth ground.
1.
Attach a ring lug to a 1.6 mm
2
(14 AWG) or larger wire.
