3. Press down firmly on the chassis to compress the spring until the clip

locks in place on the DIN rail.

Caution Remove any C Series I/O modules from the chassis before removing the chassis

from the DIN rail.

Connecting the NI 9144 Chassis to a Network

NI recommends that you install a private network segment for your

deterministic Ethernet expansion devices. Slave devices cause network

flooding on a standard network. Non-EtherCAT frames jeopardize the

system performance and determinism on an EtherCAT network. Refer to

the EtherCAT Technology Group Web site at www.ethercat.org, for

more information.

The following devices are required to connect the NI 9144 chassis to a

network successfully: a host computer, a supported LabVIEW Real-Time

target1 with the NI-Industrial Communications for EtherCAT software

driver installed on it, and an NI 9144 slave device.

To have your LabVIEW target establish a connection with the NI 9144

chassis, connect the secondary port of the LabVIEW Real-Time target to

the NI 9144 IN port. Use a standard Category 5 (CAT-5) or better Ethernet

cable. Use the NI914 4 OUT port to connect to other NI 9144 chassis and

slave devices on the same segment.

Once the connection is established, install the NI-Industrial

Communications for EtherCAT software on the host computer and then use

Measurement and Automation Explorer (MAX) to install the NI-Industrial

Communications for EtherCAT driver on the target.

Caution To update your firmware on the NI 9144 chassis, refer to the Updating your

Firmware section of this user guide.

Caution To prevent data loss and to maintain the integrity of your EtherCAT installation,

do not use a CAT-5 Ethernet cable longer than 100m. 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.

Note If you are not using a LabVIEW Real-Time target as the master controller, consult

your product documentation about networking connections.

1 Supported LabVIEW targets include the NI cRIO-9074 and PXI RT with the NI PXI-8231 Ethernet interface.
