Connecting the NI 9144 to an NI Master Controller
Before you connect the NI 9144 to an NI master controller, you must setup and connect the NI
master controller to a network. Refer to your master controller documentation on ni.com/
manuals for setup information.
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.
What to Use
• NI 9144
• NI Master Controller2
• Category 5 Ethernet Cable
Note To prevent data loss and to maintain the integrity of your EtherCAT
installation, do not use a CAT-5 Ethernet cable longer than 100 m. NI
recommends using a CAT-5 or better shielded twisted-pair Ethernet cable
What to Do
Connect the NI 9144 to the NI master controller as shown in the following figure.
