Introduction
This document describes how to connect the NI 9144 chassis to a network,
how to use the NI 9144 chassis features, and contains the NI 9144 chassis
specifications. The NI 9144 is a slave device and requires a compliant
EtherCAT Master and network to function.

Safety Guidelines
Operate the NI 9144 chassis only as described in this user guide.
Safety Guidelines for Hazardous Locations
The NI 9144 chassis is suitable for use in Class I, Division 2, Groups A, B,
C, D, T4 hazardous locations; Class 1, Zone 2, AEx nA IIC T4 and Ex nA
IIC T4 hazardous locations; and nonhazardous locations only. Follow these
guidelines if you are installing the NI 9144 chassis in a potentially
explosive environment. Not following these guidelines may result in
serious injury or death.
Caution Do not disconnect the power supply wires and connectors from the chassis unless
power has been switched off.

Caution Substitution of components may impair suitability for Class I, Division 2.
Caution For Zone 2 applications, install the system in an enclosure rated to at least IP 54
as defined by IEC 60529 and EN 60529.
Special Conditions for Hazardous Locations Use
in Europe
This equipment has been evaluated as Ex nA IIC T4 equipment under
DEMKO Certificate No. 07 ATEX 0626664X. Each chassis is marked
II 3G and is suitable for use in Zone 2 hazardous locations, in ambient
temperatures of –40 ≤Ta ≤ 70 °C.
Special Conditions for Marine Applications
Some chassis are Lloyd’s Register (LR) Type Approved for marine
applications. To verify Lloyd’s Register certification, visit ni.com/
certification and search for the LR certificate, or look for the Lloyd’s
Register mark on the chassis.
Mounting the NI 9144 Chassis
You can mount the chassis in any orientation on a 35 mm DIN rail or on a
panel. Use the DIN rail mounting method if you already have a DIN rail
configuration or if you need to be able to quickly remove the chassis. Use
the panel mount method for high shock and vibration applications.
Caution Your installation must meet the following requirements for space and cabling
clearance:
• Allow 25.4 mm (1 in.) on the top and the bottom of the chassis for air circulation.
• Allow 50.8 mm (2 in.) in front of C Series I/O modules for cabling clearance for
common connectors, such as the 10-terminal, detachable screw terminal connector, as
shown in Figure 2.

The following sections contain mounting method instructions. Before
using any of these mounting methods, record the serial number from the
back of the chassis. After the chassis is mounted, you will not be able to
read the serial number.
Caution Remove any C Series I/O modules from the chassis before mounting it.
Mounting the NI 9144 Chassis on a Panel
Use the NI 9905 panel mount kit to mount the NI 9144 chassis on a flat
surface. To use the NI 9905 panel mount kit, complete the following steps:
1. Fasten the chassis to the panel mount kit using a number 2 Phillips
screwdriver and two M4 ×16 screws. National Instruments provides
these screws with the panel mount kit. You must use these screws
because they are the correct depth and thread for the panel.

Mounting the Chassis on a DIN Rail
Use the NI 9915 DIN rail mount kit if you want to mount the chassis on a
DIN rail. You need one clip for mounting the chassis on a standard 35 mm
DIN rail. Complete the following steps to mount the chassis on a DIN rail:
1. Fasten the DIN rail clip to the chassis using a number 2 Phillips
screwdriver and two M4 ×16 screws. National Instruments provides
these screws with the DIN rail mount kit.
Figure 7. Installing the DIN Rail Clip on the NI 9144 Chassis
2. Insert one edge of the DIN rail into the deeper opening of the DIN rail
clip, as shown in Figure 8.

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
target1with 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 NI 9144 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 100 m. 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.
