Table 1. IP Enclosure Options
Overview
The NI 9921 and NI 9922 enclosures for NI Wi-Fi data acquisition (DAQ)
devices provide a minimum of IP 54 protection from harsh outdoor and
industrial environments. The two-digit ingress protection (IP) rating is
defined by the IEC 60529 standard and specifies the degree to which the
enclosures protect against the intrusion of solid particles (represented
by the first digit) and water (represented by the second digit). Refer to
Table 2 for a complete list of IP ratings and their meanings.
An IP 54 rating prevents entry by dust particles and spraying water.
The low-cost NI 9921 enclosure features rubberized glands for passing
I/O signals through to a WLS-9xxx device mounted inside and an external
antenna for communication to a host PC. The NI 9922 enclosure features
an additional Ethernet port and a four-pin trigger connector, all sealable
against the environment.
Using IP Enclosures with NI Wi-Fi
DAQ Devices
Each NI 9921 and NI 9922 can house one WLS-9xxx wireless DAQ device.
Cables inside each enclosure connect power, Ethernet, antenna, trigger,
and I/O lines to IP-rated connectors. With proper installation, the
enclosures provide a minimum of IP 54 protection.
Each enclosure kit also includes mating connectors for creating your
own IP-rated cables. In addition to the NI 9921, the contents of the
NI 9921 shipping kit include:
• M12 female mating connector kit (power connector)
• Two M25 cable gland clamps
• Four cable glands (two split, two blanking) for I/O
• 2.4 GHz antenna
• WLS-9xxx DIN rail mounting kit
The NI 9922 shipping kit contains the same items as the NI 9921 kit
as well as the following:
• Ethernet field termination kit
• M12 male mating connector kit (trigger connector)
Cabling and Accessories
As an alternative to the included field-terminable connector kits, you
may purchase sealed, IP-rated cable assemblies to ensure proper ingress
protection. Additional cable gland sizes are also available. Refer to the
ordering information for part numbers.

System Assurance Programs
NI system assurance programs are designed to make it even easier for you to
own an NI system. These programs include configuration and deployment
services for your NI PXI, CompactRIO, or Compact FieldPoint system. The
NI Basic System Assurance Program provides a simple integration test and
ensures that your system is delivered completely assembled in one box.
When you configure your system with the NI Standard System Assurance
Program, you can select from available NI system driver sets and application
development environments to create customized, reorderable software
configurations. Your system arrives fully assembled and tested in one box with
your software preinstalled. When you order your system with the standard
program, you also receive system-specific documentation including a bill of
materials, an integration test report, a recommended maintenance plan, and
frequently asked question documents. Finally, the standard program reduces
the total cost of owning an NI system by providing three years of warranty
coverage and calibration service. Use the online product advisors at
ni.com/advisor to find a system assurance program to meet your needs.
