Safety Information
Caution The following paragraphs contain important safety information you must follow
when installing and operating the device.
Do not operate the device in a manner not specified in the documentation.
Misuse of the device may result in a hazard and may compromise the safety
protection built into the device. If the device is damaged, turn it off and do
not use it until service-trained personnel can check its safety. If necessary,
return the device to National Instruments for repair.
Keep away from live circuits. Do not remove equipment covers or shields
unless you are trained to do so. If signal wires are connected to the device,
hazardous voltages can exist even when the equipment is turned off. To
avoid a shock hazard, do not perform procedures involving cover or shield
removal unless you are qualified to do so. Disconnect all field power prior
to removing covers or shields.
1 When using this accessory with the NI 8254R, three of the digital I/O signals on the device are not accessible. Refer to the
Connectors topic in the NI 8254R Help for more information.

If the device is rated for use with hazardous voltages (>30 Vrms, 42.4 Vpk,
or 60 Vdc), it may require a safety earth-ground connection wire. Refer to
the device specifications for maximum voltage ratings.
Because of the danger of introducing additional hazards, do not install
unauthorized parts or modify the device. Use the device only with the
chassis, modules, accessories, and cables specified in the installation
instructions. All covers and filler panels must be installed while operating
the device.
Do not operate the device in an explosive atmosphere or where flammable
gases or fumes may be present. Operate the device only at or below the
pollution degree stated in the specifications. Pollution consists of any
foreign matter—solid, liquid, or gas—that may reduce dielectric strength
or surface resistivity. The following is a description of pollution degrees.
• Pollution Degree 1—No pollution or only dry, nonconductive
pollution occurs. The pollution has no effect.
• Pollution Degree 2—Normally only nonconductive pollution occurs.
Occasionally,nonconductivepollutionbecomes conductivebecauseof
condensation.
• Pollution Degree 3—Conductive pollution or dry, nonconductive
pollution occurs. Nonconductive pollution becomes conductive
because of condensation.
Clean the device and accessories by brushing off light dust with a soft,
nonmetallic brush. Remove other contaminants with a stiff, nonmetallic
brush. The unit must be completely dry and free from contaminants before
returning it to service.
You must insulate signal connections for the maximum voltage for which
the device is rated. Do not exceed the maximum ratings for the device.
Remove power from signal lines before connection to or disconnection
from the device.
Caution National Instruments measurement products may be classified as either
Measurement Category I or II. Operate products at or below the Measurement Category
level specified in the hardware specifications.
Measurement Category1: Measurement circuits are subjected to working
voltages2and transient stresses (overvoltage) from the circuit to which they
are connected during measurement or test. Measurement Category
establishes standardized impulse withstand voltage levels that commonly

2 Working voltage is the highest rms value of an AC or DC voltage that can occur across any particular insulation.

occur in electrical distribution systems. The following is a description of
Measurement (Installation1) Categories:
• Measurement Category I is for measurements performed on circuits
not directly connected to the electrical distribution system referred to
as MAINS2voltage. This category is for measurements of voltages
from specially protected secondary circuits. Such voltage
measurementsincludesignallevels, special equipment,limited-energy
parts of equipment, circuits powered by regulated low-voltage sources,
and electronics.
• Measurement Category II is for measurements performed on circuits
directly connected to the electrical distribution system. This category
refers to local-level electrical distribution, such as that provided by a
standard wall outlet (e.g., 115 V for U.S. or 230 V for Europe).
Examples of Measurement Category II are measurements performed
on household appliances, portable tools, and similar products.
• Measurement Category III is for measurements performed in the
building installation at the distribution level. This category refers to
measurements on hard-wired equipment such as equipment in fixed
installations, distribution boards, and circuit breakers. Other examples
are wiring, including cables, bus-bars, junction boxes, switches,
socket-outlets in the fixed installation, and stationary motors with
permanent connections to fixed installations.
• Measurement Category IV is for measurements performed at the
primary electrical supply installation (<1,000 V). Examples include
electricity meters and measurements on primary overcurrent
protection devices and on ripple control units.
Unpacking
The NI 8254R ships in an antistatic package to prevent electrostatic
discharge from damaging device components. To avoid such damage in
handling the device, take the following precautions:
• Ground yourself using a grounding strap or by holding a grounded
object, such as the computer chassis.
• Touch the antistatic package to a metal part of the computer chassis
before removing the device from the package.
Caution Never touch the exposed pins of connectors.
1 Measurement Category is also referred to as Installation Category.
2 MAINS is defined as the (hazardous live) electrical supply system to which equipment is designed to be connected for the
purpose of powering the equipment. Suitably rated measuring circuits may be connected to the MAINS for measuring
purposes.

Caution Do not connect the NI 8254R isolated power to a source less than 5 VDC or
greater than 30 VDC. Doing so could damage the NI 8254R.
The NI 8254R ships with a 2-position power connector that plugs directly
into the isolated outputs power input connector on the NI 8254R. To wire
power to the 2-position connector, complete the following steps:
1. Wire the voltage output of the isolated power supply to the isolated
outputs power input, labeled V, on the 2-position connector.
2. Wire the common-mode signal (ground) output of the power supply
to the isolated outputs common-mode signal input, labeled C, on the
2-position connector.
Configuring the NI 8254R
After you have installed the NI 8254R and powered on your computer,
Windows will recognize the device and assign resources to it. Use
Measurement & Automation Explorer (MAX), the National Instruments
configuration utility, to configure the IEEE 1394 camera connected to the
NI 8254R for acquisition.
Note You must install NI Vision Acquisition Software 8.0 or later before configuring your
camera in MAX. Refer to the NI Vision Acquisition Release Notes for information about
configuring your camera.
