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. 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.

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, nonconductive pollution becomes conductive because of 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 Category 1:
Measurement circuits are subjected to working voltages2 and 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 occur in electrical distribution systems. The following is a description of Measurement (Installation3) Categories:

• Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS4 voltage. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, 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.

1. Measurement Categories as defined in electrical safety standard IEC 61010-1.
2. Working voltage is the highest rms value of an AC or DC voltage that can occur across any particular insulation.
3. Measurement Category is also referred to as Installation Category.
4. 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.

Unpacking

The NI 8255R 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:

1. Ground yourself using a grounding strap or by touching a grounded object, such as the computer chassis.

2. 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.

3. Remove the device from the package and inspect it for loose components or any other signs of damage. Notify National Instruments if the device appears damaged in any way. Do not install a damaged device in the computer.

Store the NI 8255R in the antistatic package when not in use.

Installation

The following instructions are for general installation. Refer to the documentation provided by your computer manufacturer for specific instructions and warnings. Refer to the Specifications section for a list of the typical power requirements for the NI 8255R.

1. Install NI Vision Acquisition Software before installing the NI 8255R. Refer to the NI Vision Acquisition Software Release Notes for specific installation instructions.

2. Power off and unplug the computer.
   Caution To protect yourself and the computer from electrical hazards, the computer must remain unplugged until the installation is complete.

3. Remove the computer cover to expose the expansion slots.
   Caution Installing a PCIe device into a PCI, PCI-X, AGP, or any non-PCIe slot can damage both the computer motherboard and the device. If you are unsure of the difference between connector types, do not install the device. Refer to the documentation provided by your computer manufacturer to determine the correct slot in which to install the NI 8255R.

4. Touch a metal part of the computer to discharge any static electricity that might be on your clothes or body. Static electricity can damage the device.

5. Choose an unused x1 or larger PCIe slot, and remove the corresponding expansion slot cover on the back panel of the computer. Figure 1 shows the different types of expansion slots available on most computers.
   Note
   The NI 8255R is intended for a x1 PCIe slot. The NI 8255R will fit into, and can be used in a x4, x8, or x16 PCIe slot.

Wiring Isolated Output Power to the NI 8255R
Complete the following steps to connect power for the isolated outputs to the NI 8255R.

Caution
Do not connect the NI 8255R isolated power to a source less than 5 VDC or greater than 30 VDC. Doing so could damage the device.

1. Complete this step if you are using the NI desktop power supply (part number 778794-01). If you are using a power supply other than the NI desktop power supply skip this step and proceed to step 2.

   • Disconnect the 4-position power connector from the power supply, as shown in Figure 3.

   3. C Position
   4. Power Supply Wire
      Figure 3. Removing the 4-Position Power Connector from the Power Supply
   • Depending on your connection method, reconnect the Viso and Ciso wires to one of the following options:
   • Viso and Ciso on the 44-pin D-SUB
   • Viso and Ciso on the DIN rail terminal block
   • Viso and Ciso on the NI Vision I/O Terminal Block and Prototyping Accessory
     Refer to Table 1 for a summary of the isolated power supply connections.
     Table 1. Isolated Power Supply Connection Options

2. Complete this step if you are using a power supply other than the NI desktop power supply. If you are using the NI desktop power supply, skip this step and proceed to step 3.

• Wire the voltage output and the common-mode (ground) output of the isolated power supply to one of the following options:
• Viso and Ciso on the 37-pin terminal block
• Viso and Ciso on the 44-pin D-SUB
• Viso and Ciso on the NI Vision I/O Terminal Block and Prototyping Accessory
  Refer to Table 1 for a summary of the isolated power supply connections.

3. (Optional) To suppress electromagnetic interference, install a ferrite on the power supply cable as close to the connection to the NI 8255R as possible. Wrap the power supply cable around the ferrite two times, as shown in Figures 4 and 5.
