Compliance

FCC/Canada Radio Frequency Interference Compliance*

Determining FCC Class

The Federal Communications Commission (FCC) has rules to protect wireless communications from interference.
The FCC places digital electronics into two classes. These classes are known as Class A (for use in industrial­commercial locations o nly ) or Cl ass B (for use in residential or comme rc ia l locations). Depending on whe re it is
operated, this product could be sub je ct to re strictions in the FCC rules. (In Canada, the Depa rt me nt of
Communications (DOC), of Industry Canada, regulates wireless interference in much the same way.)

Digital electronics emi t weak signals during normal op era t ion that can affect radio, television, or other wireless
products. By examining the product you purchased, you can determine the FCC Class and therefore which of the two
FCC/DOC Warnings app ly in the fol lowing sections. (Some produc t s ma y not be la be lled at all for FCC, if so the
reader should then assume these are Class A devices.)

FCC Class A products only display a simple warning statement of one paragraph in length regarding interference and
undesired operation. Most of our products are FCC Class A. The FCC rules have restrictions regarding the locations
where FCC Class A products can be ope rated.

FCC Class B products display either a FCC ID code, starting with the let te rs
or the FCC Class B co mpliance mark that appears as show n he re on the right.

The curious reader can consult the FCC web site
information.

PXI-1025 Backplane Overview

Interoperability with CompactPCI

The PXI-1025 MegaPAC backplan e is intero perable with P XI-compat ible
products and standard Compact PCI pro ducts. Th is is an i mportant feature,
as many PXI-compatible systems may not require components that do not
implement PXI-specific features. For example, you may want to use a
standard CompactPCI network interface card in a PXI chassis.

The signals on the P1 connector of the backplane meet the requirements of
the CompactPCI specification for both the periph eral and sy stem modules .

The PXI-specific signals are located on P2 and are found on only
the signals that are reserved or not used in the CompactPCI 64-bit
specification. Therefore, all modules that meet the requirements of the
CompactPCI 64-bit specification will function in the PXI-1025 MegaPAC.

System Controller Slot

The System Controller slot is Slot 1 of the chassis as defined by the PXI
specification. It has three controller expansion slots, which are used for
system controller modules that are wider than one slot. As defined in the
PXI specification, these slots allow the controller to expand to the left to
prevent the controller from using up peripheral slots.

Star Trigger Slot

The Star Trigger (ST) slot is Slot 2. This slot has a dedicated trigger line
between each peripheral slot (see Figure 1-3). This slot is intended for
modules with ST functionality that can provide individual triggers to all
other peripherals. Additionally, you can use the ST slot as a high-precision
10 MHz clock source. However, if you do not require advanced trigger
functionality, you can install any standard peripheral module into this slot.

Peripheral Slots

There are seven peripheral slots including the ST slot.

Local Bus

The PXI backplane’s local bus is a daisy-chained bus that connects each
peripheral slot with its adjacent peripheral slots to the left and right, as
shown in Figure 1-3.

PXI-1025 MegaPAC User Manual 1-4 www.ni.com

Chapter 1 Getting Started

For example, a given peripheral slot’s right local bus connects to the
adjacent slot’ s left local b us, an d so on . Each local b us is 13 lines wide and
can pass analog signals between cards or provide a high-speed side-band
communication path that does not affect the PCI bandwidth.

Local bus signals may ran ge from high-speed TTL signals t o analog signals
as high as 42 V. Initialization software keys adjacent boards to prohibit
the use of incompatible boards. This software uses the configuration
information specific to each peripheral board to evaluate compatibility.
This method is a flexible way to define local bus functionality that is not
limited by hardware keying.

System Controller Slot 1

Star Trigger/Peripheral Slot 2

The eight PXI trigger lines are bused to each slot. You can use the trigger
lines in a variety of ways. For exam ple, you can us e triggers to s ynchronize
the operation of several different PXI peripheral modules. In other
applications, one module can control carefully timed sequences of
operations performed on other modules in the system. Modules can
pass triggers to one another, allowing precisely timed responses to
asynchronous external events the system is monitoring or controlling.

System Reference Clock

The PXI-1025 MegaPAC supplies the PXI 10 MHz system clock signal
(PXI_CLK10) independently to each peripheral slot. An independent
buffer (having a source impedance matched to the backplane and a skew
of less than 1 ns between slots) drives the clock signal to each peripheral
slot. You can use this common reference clock signal to synchronize
multiple modules in a measurement or control system. You can drive
PXI_CLK10 from an external source through the PXI_CLK10_IN pin
on the P2 connector of the Star Trigger Slot. (See Table B-4,

Connector Pinout for the Star Trigger Slot

Sourcing an external clock on this pin automatically disables the
backplane’s 10 MHz source.

Site Considerations

The PXI-1025 MegaPAC is designed to operate on a bench or in an
instrument rack. Determine h ow you want to use your PXI-1025 MegaPAC
and follow the appropriate installation instructions.

To facilitate power supply and module cooling, air enters through filters
and fan inlets located in the lower rear of the chassis and exits through
the upper section on the rear panel, as shown in Figure 2-1. Place your
PXI-1025 MegaPAC on a bench top or in an instrument rack so that the
fans (air inlets) and the air outlet apertures along the rear of the chassis
have adequate ventilation. Keep other equipment a minimum of 3.0 in.
(76.2 mm) away from the air inlets and outlets.

Installing PXI Modules

Caution

Turn off the chassis power before installing CompactPCI or PXI modules.

Install a module into a chassis slot by first placing the module’s card edges
into the front module guides (top and bottom), as shown in Figure 2-3.
Slide the module into the chassis (making sure that the injector/ejector
handle is pushed down as shown in Figure 2-4.

When you begin to feel resistance, push up on the injector/ejector handle
to inject the card into the frame. Secure the module’s front panel to the
chassis using the module’s front-panel mounting screws.

Interior Cleaning

Exterior Cleaning

Use a dry, low-velocity stream of air to clean the interior of the chassis.
Use a soft-bristle brush for cleaning around components. If you must use
a liquid for minor interior cleaning, use a 75% isopropyl alcohol solution
and rinse with deionized water.

Clean the exterior surfaces of the chassis with a dry lint-free cloth or a
soft-bristle brush. If any dirt remains, wipe with a cloth moistened in a mild
soap solution. Remove any soap residue by wiping with a cloth mo istened
with clear water. Do not use abrasive compo unds on any part of the chassis.

To clean the LCD display, wipe with lens paper or optical cloth.

provide individual triggers to all other peripherals.

System controller A module configured for installation in Slot 1 o f a PXI chassis. This de vice

is unique in the PXI system in that it performs the PCI system controller
functions, including clock sour cing and arbitration for data transfers across
the backplane. Installing such a device into any other slot can damage the
device, the PXI backplane, or both.
