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 industrial-
commercial locations only) or Class B (for use in residential or commercial locations). Depending on where it is
operated, this product could be subject to restrictions in the FCC rules. (In Canada, the Department of
Communications (DOC), of Industry Canada, regulates wireless interference in much the same way.)
Digital electronics emit weak signals during normal operation 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 apply in the following sections. (Some products may not be labeled 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 operated.
FCC Class B products display either a FCC ID code, starting with the letters EXN,
or the FCC Class B compliance mark that appears as shown here on the right.
FCC/DOC Warnings
This equipment generates and uses radio frequency energy and, if not installed and used in strict accordance with the
instructions in this manual and the CE Mark Declaration of Conformity**, may cause interference to radio and
television reception. Classification requirements are the same for the Federal Communications Commission (FCC)
and the Canadian Department of Communications (DOC).
Changes or modifications not expressly approved by National Instruments could void the user’s authority to operate
the equipment under the FCC Rules.
Class A
Federal Communications Commission
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own expense.
Canadian Department of Communications
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.

system, and explains the operation of each functional unit.
Functional Overview
operation. When the desktop PC or the CompactPCI/PXI controller
powers on, the system BIOS scans its local PCI bus for devices. When it
finds the primary interface of the MXI-3 card, it initiates configuration
cycles and searches for PCI devices on the secondary side.
Figure 3-1 shows the basic architecture of the MXI-3 system. The MXI-3
card interfaces to the PCI bus with the National Instruments MXI-3 ASIC.
The ASIC converts PCI transactions into a 20-bit wide parallel bus.
A parallel to serial converter transmits the 20-bit data as serial data at
1.5 Gbits/s. If you are using copper cable, the system sends the serial data
through the cable as a differential electrical signal. If you are using
fiber-optic cable, the system converts the serial data to light using a
VCSEL module.
On the other side of the system, the MXI-3 card receives the data, using
high-speed photodetectors to convert light signals back to digital data in the
case where a fiber-optic MXI-3 is used. A serial to parallel converter then
converts the digital serial data to the original 20-bit wide packets of data for
the MXI-3 ASIC. MXI-3 then recreates the PCI transaction with
appropriate modifications.

National Instruments MXI-3 ASIC
The MXI-3 ASIC, which contains most of the logic in the two-board
system, is a PCI master/slave device using the PCI-PCI bridge register set.
MXI-3 uses data queues to store data for transmission, and also uses data
queues to store received data waiting for access to the target PCI bus.
MXI-3 ASIC transmits data to the parallel-to-serial converters, and
receives data from the serial-to-parallel converters.
