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.
Consult the FCC web site http://www.fcc.gov for more information.
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.

Installing and Configuring
the SCXI-1129
The SCXI-1129 is a 256 crosspoint high-density matrix module. It provides
up to a 4 × 64, 2-wire switch matrix configuration on an SCXI platform.
The SCXI-1129 can also operate as four 4 ×16, 2-wire matrixes;
two 4 ×32, 2-wire matrixes; or two 8 × 16, 2-wire matrixes.
Note Common matrix terminology describes matrixes by the number of rows by the
number of columns they contain. For example, four rows by 16 columns would be written
as 4 × 16.
Through the use of special terminal blocks (refer to Table 2-1, Terminal
Block Matrix Configuration), the SCXI-1129 can become many different
matrix types. Refer to Table 1-1 for a complete list of matrix
configurations.
To accommodate even larger testing needs, you can expand the matrix size
by combining additional modules. With the use of terminal blocks, you can
expand rows on the 4 × 16 and 16 × 16 matrixes, and you can expand rows
and columns on the 4 × 64 and the 8 × 32 matrixes. These modules support
the analog bus through a special adapter, the high-voltage analog bus
(HVAB) backplane adapter in the SCXI-1357/1358 kit, at the rear of the
module. This adapter allows you to expand the HVAB without complicated

wiring. By connecting multiple modules to the HVAB adapter, it is possible
to expand the matrix size without external row or column connectors. For
more information on matrix expansion, refer to the Matrix Expansion
section in Chapter 2, Using the SCXI-1129.
The SCXI-1129 is designed to work well at both low and high voltages.
For low-voltage measurements, the SCXI-1129 uses relays with < 9 µV
thermal offset to ensure accurate measurements. For details, refer to
Appendix A, Specifications.

the driver.
6. After completing the installation, power off your computer.
Safety Information
The following cautions contain important safety information concerning
hazardous voltages.
Cautions Do not operate the device in an explosive atmosphere or where there may be
flammable gases or fumes.
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 powered off. To avoid a shock hazard, do not perform
procedures involving cover or shield removal unless you are qualified to do so and
disconnect all field power prior to removing covers or shields.
Equipment described in this document must be used in an Installation Category I1
environment per IEC 60664-1. This category requires local level supply mains-connected
installation.
Do not operate damaged equipment. The safety protection features built into this device
can become impaired if the device becomes damaged in any way. If the device is damaged,
1Category I refers to a signal level such as voltages of an isolation transformer secondary on a PWB.

Chapter 1 Installing and Configuring the SCXI-1129
SCXI-1129 User Manual 1-4 ni.com
power the device off and do not use it until service-trained personnel can check its safety.
If necessary, return the device to National Instruments for service and repair to ensure that
its safety is not compromised.
Do not operate this equipment in a manner that contradicts the information specified in this
document. Misuse of this equipment could result in a shock hazard.
Do not substitute parts or modify equipment. Because of the danger of introducing
additional hazards, do not install unauthorized parts or modify the device. Return the
device to National Instruments for service and repair to ensure that its safety features are
not compromised.
Yo u must insulate all of your signal connections to the highest voltage with which the
SCXI-1129 can come in contact.
When using the device with high common-mode voltages, you must insulate your signal
wires for the highest input voltage. National Instruments is not liable for any damages or
injuries resulting from inadequate signal wire insulation. Use only 26-20 AWG wire with
a minimum voltage rating of 150 V and a temperature value of 60 °C for measuring up
to 150 V.
When connecting or disconnecting signal lines to the SCXI terminal block screw terminals,
make sure the lines are powered off. Potential differences between the lines and the SCXI
ground can create a shock hazard while you connect the lines.
Connections, including power signals to ground and vice versa, that exceed any of the
maximum signal ratings on the SCXI device can create a shock or fire hazard, or can
damage any or all of the boards connected to the SCXI chassis, the host computer, and the
SCXI device. National Instruments is not liable for any damages or injuries resulting from
incorrect signal connections.
If hazardous voltages (≥30 Vrms and42.4V
peak or 60 VDC) are present, you must connect
a safety earth-ground wire to the terminal block safety-ground lug, shown in Figure 1-1.
This complies with safety agency requirements and protects against electric shock when
the terminal block is not connected to the chassis. To connect the safety earth-ground to the
safety-ground lug, run an earth-ground wire from the signal source to the terminal block.
National Instruments is not liable for any damages or injuries resulting from inadequate
safety earth-ground connections.
Do not loosen or re-orient the safety-ground lug hardware when connecting the
safety-ground wire; to do so reduces the safety isolation between the high voltage and
safety ground.

Chapter 1 Installing and Configuring the SCXI-1129
