INSTALLATION GUIDE
SCXI -1353 SHIELDED CABLE ASSEMBLY
This guide describes how to install the National Instruments SCXI-1353
shielded cable assembly between a 100-pin E Series data acquisition
(DAQ) device and two SCXI modules. The SCXI-1353 consists of an
SH1006868 cable, an SCXI-1349 shielded cable adapter, and an
AI-48/DIO-24 adapter.
Introduction
The SCXI-1353 makes a low-noise, long-distance connection between
a 100-pin E Series DAQ device and two SCXI modules. The SH1006868
cable is available in lengths of 1, 2, 5, and 10 m. The SH1006868 cable
is Y-shaped, with a 100-pin male connector and two 68-pin female
connectors. One branch of the cable is labeled MIO-16, and the other
branch is labeled EXTENDED I/O.
The 100-pin connector of the cable attaches to a 100-pin E Series DAQ
device. The 68-pin connector on the MIO-16 branch of the cable attaches
to an SCXI-1349. The 68-pin connector on the EXTENDED I/O branch of
the cable attaches to an AI-48/DIO-24. The SCXI-1349 and AI-48/DIO-24
can attach to a variety of SCXI modules. Both these adapters have breakout
connectors that you can use to connect to other SCXI accessories, such as
the SCXI-1180 and the SCXI-1351.

Safety Information
The following section contains important safety information that you must
follow when installing and using the product.
Do not operate the product in a manner not specified in this document.
Misuse of the product can result in a hazard. You can compromise the
safety protection built into the product if the product is damaged in any
way. If the product is damaged, return it to National Instruments for repair.
Do not substitute parts or modify the product except as described in this
document. Use the product only with the chassis, modules, accessories, and
cables specified in the installation instructions. You must have all covers
and filler panels installed during operation of the product.
Do not operate the product in an explosive atmosphere or where there may
be flammable gases or fumes. Operate the product only at or below the
pollution degree stated in the Specifications section. Pollution is foreign
matter in a solid, liquid, or gaseous state that can reduce dielectric strength
or surface resistivity. The following is a description of pollution degrees:
• Pollution degree 1 means no pollution or only dry, nonconductive
pollution occurs. The pollution has no influence.
• Pollution degree 2 means that only nonconductive pollution occurs in
most cases. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
• Pollution degree 3 means that conductive pollution occurs, or dry,
nonconductive pollution occurs that becomes conductive due to
condensation.
Clean the product with a soft nonmetallic brush. Make sure that the product
is completely dry and free from contaminants before returning it to service.
You must insulate signal connections for the maximum voltage for which
the product is rated. Do not exceed the maximum ratings for the product.
Remove power from signal lines before connecting them to or
disconnecting them from the product.
Operate this product only at or below the installation category stated in the
Specifications section.
The installation category for this device, installation category I, is for
measurements performed on circuits not directly connected to MAINS1.
1 MAINS is defined as the electricity supply system to which the equipment concerned is designed to be connected either for
powering the equipment or for measurement purposes.

SCXI-1353 Shielded Cable Assembly 4 ni.com
This category is a signal level such as voltages on a printed wire board
(PWB) on the secondary of an isolation transformer.
Examples of installation category I are measurements on circuits not
derived from MAINS and specially protected (internal) MAINS-derived
circuits.
Installing the SCXI-1353 Shielded Cable Assembly
Perform the following steps to install the SCXI-1353. Refer to Figure 1 for
the installation procedure.
Figure 1. SCXI-1353 Installation
1. Turn off the computer and SCXI chassis.
2. Install the SCXI modules in the SCXI chassis following the
instructions in the module user manual.

3. Insert the 50-pin female connector on the rear of the SCXI-1349 into
the rear signal connector of the SCXI module that passes analog
signals to the 100-pin E Series DAQ device.
4. Screw the rear panel of the SCXI-1349 to the threaded strips in the rear
of the SCXI chassis to secure the adapter.
5. Connect the end of the cable labeled MIO-16 to the 68-pin connector
of the SCXI-1349.
6. Insert the 50-pin female connector on the rear of the AI-48/DIO-24
into the rear signal connector of the SCXI module or feedthrough panel
that connects to pins 51–100 of the DAQ device.
7. Screw the rear panel of the AI-48/DIO-24 to the threaded strips in the
rear of the SCXI chassis to secure the adapter.
8. Connect the end of the cable labeled EXTENDED I/O to the 68-pin
connector of the AI-48/DIO-24.
9. Connect the 100-pin end of the cable to the I/O connector of the DAQ
device.
10. Use the tie wraps to secure the cable to a fixed object to relieve the
strain on the cable. Strain relief is necessary because the SCXI-1353
has a long, stiff backshell that can exert leverage on the DAQ device
connector.
Connections and Pin Assignments
Table 1 lists the pin assignments for connections between the 100-pin
E Series DAQ device and the MIO-16 cable. Table 2 lists the pin
assignments for connections between the 100-pin E Series DAQ device and
the EXTENDED I/O cable. The 100-pin E Series DAQ device you use
determines which SCXI modules you can use with the SCXI-1353.
