SCC Quick Start Guide
This document explains how to install and configure National Instruments Signal Conditioning
Components (SCC) modules with NI-DAQmx. SCC modules work with NI M Series, E Series, and
B Series DAQ devices. This document assumes you have already installed, configured, and tested your
NI application and driver software and the data acquisition (DAQ) device you will connect to the
SC-2345/2350 carrier. If you have not done so, refer to the DAQ Getting Started Guide included with
the DAQ device, available on the NI-DAQ CD, and from
Throughout this document, abbreviations containing X or XX are used to refer to families of related
device model numbers.
SCC-AIXX—refers to the SCC-AI01, SCC-AI02, SCC-AI03, SCC-AI04, SCC-AI05, SCC-AI06,
SCC-AI07, SCC-AI13, and SCC-AI14.
SCC-LPXX—refers to the SCC-LP01, SCC-LP02, SCC-LP03, and SCC-LP04.
SCC-SGXX—refers to the SCC-SG01, SCC-SG02, SCC-SG03, SCC-SG04, and SCC-SG24.
SCC-TC0X—refers to the SCC-TC01 and SCC-TC02.
SCC-XX—refers to any SCC module.
Step 1. Unpacking the Carrier and Modules
Remove the module from the package and inspect the module for loose components or any sign of
damage. Notify NI if the module appears damaged in any way. Do not install a damaged module into
the carrier.
For safety and compliance information, refer to the device documentation packaged with the device,
ni.com/manuals, or on NI-DAQmx CD that contains the device documentation.
at
ni.com/manuals before continuing.
The following symbols may be on the device:
This symbol denotes a caution, which advises you of precautions to take to avoid injury, data loss, or a
system crash. When this symbol is marked on the product, refer to the Read Me First: Safety and
Radio-Frequency Interference document, shipped with the product, for precautions to take.
When this symbol is marked on a product, it denotes a warning advising you to take precautions to avoid
electrical shock.
When this symbol is marked on a product, it denotes a component that may be hot. Touching a
component may result in bodily injury.
Step 2. Verifying the Components
Verify that you have the following SCC system components.

To install NI-DAQmx, refer to the DAQ Getting Started Guide. To install the SC-2345/2350 carrier, refer
to the SC-2345/2350 Carrier User Manual. All NI documents are available at
SCC Quick Start Guide 2 ni.com
ni.com/manuals.
Step 3. Cabling the SC-2345/2350 Carrier to the DAQ Device
Caution Refer to the Read Me First: Safety and Radio-Frequency Interference document before
removing equipment covers or connecting or disconnecting any signal wires. Follow proper ESD
precautions to ensure you are grounded before installing the hardware.
Verify that the DAQ device is installed in the computer. If the DAQ device is not installed, refer to the
DAQ Getting Started Guide for installation instructions.
Connect the SC-2345/2350 carrier to the DAQ device with a 68-pin shielded cable. If you are using an
M Series DAQ device with two connectors, connect the cable to connector 0 or 1. Use connector J24,
shown in Figure 1, on the SC-2345/2350 carrier.

The chassis ground terminal on the SC-2345/2350 carrier and the electromagnetic interference (EMI)
gasket attached to the strain relief of the SC-2345 connector block are used to ground a floating source
(1 mA maximum). Do not use these terminals as safety earth grounds. For more information about the
SC-2345/2350 carrier, refer to the SC-2345/2350 Carrier User Manual.

Step 4. Setting Up the SC-2345/SC-2350 Carrier
The following section describes how to set up features common to both the SC-2345 and the SC-2350
carriers.
Procedure 1: Installing the Connectors and Panelettes
If you have selected an SC carrier with configurable connectors, install the connector and interface
panelettes. Some panelettes occupy more than one panelette slot. Table 1 lists the panelette
specifications.

You can install a blank panelette into any unused panelette opening. Complete the following steps to
install the I/O panelettes:
1. Remove the blank panel before installing any I/O panelettes on the rear of the SC-2345/2350
with configurable connectors.
2. Place the lower edge of the I/O panelette in the groove at the bottom of the enclosure opening.
3. Tilt the panelette top back into the enclosure.
4. Secure the panelette with either one, two, or three (depending on the type of I/O panelette)
M2.5 × 6 panhead screws that are included with the panelette.
5. Connect the lead wires from the panelette to the screw terminals of the SCC modules or to the
42-pin screw terminal block inside the SC-2345/2350 carrier.
Procedure 2: Applying I/O Panelette Labels
The SC-2345 with Configurable Connectors and the SC-2350 are shipped with a sheet of labels to apply
to the I/O panelettes as shown in Figure 5. The label sheet has both printed labels and blank labels you
can customize. You can use two labels on single-width I/O panelettes and three or more labels on wider
panelettes.

Step 5. Connecting the Signals
Caution Always refer to the specifications in the SCC-XX module user guide before connecting
signals. Exceeding specified module ratings can create a shock or fire hazard and can damage any
or all of the devices connected to the module.
Refer to the SCC module user guide to confirm signal names. Complete the following steps:
1. Remove power from the signal lines.
2. Strip 7 mm (0.25 in.) of insulation from the ends of the signal wires.
3. Insert the wires into the screw terminals. The SCC-XX module has a fixed screw-terminal
receptacle and a removable screw-terminal block, as shown in Figure 6.

4. Tighten the screws to 0.5 to 0.6 N · m (4.4 to 5.3 lb · in.) of torque.
5. Make sure the strain-relief bar is installed as shown in Figures 3, 4, and 5. If necessary, reinstall
and tighten the strain-relief screws.
6. Close or replace the top cover.
7. Reinsert and tighten the cover screws to ensure proper shielding.
For complete signal-connection information, refer to the SCC-XX module user guide. For more
information about using the SC-2345, refer to the SC-2345/2350 Carrier User Manual.

SC-2350: Connecting TEDS Sensors
If you are using an IEEE P1451.4 Transducer Electronic Data Sheet-compatible smart sensor, complete
the following steps to connect the TEDS DATA and RETURN signals. Refer to Figure 7 when
completing the following steps:
1. Connect the DATA signal to the DATA+ screw terminal on the TEDS screw terminal.
2. Connect the RETURN signal to the
