SCC Quick Start Guide
This document explains how to install and configure National Instruments
SCC modules with NI-DAQmx. This document assumes you have already
installed, configured, and tested the data acquisition (DAQ) device you will
connect to the SC-2345/2350 carrier. SCC modules work with NI M Series,
E Series, and B Series DAQ devices. If you have not done so, follow the
instructions in the DAQ Quick Start Guide included with the DAQ device
before continuing.

Measurement System Overview
Figure 1 depicts the measurement system overview, showing the path of
real-world physical phenomena to your measurement application.
Figure 1. Measurement System Overview
Sensors and transducers detect physical phenomena. Signal conditioning
components condition physical phenomena so that the measurement device
can receive the data. The computer receives the data through the
measurement device. Software controls the measurement system, telling
the measurement device when and from which channels to acquire or
generate data. Software also takes the raw data, analyzes it, and presents it
in a form you can understand, such as a graph, chart, or file for a report.

NI measurement devices and application software are packaged with
NI-DAQ driver softwareto program all the features of your
NI measurement device such as configuring, acquiring, and generating data
fromand sending datatoNImeasurement devices. Using NI-DAQsaves
you fromhaving to write these programs. Application software, such as
LabVIEW, LabWindows™/CVI™, Measurement Studio, and VI Logger,
sends commands to the driver, such as acquire and return a thermocouple
reading, and then displays and analyzes the data acquired.
You can use the NI-DAQ driver from NI application software or from any
programming environment that supports calling dynamic link libraries
(DLLs) through ANSI C interfaces. Regardless of the programming
environment, your DAQ application uses NI-DAQ, as shown in Figure 1.
If you have not installed, configured, and tested your DAQ device and
NI-DAQ software according to the instructions in the DAQ Quick Start
Guide, do so now.
Step 1. Unpack the Carrier and Modules
The SCC modules are shipped in an antistatic package to prevent
electrostatic damage (ESD) to the modules and their components.
Caution Never touch the exposed pins of connectors.
To avoid such damage, take the following precautions:
• Ground yourself using a grounding strap or by touching a grounded
object.
• Touch the antistatic package to a metal part of the computer chassis
before removing the module from the package.
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.
Store the SCC module in the antistatic package when not in use.
For safety and compliance information, refer to the device documentation
packaged with your device, on the NI-DAQ 7.xDevice Documentation CD
in the NI-DAQ software kit, or at ni.com/support. After you install the
Device Document Browser, device documents are accessible from
Start»Programs»National Instruments»NI-DAQ»Browse Device
Documentation.

Step 3. Cable 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/disconnecting any signal wires.
The DAQ device should already be installed in your computer. Refer to the
DAQ Quick Start 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 2, on the SC-2345/2350 carrier.
Figure 2. Connector J24 Location
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 for grounding 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.

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: Apply 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 6.
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.
Figure 6. Installing I/O Panelette Labels
Step 5. Connect the Signals
Caution Always refer to the specifications in your 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 ni.com/info and enter rdtntg in the info code field to confirm
signal names in the NI-DAQ C to NI-DAQmx Terminal Names Translation
Guide. 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 7.
Figure 7. SCC-XX Two-Part Screw-Terminal System
4. Tighten the screws to 0.5 to 0.6 N · m (4.4 to 5.3 lb – in.) of torque.
5. Check if the strain-relief bar is installed as shown in Figures 3, 4,
and 5. If necessary, reinstall and tighten the strain-relief screws.
