Chapter 1 Getting Started with the cDAQ Chassis
Using the cDAQ Chassis
The cDAQ system consists of three parts: C Series module(s), the cDAQ module interface, and
the STC3, as shown in Figure 1-20. These components digitize signals, perform D/A
conversions to generate analog output signals, measure and control digital I/O signals, and
provide signal conditioning.

C Series Module
National Instruments C Series modules provide built-in signal conditioning and screw terminal,
spring terminal, BNC, D-SUB, or RJ-50 connectors. A wide variety of I/O types are available,
allowing you to customize the cDAQ system to meet your application needs.
C Series modules are hot-swappable and automatically detected by the cDAQ chassis.
I/O channels are accessible using the NI-DAQmx driver software.
Because the modules contain built-in signal conditioning for extended voltage ranges or
industrial signal types, you can usually make your wiring connections directly from the C Series
modules to your sensors/actuators. In most cases, the C Series modules provide isolation from
channel-to-earth ground and channel-to-channel.
For more information about which C Series modules are compatible with the cDAQ chassis, go
