Getting Started with the
cDAQ Controller
The National Instruments CompactDAQ cDAQ-9138 controller features the 1.06 GHz Celeron
processor. The National Instruments CompactDAQ cDAQ-9139 controller features the
1.33 GHz Intel Core i7 processor. The NI cDAQ-9138 and NI cDAQ-9139 are available as a
Windows Embedded Standard 7 (WES7) or a LabVIEW Real-Time system.
This chapter contains information about getting started with the cDAQ controller with Windows
and with LabVIEW Real-Time:
• For NI cDAQ-9138/9139 for Windows, refer to the Installing the NI cDAQ-9138/9139 for
Windows section
• For NI cDAQ-9138/9139 for LabVIEW Real-Time, refer to the Installing the
NI cDAQ-9138/9139 for LabVIEW Real-Time section
The eight-slot cDAQ controller has a number of standard interfaces and combines with C Series
modules to measure a broad range of analog and digital I/O signals that can be logged to the local
hard drive. For specifications, refer to the specifications document for your cDAQ controller.
For module specifications, refer to the documentation included with your C Series module(s) or
ni.com/manuals.

Electromagnetic Compatibility Guidelines
This product was tested and complies with the regulatory requirements and limits for
electromagnetic compatibility (EMC) stated in the product specifications. These requirements
and limits provide reasonable protection against harmful interference when the product is
operated in the intended operational electromagnetic environment.
This product is intended for use in residential, commercial and industrial locations. However,
harmful interference may occur in some installations or when the product is connected to a
peripheral device or a test object. To minimize interference with radio and television reception
and prevent unacceptable performance degradation, install and use this product in strict
accordance with the instructions in the product documentation.
Furthermore, any modifications to the product not expressly approved by National Instruments
could void your authority to operate it under your local regulatory rules.
Caution To ensure the specified EMC performance, operate this product only with
shielded cables and accessories. Note that the input DC power cables may be
unshielded.
Caution To ensure the specified EMC performance, do not connect the power input
to a DC mains supply or to any supply requiring a connecting cable longer than 3 m
(10 ft). A DC mains supply is a local DC electricity supply network in the
infrastructure of a site or building.
Caution To ensure the specified EMC performance, the length of any cable
connected to the video port must be no longer than 3 m (10 ft). The length of any
cable connected to the RS-232, USB, and MXI-Express ports must be no longer than
30 m (100 ft).
Caution To ensure the specified EMC performance, install snap-on, ferrite bead
(National Instruments part number 711849-01, included in the shipping kit) in
accordance with the product installation instructions.
Hardware Symbol Definitions
The following symbols are marked on your cDAQ controller.
Caution When this symbol is marked on a product, refer to the Safety Guidelines

The cDAQ controller ships in an antistatic package to prevent electrostatic discharge (ESD).
ESD can damage several components on the device.
Caution Never touch the exposed pins of connectors.
To avoid ESD damage in handling the device, take the following precautions:
• Ground yourself with a grounding strap or by touching a grounded object.
• Touch the antistatic package to a metal part of your computer controller before removing
the device from the package.
Remove the device from the package and inspect it for loose components or any other signs of
damage. Notify NI if the device appears damaged in any way. Do not install a damaged device
in your computer or controller.

Wiring Power to the cDAQ Controller
The cDAQ controller requires an external power source as described in the Power Requirements
section of the specifications document for your cDAQ controller. Some suggested NI power
supplies are listed in Table 1-10. The cDAQ controller filters and regulates the supplied power
and provides power to all of the modules. The cDAQ controller has a primary power input, V1,
and a secondary power input, V2. The POWER LED on the front panel identifies the power input
in use. When the LED is lit green, V1 is in use; when the LED is lit yellow, V2 is in use.
1-12 | ni.com
NI cDAQ-9138/9139 User Manual
Caution Do not connect V2 to a DC mains supply or to any supply requiring a
connecting cable longer than 3 m (10 ft). A DC mains supply is a local DC electricity
supply network in the infrastructure of a site or building.
Complete the following steps to connect a power source to the cDAQ controller.
1. Make sure the power source is turned off.
2. Install the ferrite shipped with the cDAQ controller across the negative and positive leads
of the power source, approximately 50 to 75 mm (2 to 3 in.) from the ends of the leads near
the cDAQ controller, as shown in Figure 1-7.
Figure 1-7. Installing the Ferrite on the Power Leads
3. Loosen the connector screw flanges and remove the power screw terminal connector plug
from the cDAQ controller. Figure 1-8 shows the terminal screws, which secure the wires in
the screw terminals, and the connector screw flanges, which secure the connector plug on
the front panel.

Caution Do not tighten or loosen the terminal screws on the power connector while
the power is on.
4. Connect the positive lead of the primary power source to the V1 terminal of the power
connector plug and tighten the terminal screw.
5. Connect the negative lead of the primary power source to one of the C terminals of the
power screw terminal connector plug and tighten the terminal screw.
6. Optionally, you can connect the positive lead of a secondary power source to the V2
terminal and the negative lead to the other C terminal.
© National Instruments | 1-13
Chapter 1 Getting Started with the cDAQ Controller
7. Install the power connector plug on the front panel of the cDAQ controller and tighten the
connector screw flanges.
8. Turn on the external power source(s).
The cDAQ controller uses V1 if the voltage across V1 and C is 9 V or greater. If the V1-to-C
voltage drops below 9 V, the cDAQ controller switches to V2. If the V2-to-C voltage is less than
9 V, operation may be interrupted.
Note If the cDAQ controller is using V1 and a secondary power source is
connected to V2, there is a small leakage current on V2. The leakage current depends
on the V2-to-C voltage. Refer to the Power Requirements section of the
specifications document for your cDAQ controller for nominal values of this leakage
current.
If the power source is connected to the power connector using long wiring with high DC
resistance, the voltage at the power connector may be significantly lower than the specified
voltage of the power source.
The C terminals are internally connected to each other but are not connected to chassis ground.
You can connect the C terminals to chassis ground externally. Refer to the Power Requirements
section of the specifications document for your cDAQ controller for information about the
power supply input range. Refer to the Safety Voltages section of the specifications document
for your cDAQ controller for information about the maximum voltage from terminal to chassis
ground.
Mounting the cDAQ Controller
You can use the cDAQ controller on a desktop or mount it to a panel, wall, DIN rail, or rack. For
accessory ordering information, refer to the pricing section of the NI cDAQ-9138/9139 product
page at ni.com.
Note The cDAQ controller was designed and tested in multiple mounting
configurations. The varied mounting orientations or configurations can reduce the
maximum allowable ambient temperature and can affect the accuracy of C Series
modules in the controller. Visit
cdaqmounting for more information about mounting and accuracy.
The following sections contain instructions for the mounting methods. Before using any of these
mounting methods, record the serial number from the side of the controller. You may be unable
to read the serial number after you have mounted the controller.
Caution You must mount the controller horizontally on a flat, vertical, metallic
surface using the NI panel mount kit, part number 781919-01, to achieve an allowable
operating ambient temperature of 45 to 55 °C. Mounting the controller in a different
orientation or on a nonmetallic surface reduces the maximum allowable ambient
