NI CVS-1459
Compact Vision System with USB3 Vision and Reconfigurable I/O
The NI CVS-1459 is a compact vision system that acquires, processes, and displays images
from USB3 Vision cameras. The NI CVS-1459 ships with preloaded Windows Embedded
Standard 7 64-bit. This document explains how to install and configure the NI CVS-1459.
Required Components
The following items are necessary to set up and use the NI CVS-1459.
• NI CVS-1459
• One or two USB3 Vision cameras
• One USB 3.0 cable per USB3 Vision camera
• One CAT 5 10/100Base-TX, CAT 5e, or CAT 6 1000Base-T Ethernet cable to connect the
device to the development computer or to a network.
Note A CAT 5e or CAT 6 1000Base-T Ethernet cable is required to achieve
1,000 Mbps (Gigabit) Ethernet performance. CAT 5e and CAT 6 Ethernet
cables adhere to higher electrical standards required for Gigabit Ethernet
communication. CAT 5 cables are not guaranteed to meet the necessary
requirements. While CAT 5 cables may appear to work at 1,000 Mbps, CAT 5
cables are likely to cause bit errors resulting in degraded network performance.
• Monitor
• Keyboard
• Mouse
• A compatible power supply, such as the NI PS-15 Power Supply (part number
781093-01)

Safety Information
Caution The following paragraphs contain important safety information you must
follow when installing and operating the device.
Do not operate the device in a manner not specified in the documentation. Misuse of the
device may result in a hazard and may compromise the safety protection built into the device.
If the device is damaged, turn it off and do not use it until service-trained personnel can check
its safety. If necessary, return the device to National Instruments for repair.
Keep away from live circuits. Do not remove equipment covers or shields unless you are
trained to do so. If signal wires are connected to the device, hazardous voltages can exist even
when the equipment is turned off. To avoid a shock hazard, do not perform procedures
involving cover or shield removal unless you are qualified to do so. Disconnect all field power
prior to removing covers or shields.
Because of the danger of introducing additional hazards, do not install unauthorized parts or
modify the device. Use the device only with the chassis, modules, accessories, and cables
specified in the installation instructions. All covers and filler panels must be installed while
operating the device.
This is a Pollution Degree 2 device. Do not operate the device in an explosive atmosphere or
where flammable gases or fumes may be present. Operate the device only at or below the
pollution degree stated in the specifications. Pollution consists of any foreign matter—solid,
liquid, or gas—that may reduce dielectric strength or surface resistivity. The following is a
description of pollution degrees.
• Pollution Degree 1—No pollution or only dry, nonconductive pollution occurs. The
pollution has no effect.
• Pollution Degree 2—Normally only nonconductive pollution occurs. Occasionally,
nonconductive pollution becomes conductive because of condensation.
• Pollution Degree 3—Conductive pollution or dry, nonconductive pollution occurs.
Nonconductive pollution becomes conductive because of condensation.

Clean the device and accessories by brushing off light dust with a soft, nonmetallic brush.
Remove other contaminants with a stiff, nonmetallic brush. The unit must be completely dry
and free from contaminants before returning it to service.
You must insulate signal connections for the maximum voltage for which the device is rated.
Do not exceed the maximum ratings for the device. Remove power from signal lines before
connection to or disconnection from the device.
