NI CVS-1458
Compact Vision System with GigE Vision and Reconfigurable I/O
The NI CVS-1458 is a compact vision system that acquires, processes, and displays images from
GigE Vision cameras. The NI CVS-1458 ships with preloaded Windows Embedded Standard 7
64-bit. This document explains how to install and configure the NI CVS-1458.
Required Components
The following items are necessary to set up and use the NI CVS-1458:
NI CVS-1458 device
One or two GigE Vision cameras
One CAT 5e or CAT 6 1000Base-T Ethernet cable per GigE Vision camera
One CAT 5 10/100Base-TX, CAT 5e, or CAT 6 1000Base-T Ethernet cable to connect the
device 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.

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
NI CVS-1458 Getting Started Guide |© National Instruments |3
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.

Connecting GigE Vision Cameras
The NI CVS-1458 supports 2 GigE Vision cameras. The system is capable of supplying Power
over Ethernet (PoE) to 2 cameras simultaneously. Complete the following steps to connect
cameras to the NI CVS-1458.
1. Connect an Ethernet cable to a GigE Vision camera, then connect the other end to the
NI CVS-1458 PoE PORT 0. Repeat this step for PoE PORT 1 if you are connecting
two cameras.
2. If the cameras support PoE, and a PoE power source is connected to the device, the PoE0
and PoE1 LEDs will illuminate.
3. Verify the ACTIVITY/LINK LED is lit.
Acquiring an Image in MAX
1. Open Measurement & Automation Explorer (MAX).
2. In the Configuration Pane, expand Devices and Interfaces.
3. Select the camera you want to test.
4. Click Snap to acquire an image.
Connecting to a Network
Complete the following steps to connect the device to a network.
1. Connect one end of an Ethernet cable to the network port on the device.
2. Connect the free end of the cable to an Ethernet hub or other network device.
3. Verify the ACTIVITY/LINK LED on the port is on or blinking.
By default, the operating system automatically attempts to connect to the network using DHCP.
If the it is unable to initiate a DHCP connection, it connects to the network with a link-local
IP address (169.254.x.x).
