Technical Application Note (TAN2015009): Getting Started with NI Compact Vision System
This application note provides information on how to setup and use Point Grey GigE Vision and USB3 Vision cameras with NI Compact Vision System (CVS) devices.
The instructions below apply to both NI CVS 1458RT (GigE Vision compact device) and NI CVS 1459RT (USB3 Vision compact device).
Before you use your Point Grey camera, we recommend that you are aware of the following resources available from the Point Grey Downloads page:
Getting Started Manual for the camera—provides information on installing components and software needed to run the camera.
Technical Reference for the camera—provides information on the camera’s specifications, features and operations, as well as imaging and acquisition controls.
Firmware updates—ensure you are using the most up-to-date firmware for the camera to take advantage of improvements and fixes.
The NI CVS device comes with a primary GigE port as well as VGA port. During development phrase, you can connect your NI CVS device to your development PC's Gigabit Ethernet port. You compile your program on your development PC and deploy it to your CVS device. Once your program is finalized and deployed to the CVS device, you can connect a monitor to it (to view results) and disconnect it from the development PC.

To setup NI CVS device:
Connect the primary network from the CVS device to your development PC.
The primary network port on the NI CVS device is labeled with “ACT/LINK”. NI CVS devices are pre-configured to use DHCP or Link Local addressing.
Example NI CVS Device Primary Network Configuration
NI provides two options for developing machine vision applications:
Note that you need to install the following modules in the order specified in NI’s Getting Started Page for NI CVS 1459RT:
The NI CVS device’s primary network connection is set to DHCP by default. It waits for your DHCP server to assign an address before it shows up in Vision Builder AI 2014. If DHCP fails to assign an IP address to the camera, the connection falls back to link local addressing.
Using Vision Builder AI 2014:
Using NI LabVIEW:
If you cannot find your NI-CVS, you can choose the option to specify a target or device by IP address.
You can see the acquired images on your NI CVS device by using one of the software choices below.
After you have finished with development, you can disconnect the Ethernet connection between your development PC and the CVS device. The CVS device acts as a standalone system, you can connect a monitor to it and inspect your program output.
To acquire images in Vision Builder AI 2014:
To acquire images in LabVIEW:
You can download Point Grey’s sample LabVIEW VI from Programming Point Grey Cameras in National Instruments (NI ) LabVIEW. Please note you can only use IMAQdx examples with NI’s CVS device. Point Grey’s ActiveX examples are not supported by the NI CVS device.
To acquire images in NI-MAX:
You can quickly check if your camera can grab images on the CVS device, using NI-MAX on your development PC.
What if the connection is lost to the NI CVS 1458RT device?
You may see this error if your NI CVS device has an inconsistent IP setting.
