software (included)

begin acquiring images. With a set of easy-to-use functions, you can

quickly create applications in National Instruments LabVIEW, C/C++,

or Visual Basic. Vision Acquisition software is compatible with IIDC-

compliant cameras. You can connect a maximum of 16 cameras to your

board and acquire from each one. Advanced functionality includes the

ability to query the camera for onboard parameters and to change

programmatic parameters programmatically. Vision Acquisition is also

compatible with Camera Link, analog, GigE, and parallel digital cameras

(through compatible NI hardware), so you can use programs written for

NI 825xR boards with a wide range of cameras without major changes

to your code.

Overview

With the National Instruments 825xR image acquisition boards, you

can build machine vision systems that trigger and synchronize two or

more IEEE 1394 cameras without requiring additional digital I/O boards

or custom circuitry. The NI PCI-8254R has 400 Mb/s of bandwidth and

two direct-connect IEEE 1394a ports that share that bandwidth. The

NI PCIe-8255R has 800 Mb/s of bandwidth shared between two direct-

connect IEEE 1394b ports (IEEE 1394a cameras are compatible with a

converter cable). Both of these boards feature NI reconfigurable I/O (RIO)

technology and include all the digital I/O you need for industrial control

and communication.

Onboard Digital I/O

About IEEE 1394

The NI 825xR series has 15 digital input lines – 13 isolated 24 V lines

and two dedicated TTL lines. There are also 14 digital output lines – four

isolated 24 V and 10 dedicated TTL. You can access all 29 digital lines

for synchronizing vision components such as cameras, triggers, and

lights. You also can use quadrature encoder inputs, product selection

lines, and general-purpose digital I/O for communicating with actuators,

PLCs, and NI programmable automation controllers (PACs).

IEEE 1394 is a PC bus standard ideally suited for machine vision. Any

IEEE 1394 camera that complies with the DCAM (or IIDC) standard works

with the National Instruments Vision Acquisition driver. With digital

image quality, simple cabling, standard software, and a lower cost, IEEE

1394 cameras are quickly replacing analog cameras in machine vision

applications. Today, there are more than 300 industrial IEEE 1394

cameras available from nearly every major vision company.

Reconfigurable I/O

Vision Acquisition Software

As with the Compact Vision System, you can extend the NI 825xR

functionality with NI RIO technology. Using the NI LabVIEW FPGA

Module, you can customize all 29 digital I/O lines to perform a wider

variety of packaging inspection, assembly verification, and robot

control applications.

NI Vision Acquisition software offers a mobile, easy-to-use solution

for acquiring images from IEEE 1394 cameras. The driver software

integrates with NI Measurement & Automation Explorer, so you can

easily configure your camera. You also can quickly set up your system

by connecting an IEEE 1394 camera to your computer and immediately
