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.
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.
About IEEE 1394
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.
Onboard Digital I/O
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).
Vision Acquisition Software
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
Reconfigurable I/O
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.
