Overview and Applications
The NI PCI-1424 is a digital camera image acquisition board for acquiring color
and grayscale images and controlling digital cameras. Designed for high-speed,
large-image, high-resolution digital image capture, the board can capture into
onboard memory up to 32 bits of data at a clock speed of 50 MHz, for a total
acquisition rate of 200 MB/s. Onboard memory (16 to 80 MB) gives you the
flexibility to buffer images on the board for large-image capture and sustained
real-time throughput. You can choose from two versions of the board – one
compatible with digital cameras that use RS422 and another compatible with
digital cameras that use LVDS.
The NI PCI-1422 is designed to acquire images from a wide range of digital
cameras. These boards perform high-speed, large-image, high-resolution digital
image capture and can capture up to 16 bits of data at a clock speed of 40 MHz
for a total acquisition rate of 80 MB/s. Onboard memory (16 MB) gives you the
flexibility to buffer images on the board for large-image capture and sustained
real-time throughput. There are two versions of the board – one compatible
with digital cameras that use RS422 signals and another compatible with
digital cameras that use LVDS. The PCI-1422 is ideal for both industrial and
scientific applications.
Digital Cameras
Digital cameras have several advantages over analog cameras. During
transmission, analog video is more susceptible to noise than digital video.
Digitizing at the CCD camera, rather than at the image acquisition board,
increases the signal-to-noise ratio, resulting in better accuracy. In addition,
standard digital cameras now come with 10- to 12-bit gray levels of resolution.
The higher resolution is often necessary in medical, machine vision, astronomy,
and scientific imaging applications.
Easy Camera Configuration
Configure digital image acquisition from your digital camera with
NI Measurement & Automation Explorer (MAX), which is delivered with
NI Vision Acquisition Software. This configuration utility is an interactive tool
for setting up region of interest and camera control. Plus, you can use MAX to
control the serial interface for communicating with the camera. Both the
PCI-1422 and PCI-1424 use a 100-pin SCSI-type connector that you can easily
cable to your specific camera. In addition, MAX includes specific camera setup
files, so you can quickly configure your camera for acquisition. For a list of
applicable cameras, visit
ni.com/camera.
Digital Camera Image Acquisition
Digital Image Acquisition
The PCI-1424 can acquire four channels of 8-bit data; two channels of 10-, 12-,
14-, or 16-bit data; or one channel of 24- or 32-bit data. The PCI-1422 can acquire
two channels of 8-bit data or one channel of 10-, 12-, 14-, or 16-bit data.
These boards have a serial interface and four TTL or differential digital control
lines for camera control. You can also use the adjustable onboard region of
interest (ROI) window to minimize the amount of data transferred to PC memory.
NI PCI-1422 Signaling
One version of the PCI-1422 can receive RS422 data signals. It can also drive
and receive RS422 or TTL control and enable signals. NI Vision Acquisition
Software can access these signal levels independently for data, control, and
enable lines on the 100-pin connector. Another version of the PCI-1422 is
capable of receiving data from LVDS cameras. LVDS, also known as EIA-644,
is a low-voltage differential signal protocol similar to RS422 but with lower
voltage levels.
Digital Transfer Rates
The base memory configuration for the PCI-1424 is 16. You can use onboard
memory to buffer large images before transferring them to PC memory, which
increases the overall throughput. The PCI-1422 can acquire data into onboard
memory at a rate of up to 80 MB/s and transfer data to PC memory at a rate of
100 MB/s. The PCI-1424 can acquire data at 200 MB/s into onboard memory.
Multiple-Channel Data Formatter
The multiple-channel data formatting circuitry is fully programmable, so
you can simultaneously acquire from multiple channels to build up to the
complete image.
Advanced Clock Generation
The PCI-1424 has two clock outputs for generating a frequency from 500 kHz up
to 50 MHz for digital cameras that require an external clock. The PCI-1422 has
two clock outputs for generating a frequency from 500 kHz up to 40 MHz.
Onboard Image Preparation
The PCI-1424 has four 8-bit or two 16-bit lookup tables (LUTs) for mapping the
data from one value to another in real time. The PCI-1422 has two 8-bit or one
16-bit LUT(s) for mapping the data from one value to another in real time.
In addition, setting a rectangular ROI window reduces the overall data
across the PCI bus because the pixels outside the ROI are not transferred.
You can reduce the amount of data transferred across the PCI bus by scaling
or decimating the data in hardware. You can scale the image by keeping every
second, fourth, or eighth pixel.
RS232 Serial Interface
RS232 serial lines are available on the 100-pin connector to control digital
cameras that have a serial interface.
Camera Cables
National Instruments offers 2 m cables for digital cameras, including models
by Basler, DALSA, Hamamatsu, Roper Scientific, and Pulnix. Extension cables
are also available (see the cable section). Contact National Instruments for
additional cabling options or visit
ni.com/camera.
Digital I/0
Four general-purpose, bidirectional TTL digital I/O lines are available for
triggering image acquisition.
PCI-1424 Signaling
The RS422/TTL version of the PCI-1424 can drive and receive either TTL or RS422
level signals. The driver software can access these signal levels independently
for data, control, and enable lines on the 100-pin connector. The LVDS (also
known as EIA-644) version can drive and receive LVDS and TTL signals. The
benefits of LVDS include less power consumption, longer cable lengths, less
noise, and higher clock rates.
Advanced Triggering to Work with DAQ and Motion
NI vision products are designed to work with National Instruments data
acquisition (DAQ) and motion products. The RTSI bus on the PCI-1422 and
PCI-1424 routes timing and triggering signals between boards. The buses can
synchronize video acquisition between several image acquisition devices or
between image acquisition, data acquisition, and motion control devices.
I/O Connector Signals
The 100-pin SCSI connector connects to all digital video data inputs, digital
enable inputs, camera control outputs, RS232 serial interfaces, and the external
trigger signals.
Digital Trigger Accessory
The NI D2504-1, which has four BNC connectors for digital trigger lines, is
for use with National Instruments digital camera cables.
