Compliance

FCC/Canada Radio Frequency Interference Compliance*

Determining FCC Class

The Federal Communications Commission (FCC) has rules to protect wireless communications from interference.
The FCC places digital electronics into two classes. These classes are known as Class A (for use in industrial­commercial locations only) or Class B (for use in residential or commercial locations). Depending on where it is
operated, this product could be subject to restrictions in the FCC rules. (In Canada, the Department of
Communications (DOC), of Industry Canada, regulates wireless interference in much the same way.)

Digital electronics emit weak signals during normal operation that can affect radio, television, or other wireless
products. By examining the product you purchased, you can determine the FCC Class and therefore which of the two
FCC/DOC Warnings apply in the following sections. (Some products may not be labeled at all for FCC; if so, the
reader should then assume these are Class A devices.)

FCC Class A products only display a simple warning statement of one paragraph in lengthregarding interference and
undesired operation. Most of our products are FCC Class A. The FCC rules have restrictions regarding the locations
where FCC Class A products can be operated.

FCC Class B products display either a FCC ID code, starting with the letters EXN,
or the FCC Class B compliance mark that appears as shown here on the right.

Consult the FCC web site

http://www.fcc.gov

Introduction

This chapter describes the PCI-1409 and PXI-1409 devices and describes
your software programming choices.

About Your 1409 Device

The PCI-1409 and PXI-1409 devices are high-accuracy, monochrome,
IMAQ boards for PCI, PXI, or CompactPCI chassis that support RS-170,
CCIR, NTSC, and PAL video standards as well as some nonstandard
cameras from any of four input sources. The boards feature a 10-bit
analog-to-digital converter (ADC) that converts video signals to digital
formats. The PCI-1409 acquires images in real time and can store these
images in onboard frame memory or transfer these images directly to
system memory.

The 1409 device is simple to configure so that you can easily install the
board and begin your image acquisition. The 1409 device ships with
NI-IMAQ, the National Instruments complete image acquisition driver
software you can use to directly control your 1409 device. Using NI-IMAQ,
you can quickly and easily start your application without having to program
the board at the register level.

1

Featuring low cost and high accuracy, the 1409 device is ideal for
both industrial and scientific environments. As a standalone board, the
1409 device supports four general purpose control lines that you can
configure to generate precise timing signals for controlling camera
acquisition. The 1409 device also supports four video sources and four
external I/O lines that you can use as triggers or digital I/O lines. If you
require more advanced triggering or additional I/O lines (either digital or
analog), you can use the 1409 device and NI-IMAQ with the National
Instruments data acquisition (DAQ) product line.

A common problem with many image acquisition boards is that you cannot
easily synchronize several functions to a common trigger or timing event.
The 1409 device uses its Real-Time System Integration (RTSI) bus to solve
this problem. The RTSI bus consists of the National Instruments RTSI bus

Chapter 1 Introduction

interface and ribbon cable to route additional timing and trigger signals
between the 1409 device and up to four National Instruments DAQ, Motion
Control, or other IMAQ boards in your computer.

Detailed specifications of the PCI-1409 and PXI-1409 are in Appendix A,

Specifications.

Using PXI with CompactPCI

Using PXI-compatible products with standard CompactPCI products is an
important feature provided by the PXI Specification, Revision 1.0. If you
use a PXI-compatible plug-in device in a standard CompactPCI chassis,
you will be unable to use PXI-specific functions, but you can still use the
basic plug-in device functions. For example, the RTSI bus on your
PXI-1409 device is available in a PXI chassis, but not in a CompactPCI
chassis.

The CompactPCI specification permits vendors to develop sub-buses that
coexist with the basic PCI interface on the CompactPCI bus. Compatible
operation is not guaranteed between CompactPCI devices with different
sub-buses nor between CompactPCI devices with sub-buses and PXI.
The standard implementation for CompactPCI does not include these
sub-buses. Your PXI-1409 device will work in any standard CompactPCI
chassis adhering to the PICMG 2.0 R2.1 CompactPCI core specification
using the 64-bit definition for J2.

PXI specific features are implemented on the J2 connector of the
CompactPCI bus. Table 1-1 lists the J2 pins your PXI-1409 device uses.
Your PXI device is compatible with any CompactPCI chassis with a
sub-bus that does not drive these lines. Even if the sub-bus is capable of
driving these lines, the PXI device is still compatible as long as those pins
on the sub-bus are disabled by default and not ever enabled. Damage may
result if these lines are driven by the sub-bus.

Software Programming Choices

Using NI-IMAQ, the National Instruments image acquisition driver
software, you can program your IMAQ board to acquire and save images.
You can use NI-IMAQ with other National Instruments software for a
complete image acquisition and analysis solution, as shown in Figure 1-1.
NI-IMAQ works with LabVIEW and LabWindows/CVI, as well
as conventional programming languages. National Instruments
IMAQ Vision adds powerful image processing and analysis to these
programming environments. You can also use IMAQ Vision Builder to
quickly and easily prototype your IMAQ image analysis applications.

Chapter 1 Introduction

NI-IMAQ Driver Software

The NI-IMAQ driver software is included with your IMAQ device.
NI-IMAQ has an extensive library of functions that you can call from your
application programming environment. These functions include routines
for video configuration, image acquisition (continuous and single-shot),
memory buffer allocation, trigger control, and board configuration, as
shown in Figure 1-2.

The NI-IMAQ driver software performs all of the functions required for
acquiring and saving images. The NI-IMAQ software does not perform any
image analysis. For image analysis functionality, refer to the National

Instruments IMAQ Vision section in this chapter.

NI-IMAQ has both high-level and low-level functions for maximum
flexibility and performance. Examples of high-level functions include the
functions to acquire images in single-shot or continuous mode. An example
of a low-level function is configuring an image sequence, since it requires
advanced understanding of your IMAQ device and image acquisition.

NI-IMAQ internally resolves many of the complex issues between the
computer and your IMAQ device, such as programming interrupts and
DMA controllers.

NI-IMAQ is also the interface path between LabVIEW, LabWindows/CVI,
or a conventional programming environment and your IMAQ device. The
NI-IMAQ software kit includes a series of libraries for image acquisition
for LabVIEW and Measurement Studio, which contains libraries for
LabWindows/CVI, Visual C++, and Visual Basic. These libraries are
functionally equivalent to the NI-IMAQ software.

VIDEO0 Input Mode

VIDEO0 has two different input sources via a BNC connector or a 68-pin
VHDCI port and two different input modes—referenced single-ended
(RSE) and differential (DIFF) input. When you use the BNC input for
VIDEO0, set the input mode to RSE (W1 populated). When you use
the 68-pin VHDCI port for VIDEO0, set the input mode for either RSE
or DIFF.

When in RSE mode, the video input uses one analog input line, which
connects to the video multiplexer circuitry. The negative input to the video
multiplexer is tied internally to analog ground. When in DIFF mode, the
video input uses two analog input signals. One signal connects to the
positive input of the video multiplexer circuitry while the other input
signal connects to the negative input of the video multiplexer circuitry.
Jumper W1 controls the input mode selection, as shown in Figure 2-3.
Unpopulating W1 configures VIDEO0 for DIFF mode. Populating W1
configures VIDEO0 for RSE mode.

Hardware Overview

This chapter presents an overview of the hardware functions on your
PCI/PXI-1409 board and explains the operation of each functional unit
making up the PCI/PXI-1409.

Functional Overview

The PCI/PXI-1409 features a flexible, high-speed data path optimized for
the acquisition and formatting of video data from analog cameras. The
1409 device can acquire from RS-170/NTSC, CCIR/PAL, VGA, and
progressive scan cameras, as well as from non-standard cameras such as
line scan cameras. The 1409 device digitizes analog video signals to
8 or 10 bits of resolution at sampling frequencies up to 40 MHz.

The 1409 device has a factory calibrated gain circuit to improve
measurement accuracy and board-to-board consistency. It uses a PCI
interface for high-speed data transfer, 16 MB of SDRAM for data
buffering, and region-of-interest control circuitry for optimizing the data
transfer. The 16 MB of SDRAM also allows you to acquire entire images
into on-board memory when necessary. The 1409 device includes four
external triggers, four camera control signals, seven RTSI bus triggers, and
six video synchronization signals.

10-Bit ADC

The 10-bit ADC digitizes the conditioned video signal.

IMAQ PCI/PXI-1409 User Manual 3-2 ni.com

Digital Filter and LUT

The digital filter removes chrominance from a composite color video signal
that conforms to either PAL or NTSC. The output of the digital filter passes
through the 1024
to implement simple imaging operations such as contrast enhancement,
data inversion, gamma correction, or other user-defined transfer functions.

Onboard Memory

The PCI/PXI-1409 comes with 16 MB of SDRAM for temporary storage
of the image data being transferred to the system memory through the PCI
bus. The memory can store multiple image buffers.

Scatter-Gather DMA Controllers

The PCI/PXI-1409 uses three independent onboard direct memory access
(DMA) controllers. The DMA controllers transfer data between the
onboard SDRAM memory buffer and the PCI bus. Each of these controllers
supports scatter-gather DMA, which allows the controllers to reconfigure
on the fly. Therefore, the PCI/PXI-1409 can perform continuous image
transfers directly to either contiguous or fragmented memory buffers.

x

PCI Interface

The PCI/PXI-1409 implements the PCI interface with a National
Instruments custom application-specific integrated circuit (ASIC), the
PCI MITE. The PCI interface can transfer data at a maximum rate of
132 MB/s in bus master mode.

Genlock Circuit and SYNC Mux

The genlock circuit receives the incoming video signal and generates
PCLK, HSYNC, and VSYNC signals for use by the acquisition and control
circuitry. The 1409 device can lock to the standard RS-170/NTSC and
CCIR/PAL video signals as well as progressive scan and VGA
(640 × 480 resolution) signals. The genlock circuit on the 1409 device can
also lock to external HSYNC and VSYNC or CSYNC signals.

© National Instruments Corporation 3-3 IMAQ PCI/PXI-1409 User Manual

Chapter 3 Hardware Overview

Acquisition and Region-of-Interest (ROI) Control

The acquisition and region-of-interest control circuitry routes the active
pixels from the 10-bitADC to the onboard memory. The PCI/PXI-1409 can
perform ROI and scaling on all video lines. Pixel and line scaling transfers
certain multiples (two, four, or eight) of pixels and lines to onboard
memory.

RTSI Bus

The seven trigger lines on the RTSI bus provide a flexible interconnection
scheme between multiple PCI/PXI-1409 boards as well as between any
National Instruments DAQ or Motion device and the PCI/PXI-1409.

Digital Input/Output Circuitry

The digital input/output circuitry routes, monitors, and drives the external
trigger lines, RTSI bus lines, and camera control lines. You can use the
trigger lines to start or stop an acquisition on a rising or falling edge.
In addition, you can map onboard signals such as HSYNC, VSYNC,
ACQUISTION_IN_PROGRESS, and ACQUISITION_DONE to these
lines. The camera control lines provide a means to generate deterministic
signals for triggering cameras, strobe lights, or other timing-critical
applications. This module also contains an external clock generation
circuit. You can use this external clock as the source clock for a line scan
camera.

Acquisition Modes

The 1409 device supports five video acquisition modes.

• Standard Mode—In standard mode, the 1409 device receives an
incoming composite video signal from the external BNC or 68-pin
VHDCI connector and generates CSYNC, HSYNC, VSYNC, and
PCLK signals. The generated CSYNC signal is output on the VHDCI
connector to synchronize other image acquisition boards or cameras.

• CSYNC External Mode—In CYSNC external mode, the 1409 device
receives an incoming video signal (composite or luminance) and an
external CSYNC signal from the external connector and generates
HSYNC, VSYNC, and PCLK signals.

IMAQ PCI/PXI-1409 User Manual 3-4 ni.com

Chapter 3 Hardware Overview

• External Lock Mode—In external lock mode, the 1409 device receives
HSYNC, VSYNC, and PCLK signals from the camera and uses these
signals to acquire the video signals directly. You can also use this mode
to acquire from a line scan camera.

• External HSYNC/VSYNC Mode—In external HSYNC/VSYNC
mode, the 1409 device receives the external HSYNC and VSYNC
from the connector and internally generates the PCLK signal. The
device’s genlock circuitry locks to the external HSYNC and VSYNC
signals. You can use this mode to acquire from VGA monitors
(640

480 resolution).

x

• External HSYNC/VSYNC (HLOCK only) mode—In external
HSYNC/VSYNC (HLOCK only) mode, the 1409 device receives the
external HSYNC and VSYNC signals and internally generates the
PCLK signal. In this mode, the device’s genlock circuitry uses only the
HSYNC signal for locking. You can use this mode to acquire from
asynchronously-reset cameras which output a continuous HSYNC.

Note

Connect a FIELD signal to TRIG3 when the 1409 device is in external lock mode

with an interlaced camera.

Analog Front End Considerations

The analog front end of the IMAQ PCI/PXI-1409 device features a
calibrated gain circuit, programmable DC-restore circuit, and 10-bit ADC
asshowninFigure3-2.

10-bit/8-bit Mode

Analog

Video

The 1409 device digitizes the incoming video signal to 10 bits of resolution
at all times. In 10-bit mode, the 1409 device has four fixed, full-scale
ranges where the gain for each range is calibrated. The nominal full-scale
ranges are 0.20, 0.35, 0.70, and 1.40 V. As a result, the gain is not
continuously variable in this mode. To maintain compatibility with other
IMAQ analog devices, the 1409 device has an 8-bit mode, in which the
10-bit data from the ADC is converted to 8-bit data in the lookup table
(LUT) after gain correction and any digital filtering has occurred.

VIDEO0–, you must disconnect the BNC connector.

VIDEO<3..1>± VIDEO<3..1>± allows for a DIFF or RSE connection to video channels

1, 2, and 3. To operate in RSE mode, connect VIDEO– to GND.

PCLKIN± Use PCLKIN± when the 1409 device is in external lock mode. In this mode,

PCLKIN represents the A/D sampling clock. You can select PCLKIN to be
either TTL or RS-422 mode and program its polarity through software. In
RS-422 mode, both PCLKIN+ and PCLKIN– receive the PCLK signal.

PCLKOUT± Use PCLKOUT± when your camera requires an external pixel clock source.

The 1409 device can generate variable pixel clock frequencies between
500 kHz and 40 MHz. You can set PCLKOUT± through your software in TTL
and RS-422 modes.

HSYNCIN± Use HSYNCIN± when the 1409 device is in external lock mode. HSYNC is a

synchronization pulse produced at the beginning of each video scan line that
keeps a video monitor's horizontal scan rate in step with the transmission of
each new line. You can set HSYNCIN to be either TTL or RS-422 mode and
program its polarity through software. In RS-422 mode, both HSYNCIN+ and
HSYNCIN– receive the HSYNC signal.

VSYNCIN± Use VSYNCIN± when the 1409 device is in external lock mode. VSYNC is a

synchronization pulse generated at the beginning of each video frame that tells
the video monitor when to start a new field. You can set VSYNCIN to be either
TTL or RS-422 mode and program its polarity through software. In RS-422
mode, both VSYNCIN+ and VSYNCIN– receive the VSYNC signal.

CSYNCIN± Use CSYNCIN± when the 1409 device is in CSYNC external mode. CSYNC

is a signal consisting of horizontal sync pulses, vertical sync pulses, and
equalizing pulses only. You can set CSYNCIN to be either TTL or RS-422
mode and program its polarity through software. In RS-422 mode, both
CSYNCIN+ and CSYNCIN– receive the CSYNC signal.

CSYNCOUT CSYNCOUT is a TTL output of the internal CSYNC signal. In CSYNC

external mode, CSYNCOUT maps directly to CSYNCIN. In standard mode,
the synchronization circuitry of the 1409 device generates CSYNCOUT.
