Introduction

This chapter describes the NI PCI-1410 (NI 1410) device and its software
programming options.

About the NI 1410 Device

The NI 1410 is a high-accuracy, monochrome image acquisition device for
PCI that supports RS-170, CCIR, NTSC, and PAL video standards, as well
as nonstandard cameras from any of four input sources. The NI 1410
features a 10-bit analog-to-digital converter (ADC) that converts video
signals to digital formats. The NI 1410 acquires images in real time and
stores them in onboard frame memory or transfers them directly to system
memory.

The NI 1410 is easy to install and configure. The NI 1410 ships with
NI Vision Acquisition Software, which includes NI-IMAQ, the National
Instruments driver software you can use to directly control the NI 1410 and
other National Instruments image acquisition devices. With NI-IMAQ, you
can quickly and easily start the applications without having to program the
device at the register level.

1

As a stand-alone device, the NI 1410 supports four general-purpose control
lines that are configurable to generate precise timing signals for controlling
camera acquisition. The NI 1410 also supports four video sources and four
external I/O lines to use as triggers or digital I/O lines.

Easily synchronizing several functions to a common trigger or timing event
is a common challenge with image acquisition devices. The NI 1410 uses
its Real-Time System Integration (RTSI) bus to solve this problem. The
RTSI bus uses the National Instruments RTSI bus interface and ribbon
cable to route additional timing and trigger signals between the NI 1410
and National Instruments DAQ, Motion Control, or other image acquisition
devices. The RTSI bus can even synchronize multiple image acquisition
hardware captures.

For detailed specifications of the NI 1410, refer to the Specifications
section of Getting Started with the NI PCI-1410.

NI PCI-1410 User Manual 1-2 ni.com

NI-IMAQ Driver Software

The NI 1410 ships with NI Vision Acquisition Software, which includes
the NI-IMAQ driver software. NI-IMAQ has an extensive library of
functions—such as routines for video configuration, continuous and single
shot image acquisition, memory buffer allocation, trigger control, and
device configuration—you can call from the application development
environment (ADE). NI-IMAQ handles many of the complex issues
between the computer and the image acquisition device, such as
programming interrupts and camera control.

NI-IMAQ performs all functions required for acquiring and saving images
but does not perform image analysis. For image analysis functionality, refer
to the National Instruments Application Software section of this chapter.

Chapter 1 Introduction

NI-IMAQ also provides the interface path between the NI 1410 and
LabVIEW, LabWindows
environment. The NI-IMAQ software kit includes a series of libraries for
image acquisition for LabVIEW, LabWindows/CVI, and Measurement
Studio, which contains libraries for Microsoft Visual Basic.

NI-IMAQ features both high-level and low-level functions. Examples
of high-level functions include the sequences to acquire images in
multi-buffer, single-shot, or continuous mode. An example of a low-level
function is configuring an image sequence, since it requires advanced
understanding of the image acquisition device and image acquisition
principles.

Hardware Overview

This chapter describes the features of the NI PCI-1410 device and includes
information about acquisition modes, analog front-end considerations, and
clamping.

Functional Overview

The NI 1410 features a flexible, high-speed data path optimized for the
acquisition and formatting of video data from analog cameras. The NI 1410
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 NI 1410 digitizes analog video signals to 8 or 10 bits of resolution at
sampling frequencies up to 40 MHz.

The NI 1410 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 onboard
memory when necessary. The NI 1410 includes four external triggers,
four camera control signals, seven RTSI bus triggers, and four video
synchronization signals.

The 10-bit ADC digitizes the conditioned video signal.

NI PCI-1410 User Manual 2-2 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 1,024 × 10-bit lookup table (LUT). You can configure the LUT
to implement simple imaging operations such as contrast enhancement,
data inversion, gamma correction, or other user-defined transfer functions.

Onboard Memory

The NI 1410 has 16 MB of SDRAM for temporarily storing image data
being transferred to the system memory through the PCI bus. The memory
can store multiple image buffers.

Scatter-Gather DMA Controllers

The NI 1410 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. This functionality enables the NI 1410 to perform continuous
image transfers directly to either contiguous or fragmented memory
buffers.

Chapter 2 Hardware Overview

PCI Interface

The NI 1410 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 NI 1410 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 NI 1410 also can
lock to external HSYNC and VSYNC or CSYNC signals, as well as
additional nonstandard formats.

© National Instruments Corporation 2-3 NI PCI-1410 User Manual

Chapter 2 Hardware Overview

Acquisition and Region-of-Interest Control

The acquisition and region-of-interest (ROI) control circuitry routes
the active pixels from the 10-bit ADC to the onboard memory. The NI 1410
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 image acquisition devices, as well as between
National Instruments DAQ or Motion Control devices.

Digital Input/Output Circuitry

The digital input/output (I/O) 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.
You also 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.

Note The NI 1410 does not support pixel clock output on the trigger lines.

Acquisition Modes

The NI 1410 supports the following four video acquisition modes:

• Standard Mode—In standard mode, the NI 1410 receives an

incoming composite video signal from the external BNC or 68-pin
VHDCI connector and generates CSYNC, HSYNC, VSYNC, and
PCLK signals. The VHDCI connector outputs the generated CSYNC
signal to synchronize other image acquisition devices or cameras.

• CSYNC External Mode—In CYSNC external mode, the NI 1410

receives an incoming video signal (composite or luminance) and an
external CSYNC signal from the external connector and generates
HSYNC, VSYNC, and PCLK signals.

• External Lock Mode—In external lock mode, the NI 1410 receives

HSYNC, VSYNC, and PCLK signals from the camera and uses these
signals to acquire the video signals directly. You can use this mode to
acquire from a line scan camera.

NI PCI-1410 User Manual 2-4 ni.com

• External HSYNC/VSYNC (HLOCK only) Mode—In external

HSYNC/VSYNC (HLOCK only) mode, the NI 1410 receives the
external HSYNC and VSYNC signals and internally generates the
PCLK signal. In this mode, the NI 1410 genlock circuitry uses only the
HSYNC signal for locking. You can use this mode to acquire from
asynchronously reset cameras that output a continuous HSYNC.

Analog Front End Considerations

The analog front end of the NI 1410 features a calibrated gain circuit,
programmable DC-restore circuit, and 10-bit ADC as shown in Figure 2-2.

Digital Gain

Correction,

Filtering, and LUT

The NI 1410 always digitizes the incoming video signal to 10 bits of
resolution. In 10-bit mode, the NI 1410 has four fixed, full-scale ranges for
calibrating the gain for each range. Because the nominal full-scale ranges
are 0.20, 0.35, 0.70, and 1.40 V, the gain is not continuously variable in
this mode. To maintain compatibility with existing acquisition code
and processing algorithms used with other analog image acquisition
devices, the NI 1410 has an 8-bit mode that converts the 10-bit data from
the ADC to 8-bit data in the LUT after gain correction and any digital
filtering has occurred.

The NTSC camera file sets the default values of Clamp Start and Clamp
Stop to 106 and 116, respectively. These settings place the clamp pulse,
which restores the DC level of the video signal, between the color burst
signal and the beginning of active video. Because some cameras deviate
from the exact timing required by the NTSC standard, the clamping pulse
may intersect either the color burst or the active video portions of the
signal. If this occurs, an acquired image may appear to have dark and light
bands, as in the following image.

To prevent this problem, open Measurement & Automation Explorer
(MAX) and navigate to the Advanced tab of the camera file property page.
Use the following guidelines to adjust the Clamp Start and Clamp Stop
values until the image is corrected:

• Minimum Clamp Start is 100

• Maximum Clamp Stop is 120

• Difference between Clamp Start and Clamp Stop is at least 10

Signal Connections

This chapter describes cable connections for the NI PCI-1410 device.

Video Input Channels

The video input channels for the NI 1410 support two input
modes—referenced single-ended (RSE) and differential (DIFF). A
channel configured in DIFF mode uses two inputs. One input connects to
the positive terminal, and the other connects to the negative terminal. A
channel configured in RSE mode uses one input, which connects to the
positive terminal. The negative input is internally tied to ground.

BNC Connector

The BNC external connector supplies an immediate connection (RSE mode
only) to the NI 1410 VIDEO0 input. To connect a camera to VIDEO0, first

Digital I/O Connector Signal Connection Descriptions

Table 3-1 describes each signal connection on the 68-pin VHDCI
connector.

Table 3-1. I/O Connector Signals

Signal Name Description

VIDEO0± VIDEO0± allows for a DIFF or RSE connection. To operate in RSE mode,

you must connect VIDEO0– to DGND. When you use VIDEO0+ or
VIDEO0–, you must disconnect the video signal from the BNC connector. To
operate in DIFF mode, remove attached W1 jumper.

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<3..1>– to DGND.

PCLKIN± Use PCLKIN± when the NI 1410 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.

HSYNCIN± Use HSYNCIN± when the NI 1410 is in external lock mode or external

HSYNC/VSYNC (HLOCK only) mode. HSYNC is a synchronization pulse
produced at the beginning of each video scan line that keeps the video monitor
horizontal scan rate in step with the transmission of each new line. You can set
HSYNCIN for 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 NI 1410 is in external lock mode or external

HSYNC/VSYNC (HLOCK only) 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 NI 1410 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 NI 1410 generates CSYNCOUT.

Chapter 3 Signal Connections

Table 3-1. I/O Connector Signals (Continued)

Signal Name Description

TRIG<3..0> Triggers<3..0> are TTL I/O lines used to start or stop an acquisition or output

an acquisition status. You can program the triggers to be rising- or falling-edge
sensitive. You also can program the triggers to be programmatically asserted
or unasserted, which is similar in function to a digital I/O line, or to contain
specific pulse widths or internal status signals by using the onboard events.

CTRL<3..0>± Use the control lines on the NI 1410 to control camera features and timing

information, such as generating integration or shutter pulses. You can generate
either static or dynamic signals and either TTL or differential signals on these
lines.

DGND DGND is a direct connection to digital GND on the NI 1410.

CHASSIS_GND CHASSIS_GND is a direct connection to the computer’s chassis, which is

grounded through the power cord.
