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.  
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.

Chapter 1  
Introduction  
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  
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.  
NI-IMAQ also provides the interface path between the NI 1410 and  
LabVIEW, LabWindows/CVI, or a text-based programming  
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.  
National Instruments Application Software  
This section describes the National Instruments application software  
packages you can use to analyze and process the images you acquire with  
the NI 1410.  
Vision Builder for Automated Inspection  
NI Vision Builder for Automated Inspection (AI) is configurable machine  
vision software that you can use to prototype, benchmark, and deploy  
applications. Vision Builder AI does not require programming, but is  
scalable to powerful programming environments.  
Vision Builder AI allows you to easily configure and benchmark a  
sequence of visual inspection steps, as well as deploy the visual inspection  
system for automated inspection. With Vision Builder AI, you can perform  
powerful visual inspection tasks and make decisions based on the results of

individual tasks. You also can migrate the configured inspection to  
LabVIEW, extending the capabilities of the applications if necessary.  
Vision Development Module  
The Vision Development Module is an image acquisition, processing, and  
analysis library of more than 270 functions for the following common  
machine vision tasks:  
Pattern matching  
Particle analysis  
Gauging  
Taking measurements  
Grayscale, color, and binary image display  
You can use the Vision Development Module functions individually or  
in combination. With the Vision Development Module, you can acquire,  
display, and store images, as well as perform image analysis, and  
processing. Using the Vision Development Module, imaging novices and  
experts can program the most basic or complicated image applications  
without knowledge of particular algorithm implementations.  
As a part of the Vision Development Module, NI Vision Assistant is an  
interactive prototyping tool for machine vision and scientific imaging  
developers. With Vision Assistant, you can prototype vision applications  
quickly and test how various vision image processing functions work.  
Vision Assistant generates a Builder file, which is a text description  
containing a recipe of the machine vision and image processing functions.  
This Builder file provides a guide you can use for developing applications  
in any ADE, such as LabWindows/CVI or Visual Basic, using the Vision  
Assistant machine vision and image processing libraries. Using the  
LabVIEW VI creation wizard, Vision Assistant can create LabVIEW VI  
block diagrams that perform the prototype you created in Vision Assistant.  
You then can use LabVIEW to add functionality to the generated VI.

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.

Chapter 2  
Hardware Overview  
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.  
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.

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.

Chapter 2  
Hardware Overview  
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.

Figure 2-2. NI 1410 Analog Front End  
10-Bit/8-Bit Mode  
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.  
Clamping  
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.

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  
verify that the W1 jumper is in place. Next, use the 2 m BNC cable shipped  
with the NI 1410, or another 75 Ω BNC cable, to connect to the BNC  
connector. If you are using a BNC connection, the VIDEO0 connection  
on the 68-pin VHDCI I/O connector must be left open.  
Refer to Figure 3-1 for the location of the NI 1410 W1 jumper and the  
connectors discussed in this chapter.

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>  
PCLKIN  
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.  
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  
VSYNCIN  
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.  
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.

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>  
DGND  
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 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.
