NI 1409 devices have high-resolution, 10-bit digitization for cameras and sensors that offer 60 dB dynamic range. In addition, you can easily configure the NI 1409 Series to work with standard monochrome cameras (RS-170 or CCIR), slow or variable rate pixel clock cameras, double-speed progressive scan cameras, and analog line-scan cameras. 10-Bit Image Acquisition Measurement-Quality Image Acquisition with Calibration NI 1409 devices are gain calibrated and delivered with a calibration certificate. Calibration ensures repeatable, consistent image acquisition for your machine vision and scientific imaging applications. INFO CODES Many high-resolution analog monoFor more information chrome cameras have dynamic range or to order products online, visit ni.com/info greater than 48 dB, which means that and enter: the camera has resolution capabilities pci1409 greater than 8-bit or 256 gray scales. pxi1409 For these high-resolution cameras, you should use an image acquisition BUY ONLINE! device that offers comparable or greater resolution. The NI 1409 Series works with the highest quality monochrome cameras and delivers up to 60 dB of dynamic range, which corresponds to 10 bits or 1,024 gray scales. With NI 1409 devices, you have the option to acquire in 8-bit or 10-bit mode at very high rates, such as 60 frames/s with double-speed progressive scan cameras. Vision Interchange Cameras with NI-IMAQ NI-IMAQ driver software for image acquisition can scale between many types of cameras and acquisition methods. With NI-IMAQ, you can begin by using a low-cost RS-170 camera and image acquisition device and then upgrade to a faster, higher-resolution camera and acquisition hardware with minimal software changes. Because NI-IMAQ driver software uses one set of function calls for a wide variety of cameras, there is no need to rewrite your software. Variable Scan and Nonstandard Video With NI 1409 devices, you can acquire images from nonstandard video, such as analog line-scan and variable-scan devices with pixel clocks that range from 2 to 40 MHz. The NI 1409 devices work with double-speed (60 frames/s) progressive scan or noninterlaced monochrome cameras from vendors such as Sony and JAI.

This utility is an interactive tool for setting the camera type (RS-170, CCIR, NTSC, and PAL), programmable ROI, aspect ratio, and antichrominance filter. Use this interactive utility to set up acquisition from noninterlaced progressive-scan cameras and to create your own camera configurations for nonstandard video. Use the external lock feature to set variable-scan acquisition for microscopes and other sources that generate their own pixel clock and horizontal and vertical synchronization signals. DAQ Synchronization The RTSI bus or PXI trigger bus provide a flexible synchronization scheme between any National Instruments IMAQ, DAQ, or motion device and your PCI-1409 or PXI-1409, respectively. Trigger Control and Mapping Circuitry The trigger control and mapping circuitry routes, monitors, and drives the external and RTSI or PXI trigger bus lines. You can configure each of these lines to start or stop acquisition on a rising or falling edge, or use each line as digital I/O. You can also map the lines to onboard status values (CSYNC, Acquisition in Progress, and Acquisition Complete). Image Acquisition Performance Gains with Partial Image Scanning For improved throughput and processing bandwidth, the acquisition and ROI control circuitry monitors the incoming video signal and routes the active pixels to the FIFO. In addition to being able to digitize an entire frame, an NI 1409 can perform pixel and line scaling (decimation) and ROI acquisition. With pixel and line scaling, multiples (2,4,8) of pixels and/or lines can be transferred to the PCI bus. Using ROI acquisition, you select an area in the acquisition window that will be transferred to the PCI bus. Antichrominance and Lowpass Filter NI 1409 devices have an antichrominance filter, which can remove chrominance information from a color video signal. There are two software selectable antichrominance filters – one for NTSC color -coded signals (a 3.58 MHz notch filter), and another for PAL color -coded signals (a 4.43 MHz notch filter). Use the lowpass filter at 9 MHz to remove unwanted noise. 10-Bit A/D and Look-Up Table (LUT) An A/D converter performs the image digitization, the result of which passes to a 1,024 by 10 RAM LUT. You can configure the LUT to implement simple imaging operations, such as gamma manipulation, contrast enhancement, data inversion, or any nonlinear transfer function. Hardware PCI Interface The PCI bus is the electrical interface for both NI PCI-1409 and NI PXI-1409. The PCI interface, implemented with the National Instruments MITE ASIC, can transfer data at a maximum sustained rate of 100 Mbytes/s in master mode to maximize the use of the available bandwidth. The interface logic ensures that the NI 1409 meets the loading, driving, and timing requirements of the PCI specification. Vision Programmable Gain and Offset The NI 1409 has programmable gain and offset circuitry for optimizing the input signal range. VCR Circuitry Scatter-Gather DMA Controllers An NI 1409 has three independent onboard DMA controllers. The DMA controllers can transfer data between the Host memory and the onboard FIFO via the PCI bus. Each of these controllers performs scatter-gather DMA, which means the DMA controller can reconfigure on the fly, and thus perform continuous image transfers to either contiguous or fragmented buffers. Because many commercial and home VCRs have noisy synchronization signals or no synchronization at all, VCRs are difficult to use with most image acquisition hardware. However, with its built-in circuitry and logic for handling video signals from VCRs, the NI 1409 can acquire monochrome images from VCRs. Digital I/O The NI 1409 Series includes four general-purpose digital input/output lines for general-purpose triggering and pulse generation capabilities. In addition, each NI 1409 includes four digital output lines for lighting, shutter, camera control, and pulse generation. Onboard Memory An NI 1409 has 16 MB of onboard memory used to temporarily store the image being transferred to the PCI bus. With 16 MB, you can buffer large images during image acquisition. 592 National Instruments • Tel: (800) 433-3488 • Fax: (512) 683-9300 • info@ni.com • ni.com 591-593 4 Channel Mono 10/28/08 1:35 PM Page 593 4-Channel Monochrome Image Acquisition 4-Channel Monochrome Image Acquisition BNC Connector The BNC connector supplies an immediate connection to the VIDEO0 input of the NI 1409.
