IMAQ System document and your NI-IMAQ release notes. PCI-1411 You can install the PCI-1411 in any available PCI expansion slot in your computer. However, to achieve the best noise performance, you should leave as much room as possible between the PCI-1411 and other boards and hardware. - Page 19 Touch the metal part of the power supply case inside the computer to discharge any static electricity that might be on your clothes or body. Line up the PCI-1411 with the BNC connectors near the cut-out on the back panel. Slowly push down on the top of the PCI-1411 until its card-edge connector is resting on the expansion slot receptacle.

Page 21: Video Decoder
Chapter 3 Hardware Overview Video Decoder The PCI/PXI-1411 supports NTSC and PAL video standards in either composite or S-Video format. The onboard video decoder converts the incoming video signal to Red, Green, and Blue (RGB) data and passes this data to the color-space processor for further processing. The video decoder also allows you to control numerous parameters to optimize an acquisition. -

Page 23: Bus Master Pci Interface
Chapter 3 Hardware Overview Bus Master PCI Interface The PCI/PXI-1411 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 Mbytes/s in bus master mode. The PCI/PXI-1411 can generate 8-, 16-, and 32-bit memory read and write cycles, both single and multiple. - Page 24 • • © National Instruments Corporation Region of interest—The PCI/PXI-1411 uses a second level of active pixel and active line regions for selecting a region of interest. When you disable the region-of-interest circuitry, the board stores the entire acquisition window into with onboard or system memory. However, when you enable the region-of-interest circuitry, the board acquires only a selected subset of the image frame.
