  • Page 13: Video Input Signals

    • Triggers, and • Look-up tables (LUTs). Video Signal Types The DT3162 can acquire monochrome images from following types of standard, monochrome, composite video input signals: • RS-170/RS-343 − Standard for 60 Hz monochrome video signals. A video frame consists of 525 lines, 480 lines of which are visible.

  • Page 14: Video Input Sources

    You specify the video source (VideoSource0, VideoSource1, or VideoSource2) through software. Pin C1 of connector J1 on the DT3162 is provided for video source 0. Pin C2 of connector J1 on the DT3162 is provided for video source 1.

  • Page 15: Pixel Clock

    • Single-ended (TTL) Pixel Clock Input Source − This clock source is accessible on pin C4 of connector J1 on the DT3162. You can access this signal using the EP332 cable. Specify ExternalSource1 in software to select this pixel clock source.

  • Page 16: Triggers

    The DT3162 board supports both a software trigger and an external trigger input. The external trigger input is provided through pin 6 of connector J1 on the DT3162. You can access this signal using either EP332 cable or the Camera Interface Module.

  • Page 17: Look-Up Tables (Luts)

    Principles of Operation Look-Up Tables (LUTs) The DT3162 board provides two LUTs that you can use to change the value of an incoming pixel or affect the displayed image (also called palette matching). When the LUT gets an input pixel value, the...
  • Page 18 Video Input Signals Using software, you can select the LUT to use, and load an ASCII file or array that specifies the relationship between the pixel input values and the output values for the selected LUT.

  • Page 19: Sync Signals

    • Sync input sources, and • Sync output mode. Sync Input Sources To digitize the incoming video signal, the DT3162 board requires both a horizontal and a vertical sync input signal. The way in which the board determines the sync information depends on whether composite or variable-scan video signals are connected to the board.

  • Page 20: Variable-Scan Video Signals

    Both the EP332 cable and the CAMERA connector on the Camera Interface Module accept horizontal and vertical sync input signals. Note: Pins 1 and 2 of connector J1 on the DT3162 accept sync input signals only if sync output mode, described in the following section, is disabled.

  • Page 21: Sync Output Mode

    1 of connector J1 on the DT3162 board; the horizontal sync signal is output on pin 2 of connector J1 on the DT3162 board. The sync signals are normally output when sync output mode is enabled; however, if expose/reset is enabled, the vertical sync does not occur until the acquisition operation is started.
  • Page 22 Sync Signals • The vertical sync pulse width − Values range from 1 to 4095 lines, in increments of 1. Setting this value determines the the number of lines that the vertical sync output pulse is in its active state (determined by the sync polarity). •...

  • Page 23: Image Acquisition

    Principles of Operation Image Acquisition This section describes the following topics related to image acquisition: • Fields and frames, • Acquisition modes, • Data transfer and storage, and • Overlays. Fields and Frames You can use software to specify whether to acquire fields or frames of video information.

  • Page 24: Acquisition Modes

    Using software, you can specify one of three ways to acquire the specified fields or frames: • Single-pass synchronous mode − The DT3162 board acquires a specified number of frames or fields, saves the corresponding region on interest (ROI) in each frame/field to buffers in memory, then stops.
  • Page 25 ROIs have been acquired, if you wish, using software. Specify SinglePassAsync in software to use this mode. • Continuous asynchronous mode − The DT3162 board continuously acquires an unlimited number of fields or frames and saves the corresponding ROIs to buffers in memory until you stop the acquisition.

  • Page 26: Data Transfer And Storage

    (maximum 132 MB/s). Data is stored in monochrome format, or 8-bits per pixel. Overlays For the DT3162 board, you can use software to add overlays, such as text or graphics, on top of another displayed image that was acquired. Overlays are useful for creating animation or to display...

  • Page 27: Video Area

    The total video area is as wide as the total pixels per line (the entire area between two consecutive horizontal sync signals) and as tall as the total lines per frame. You can use software to define the total video area for the DT3162 board. Table 1 lists the settings you can program.

  • Page 28: Active Video Area

    Using software, you can define the active area for the DT3162 board. The following sections describe how to use the settings of the board to define the horizontal and vertical components of the active video area.

    You can access the expose/reset signal, which is provided on pin 7 of connector J1 on the DT3162 board, using the EP332 cable or the CAMERA connector on the Camera Interface Module.
  • Page 36 Expose/Reset Signal Note: The expose/reset stop line plus the vertical sync delay must be less than or equal to 65535. The qualified acquisition trigger can be an internal (software) trigger if you are acquiring one frame only, or an external trigger (ExternalForEach) if you are acquiring more than one frame.

  • Page 37: Strobe Output Signal

    You can generate a strobe output pulse to control lighting for a progressive scan camera. The strobe output pulse is provided on pin 12 of connector J2 on the DT3162 board. To access this signal, use the STP15 screw terminal panel and EP337 cable.
