  • Page 19: Supported Software

    • DT3155 Device Driver − This software is provided on the Imaging OMNI CD, which is shipped with the board. You must install this device driver to use a DT3155 board with any of the supported software packages or utilities. Refer to the DT3155 Getting Started Manual for information on installing the device driver.

  • Page 20: Accessories

    Accessories The following optional accessories are available for the DT3155 board: • EP306 − To connect the DT3155 board to your video input source, you need either an EP306 cable (available from Data Translation) or a user-designed cable. The EP306 is a 5-foot cable with a 15-pin, D-shell connector on one end and 14 BNC connectors on the other end.

  • Page 23: Video Input Signals

    • Pixel clock, and • External trigger. Video Formats The DT3155 can acquire monochrome images in the following standard, composite video formats: • RS-170 − Standard for 60 Hz monochrome video signals. A video frame consists of 525 lines, 480 lines of which are visible.

  • Page 24: Video Input Channels

    For ease of use, both of these voltages are measured at the camera's output. The DT3155 supports a minimum black level of + 1.275 mV and a maximum black level of 306 mV, in increments of 1.195 mV. By default, the black level is + 53.855 mV for 60 Hz and 1.275 mV for...

  • Page 25: Pixel Clock

    (0 V) should not be less than 500 mV. Pixel Clock The DT3155 generates a 12.5 MHz pixel clock signal for 60 Hz image formats and a 15 MHz pixel clock signal for 50 Hz image formats. Using the Digital Clock Sync Circuitry, which has no more than ±5.0 ns jitter, the DT3155 board synchronizes the pixel clock to the...

  • Page 26: Input Look-Up Table

    Chapter 2 Input Look-Up Table The board’s input look-up table (ILUT) allows you to change the value of an incoming pixel. The digital value of each 8-bit pixel passes from the ADC into the 256 x 8-bit ILUT on the board. The ILUT retrieves the output value for that particular pixel and passes the output value to the software scaler.

  • Page 27: Sync Signals

    • Sync signal selection, and • Sync signal insertion (Sync Sentinel). Sync Signal Selection To digitize the incoming video signal, the DT3155 frame grabber requires both horizontal and vertical sync signals. The DT3155 board determines this sync information from the current input channel or from one of the unused composite video input signals on the board.

  • Page 28: Sync Signal Insertion (Sync Sentinel)

    The Sync Sentinel circuitry provides sync continuity for the DT3155 board. The Sync Sentinel is especially useful for noisy input sources, such as VCRs, where the DT3155 frame grabber may interpret a noise spike in the video signal as a horizontal or vertical sync, or the board may miss some syncs that are below the threshold.

  • Page 29: Video Area

    Principles of Operation Video Area The total video area is a complete set of horizontal and vertical input lines from which you extract the active video area and the frame within the active video area. The total video area includes all parts of the signal, including nonvisual portions such as horizontal and vertical blanking information.

  • Page 30: Horizontal Video Signal

    Pixel measurements are relative to the horizontal reference point, which is defined as the beginning of the horizontal sync. The settings for the horizontal video signal are fixed on the DT3155 board.

  • Page 31: Vertical Video Signal

    Line measurements are relative to the vertical reference point, which is defined as the beginning of the vertical sync. Lines themselves are measured in terms of pixels. The settings for the vertical video signal are fixed on the DT3155 board.

  • Page 32: Frame (Region Of Interest)

    The width of the frame is the number of pixels per line of video; this is fixed at 768 for 50 Hz and 640 for 60 Hz on the DT3155 board. The height of the frame is the number of lines per field; this is fixed at 576 for 50 Hz and 480 for 60 Hz on the DT3155 board.

  • Page 33: Types Of Frames

    Figure 4: Spatial Relationship of Video Signal Types of Frames The DT3155 board can acquire interlaced frames only. The video signal is defined as two consecutive fields, where the start of each field is identified by the falling edge of the vertical sync.

  • Page 34: Scaling Frames

    • Interlaced frames, starting on the next odd field, or • Interlaced frames, starting on the next field (odd or even). Scaling Frames You cannot reduce or enlarge (scale) the image on the DT3155 board. The scale factor is fixed at 1. Frame Storage Mode You can store the frame data for DT3155 board in monochrome mode only, or 8-bits per pixel.

  • Page 35: Passthru Operations

    Principles of Operation Passthru Operations In a passthru operation, the DT3155 board continuously captures and displays video data until you stop the operation. Typically, you use passthru to view images (in as close to real time as possible for the configuration and passthru method chosen) for the purpose of focusing or positioning the camera.

  • Page 36: Continuous-Acquire Passthru Mode

    (see page 23). Continuous-Acquire Passthru Mode The DT3155 board supports asynchronous, continuous-acquire passthru mode. Since it is asynchronous, the operation starts but gives control to you immediately, allowing you to perform other operations while data is acquired and/or displayed.

  • Page 37: Source Origin

    This mode also has a synchronization mechanism using a WIN32 event object. Using this object, you can synchronize your application with the DT3155 board to process data as it becomes available. A continuous-acquire passthru operation continues until you stop it using software.

  • Page 38: Passthru Lut

    Chapter 2 Passthru LUT It is assumed that the data passed to display memory is 8 bits/pixel. By default, passthru operations load the Windows system palette with 128 grayscale RGB values for display and use the default passthru LUT of 256 monotonically increasing grayscales. Using software, you can modify the 256-position passthru LUT so that false coloring is used.

  • Page 39: Acquisition Modes

    Using the DT3155, you can acquire single frames to an area in system memory that was either allocated to the DT3155 Device Driver during system startup (called device memory) or provided by you (called host memory).

  • Page 40: Digital Output Signals

    Chapter 2 Digital Output Signals The DT3155 board provides eight digital output lines on pins 1 to 3 and 9 to 13 on the board’s J1 connector. These digital output signals are simple register-driven, TTL-level signals that you can use for any purpose, such as controlling or actuating external devices.
