    1. General The CV-A11 is a monochrome progressive scan 1/3” CCD cameras, designed for automated inspection application, featuring an extremely small housing and a wide range of unique functions. The asynchronous trigger can be set to work in several modes, to allow functions such as pulse width controlled shutter, programmable shutter speed and long time integration.

    EEN will be low all the time in normal continous mode (TR=0), if the selected exposure time is longer than the frame readout time. For schematic diagram of the input and output circuit alternative settings refer to 5.3. CV-A11 Pin configuration is compatible with EIAJ standard Pin no.

    5.3. Input and Output Circuits In the following schematic diagrams the input and output circuits for video and timing signals are shown. For alternative connections refer to “10.1. CV-A11 emulating CV-M10 interfacing.” Jumper settings are shown as for factory default.

  • Page 7: Functions And Operations

    6. Functions and Operations Apart from the standard continuous operation, the CV-A11 features three external asynchronous trigger modes (edge pre-select, pulse width controlled and start/stop) and a special frame-delay readout mode. Long integration time mode is also supported. In addition, the CV-A11 also provides a partial scan readout function.

  • Page 8: Input-Output Of Hd/Vd Signals

    6.2. Input-output of HD/VD Signals In the default setting the camera will accept external HD/VD signals on pin 6 and 7 of the 12 pin Hirose connector. If external HD/VD is applied, the camera will synchronize to it. If no external sync signals are applied, the camera will operate with its internal x-tal controlled sync.

  • Page 9: External Trigger Modes

    6.4. External Trigger Modes This camera has 6 external asynchronous trigger modes, which can be set by RS-232C commands. Edge Pre-select Mode.TR=1 Pulse Width Control Mode. TR=2 Frame Delay read out mode. TR=3 Long Time Exposure Mode. TR=4 Start/stop Mode. TR=5 Smearless Read out mode.

  • Page 10: Edge Pre-Select Mode

    6.5. Edge Pre-select Mode An external trigger pulse initiates the capture (input on pin 11 of the 12-pin Hirose connector or pin 5 of the 6-pin Hirose). The leading edge of the trigger pulse initiates the exposure (this is a falling edge if factory default).

  • Page 11: Pulse Width Control Mode

    6.6. Pulse Width Control Mode The leading edge of the trigger pulse initiates the capture. The exposure time (accumulation time) is governed by the duration of the trigger pulse. If the polarity of this pulse is reversed, the camera can be configured to correct for it. The exposure time range is 1.5H to 1000H (shortest and longest pulse duration).

  • Page 12: Frame-Delay Read Out Mode

    6.7. Frame-delay read out Mode This mode allows simultaneous capture of multiple camera using a common external trigger pulse subsequent multiplexed (sequential) readout using a single input frame grabber, as the user has control over when the image is read out from the CCD sensor. The exposure starts at the falling edge of the ext.

  • Page 13: Long Time Exposure Mode

    6.8. Long Time Exposure Mode The exposure time is the interval between 2 ext. VD pulses sent to the VD input of the camera (Pin No. 7 of the 12-pin Hirose connector). The exposure starts after input of the first ext. VD pulse, and ends after the next input of the next ext.

  • Page 14: Start/Stop Mode

    6.9. Start/Stop Mode The exposure time is controlled by the interval between the ext. trigger and the ext. VD signal. The exposure starts at the first HD pulse after the falling edge of the ext. trigger, and stops at the rising edge of the VD pulse. The range can be between 1/30 to 1/10,000 second. The Start/Stop mode is a continuous mode where the VD signal must be given continuously.

  • Page 15: Smearless Mode

    6.10. Smearless Mode This mode will reduce the unwanted smear signal from a highlighted scene when a short exposure time is used. The trigger mode is like edge pre-select, but a fast dump readout is performed before the active accumulation is started. It will remove the smear over the highlighted parts in the image, but there is still smear left below highlighted areas.

  • Page 16: Partial Scan Readout Mode

    6.11. Partial scan readout mode This mode allows increased frame rate, as only a selected number of lines are read out. The vertical resolution is reduced as outlined below. Partial scan will operate in normal continuous mode and all trigger modes. The partial scanning settings are as follows: Readout format Frame rate Effective lines...

    M-series. This new configuration is compliant to the EIA-J standard. This means, however, that the CV-A11 is not completely backward compatible with the CV-M10, CV-M40, etc in all cases (depending on the cable configuration). The table below shows how to change the pin configuration, by changing internal solder jumpers.
