    Cv-a11 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 wid...

    Cv-a11 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, t...

    Cv-a11 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 int...

    Cv-a11 6.4. External trigger modes this camera has 6 external asynchronous trigger modes, which can be set by rs-232c commands. 1. Edge pre-select mode.Tr=1 pre-selected exposure. (sm=0, sm=1) 2. Pulse width control mode. Tr=2 pulse width controlled exposure. (hc=0, hc=1) 3. Frame delay read out mod...

    Cv-a11 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). If the polarity of this pulse is r...

  • Page 11

    Cv-a11 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...

    Cv-a11 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 exposu...

    Cv-a11 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. Vd pulse, which aga...

  • Page 14

    Cv-a11 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 s...

    Cv-a11 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 highlig...

    Cv-a11 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. Fig. 23. Partial scanning. The partial scann...
