CV-A11 1. Gener al 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 all ow functions such as pulse width controlled shutter, programmable shutter sp[...]

CV-A11 6. F unctions and Oper ations Apart from the standard continuous operation, t h e CV-A11 features three external asynchronous trigger modes (edge pre-select, pulse width cont rolled and start/stop) and a special frame-delay readout mode. Long integration ti me mode is also supp orted. In addition, the CV-A11 also provide s a partial scan rea[...]

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, th e camera will synchronize to it. If no external sync signals are applied, the camera will oper ate with its internal x-tal controlled sync. The camera scanning[...]

CV-A11 6.4. External Trigger Modes This camera has 6 external asynchr onous trigger modes, which can be s et 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, H C=1) 3. Frame Delay read out mode. TR=3 PWC exposure read out by ext. VD. (HC=0[...]

CV-A11 6.5. Edge Pre-select Mode An external trigger pulse initiates the capture (inp ut 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 reversed, the camera can be configured to correct [...]

CV-A11 6.6. Pulse Width Control Mode The leading edge of the trigger pulse initiates the capture. The exposure time (acc umulation 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 d u[...]

CV-A11 6.7. Frame-delay read out Mode This mode allows simultaneous c apture of multiple camera using a common external trigger pulse subsequent multiplexed (sequential) readou t using a single input frame grab ber, as the user has control over when the image is read ou t from the CCD sensor. The exposure starts at the falling edge of the ext. trig[...]

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 ex posure starts after input of the first ext. VD pulse, and ends after the next input of the ne xt ext. VD pulse, which ag ain starts a new exposure. The long time exposur[...]

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 t he 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 secon d. The Start/Stop mode is a continuous mode [...]

CV-A11 6.10. Smearless Mode This mode will reduce the unwant ed smear signal from a highlighted scene when a short exposure time is used. The trigger mode is like edge pre-se lect, 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 smea[...]

CV-A11 6.11. Partial scan readout mode This mode allows increased frame rate, as only a selected number of lines are re ad out. The vertical resolution is reduced as ou tlined below. Partial scan will operate in normal continuous mode and all trigger modes. Fig. 23. Partial scanning. The partial scanning settings are as follows: Readout format Fram[...]

AS, AGC Switch The video gain can be set to AGC or manual . In AGC mode the video level is kept constant by the automatic gain control circuit within a 12 dB range. Normal 700 mVpp ± 30 mV. The level can be a[...]

CV-A11 10. Appendix 10.1. CV-A11 emulating CV-M10 interfacing The CV-A11 has a slightly different pin configu r ation on the 12-pin Hirose connector, compared to the M-series. This new configura tion is compliant to the EIA-J standa rd. This means, however, that the CV-A11 is not completely backward co mpatible with the CV-M10, CV-M40, etc in all c[...]
