Page 3 - Standard Composition
CV-A1-20 1. General The CV-A1-20 is a monochrome progressive scan 1/2” CCD camera with 1.4 Megapixel resolution. CV-A1-20 is identical to CV-A1, but the pixel frequency is 20 MHz instead of 28.636 MHz. It is designed for automated inspection, featuring a small housing and a wide range of unique func...

CV-A1-20 Binning mode BI is a function where the signal charge from 2 or more adjacent pixels are added together and read out as one pixel. A resulting full frame with lower resolution can be read out with a higher rate. By adding 2 pixels together, the sensitivity is doubled. The CV-A1-20 has both ...

CV-A1-20 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 i...

CV-A1-20 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 m...

CV-A1-20 6.5. Edge Pre-select Mode The exposure starts at the first HD pulse after the trigger leading edge. It stops and is read out after the duration of the shutter time selected. It can be the first 9 step in normal or 1023 steps in programmable shutter. SM=0 or SM=1. Shutter selections SH ≥ 10 ...

CV-A1-20 6.7. Frame-delay read out Mode In this mode the exposure starts from the leading edge of the trigger pulse. It stops at the trailing edge of the trigger pulse. The accumulation can be either H synchronous or H asynchronous. HC=0 or HC=1. In H synchronous mode the accumulation starts at the ...
