  • Page 5: Introduction To The 6M18 Camera

    The 6M18 is an outstanding performer in fast, very high resolution applications. True 12 bit performance provides up to 4096 distinct gray levels—perfect for applications with large interscene light variations. The low-noise, digitized video signal also makes the camera an excellent choice where low contrast images must be captured in challenging applications. DALSA 03-32-10017-03...

    “Programmed Integration/External Trigger Mode.” • You can also have the camera integrate as long as an asynchronous TTL pulse is held high. This pulse will therefore control both integration time and frame rate. This is also known as “External Integrate Mode.” DALSA 03-32-10017-03...

  • Page 31 The camera is “armed” when the read out of the acquired frame is completed. No additional rising edges, or triggers, should be allowed during the image acquisition or frame read out.
