    Connecting to Lighting Devices The Power and I/O connector has a specialized analog dimmer output intended to be used with the Advanced Illumination Inline Control System 3 (ICS 3) or ICS 3S for continuous or strobed lighting operations. Related Information Triggering on page 20 External Trigger...

  • Page 14: Wiring The Isolated Inputs

    The isolated inputs on the ISC-178x have a built-in current-limiting circuit. The isolated inputs do not require a current-limiting resistor. Refer to the specifications of the connected output device to determine if a resistor is needed to limit the output current. ISC-178x User Manual | © National Instruments | 13...

  • Page 15: Wiring The Isolated Outputs

    Figure 11. Wiring an Isolated Input to a Sinking Output External Power Supply – Iso In ISC-178x Sinking Output Device Wiring an Isolated Input to a Sourcing Output The following figure shows how to wire the isolated inputs with a sinking configuration to a sourcing output.
  • Page 16 A resistor may not be needed if the current is sufficiently limited by the input device. Related Information Choosing a Pull-up Resistor on page 16 ISC-178x User Manual | © National Instruments | 15...

  • Page 17: Choosing A Pull-Up Resistor

    Choosing a Pull-up Resistor Choose a pull-up resistor that does not exceed the maximum current sink rating of the isolated outputs. The pull-up resistor must have a power rating that will not cause it to overheat. For example, with a 24 V output, a 2 kΩ resistor will cause a current sink of 24 V / 2 kΩ = 12 mA.

  • Page 19 For example, if the working distance of the imaging setup is 100 mm, and the focal length of the lens is 8 mm, then the field of view in the horizontal direction of an ISC-1780 is 0.0048 �� × 640 × 100��...
  • Page 20 The black level specifies the image brightness. Set the black level to the pixel value which corresponds to true black. If the black level is inaccurate, near-black pixels may be displayed as black or black objects may appear gray in the output image. ISC-178x User Manual | © National Instruments | 19...

  • Page 21: Acquiring Images

    There are multiple ways to adjust the black level: • MAX—Use the settings on the Camera Attributes tab of the device configuration page. • Vision Builder AI—Use the settings on the Advanced tab of the Acquire Image (Smart Camera) step. Look-up Table A look-up table (LUT) transformation maps pixel values in the source image into other values in the transformed image.

Beginning of Image Readout The trigger shown in the figure represents an external trigger, configured to use the rising edge as the active edge.
  • Page 24 In general, a longer exposure time or exposure delay results in a longer frame period, and a slower maximum frame rate, provided the trigger delay is not longer than the untriggered minimum frame period. ISC-178x User Manual | © National Instruments | 23...

  • Page 25: Exposure And Lighting

    Determining the Trigger Delay If the trigger delay is set longer than the untriggered minimum frame period, the trigger delay value further limits the minimum frame period. When the trigger delay is specified in time units, the software includes this in the calculation of the maximum frame rate indicator. Otherwise, the expected rate of the edges for the delay is not known, and you must determine the duration of the trigger delay.

    This introduces additional offset and jitter to the start of the exposure. ISC-178x User Manual | © National Instruments | 25...

  • Page 27: Reconfiguring During An Acquisition

    The Trigger Overlap feature defaults to Readout, which means Trigger Overlap is enabled, and allows an exposure to occur during the image readout of the previous frame. Change the Trigger Overlap behavior by setting the Trigger Overlap control in Vision Builder AI, setting the Trigger Overlap attribute in LabVIEW, or by setting the Trigger Overlap in the attribute tree in MAX.
