Field Name
Definition
Illumination Settings
Illumination
Pre-Power
Enable
Select the check box to enable. This puts the illumination in a power saving mode that
allows it to power up to full mode faster.
Illumination
Stay-On Time
Enter a value in seconds. This determines how long the illumination will stay on after the
end of the trigger cycle.
NOTE: If Direct Encoder is enabled in Modify Settings | Global
Settings | Operating Mode (see section 4.5.1), the Illumination
Stay-On Time needs to be greater than the amount of time the
conveyor will be stopped in a start/stop configuration.
Pulsed
Illumination
Enable
Select the check box to enable pulsed illumination and reveal the related option.
Pulsed Acq
Delay
Enter the Pulsed Acq (Acquisition) Delay in nanoseconds in the field provided. The
default value is zero.
This option is used to synchronize the illumination in an application where there are
multiple cameras in a tunnel and the illuminator lobes cross over the conveyor, possibly
causing interference (See 1.4). This allows the mounting structure to be reduced in size.
If a bright glare spot appears in the AV7000 Live Image Viewer when an image is
acquired, this may indicate interference of crossing illuminator lobes. Increase the
Pulsed Acq Delay value incrementally until the bright spot disappears.
Optics
CAUTION: After running the Calibration Wizard, changes should
ONLY be made to the DPI/LPI as directed by Datalogic Support.
Changing DPI/LPI may have a negative effect on the quality of the
image which my result in no reads.
DPI
Enter the minimum allowable DPI (Dots Per Inch) in the field provided.
This parameter expresses the minimum resolution (in the X direction) in Dots Per Inch
(DPI), supported by the camera. The minimum resolution is typically defined at the
maximum reading distance.
This field is automatically filled in during the static calibration of the unit but may be
changed during the dynamic calibration step
LPI
Enter the minimum allowable LPI (Lines Per Inch) in the field provided.
The LPI should match the DPI at the far scanning point. This matching of the DPI to the
LPI assures the pixels are not out of square, which can cause a no read.
Focusing
Focus Mode
Select Profile or Fixed from the drop-down list.
When Profile is selected, the light curtain, RangeFinder, or DM3610 will provide the
profile of the package.
