Field Name Definition
Use Focus Data
to Detect
Spacing
Violations When Profile mode is selected, select this check box to use focusing data and not
photoeye, to identify whether there is a spacing violation.
Fixed Focus
Value When Fixed mode is selected, enter the fixed focus value in the field provided.
This parameter indicates the fixed focus position used when the position sensor related
to the camera is not used. The possible values are from 0 to 32767 mm where 0 is the
farthest valid station reading distance from the camera. The default setting is 0.
0 (zero) is referenced from the camera sensor.
This distance must be greater than the
Far Working Distance (Z) set in the Device
settings>camera>mounting>automatic calibration parameters.
Trigger Extends
Leading Edge Enter the distance to extend the trigger phase beyond the leading edge of the package.
Trailing Edge Enter the distance to extend the trigger phase beyond the trailing edge of the package.

Focus, Gain,
Zoom Point Enter the distance to hold the latest focus, gain, and zoom.
Gain
Gain Mode Select Profile or Fixed from the drop-down list.
Tracking
Offset When Profile mode is selected, enter the tracking offset in the field provided.
The Height sensor can be positioned either above or below the 0 focus height as shown
in the figures. However it should not be positioned above the level of the tray/box. In this
case the tray/box would never be detected so the
Tracking Offset must be set to
compensate. This Offset then is added to the Percentage of Tray Depth to Set AF
therefore degrading the focus precision.
Fixed Exposure
Value
This sets a fixed exposure time to optimize the quality of the acquired image
