Setup Panel
Snap
Click the Snap button to acquire and display an image in the image window. You can use this to see how
camera settings affect the image, or to position objects within the camera’s field of view. The acquired image
is also displayed in the image display area of the Design and Display tabs.
Live
Click the Live button to continuously acquire images and display images in the image window until you
click the Snap or Live buttons. You can use this to see how camera settings affect the image, or to position
objects within the camera’s field of view. The acquired image is also displayed in the image display area of
the Design and Display tabs.
Image Source
The type of camera that is currently acquiring images.
Frames per Second
This field indicates the number of frames the device can capture and process per second. It is calculated
based on the current Shutter Open Time, Partial Scan line and Half Resolution Mode settings.
General Tab
Shutter
Shutter Open Time indicates the amount of time the shutter will be open. The longer the shutter is open (a
higher number), the brighter the image. A shutter open time that is too low can cause the inspected image to
be too dark. Higher shutter open times will decrease the number of frames per second acquired and may blur
the image. You can enter the value in the field or use the slider. The range of acceptable values is determined
by the camera type.
Dalsa Shutter / Exposure
The Dalsa camera is automatically configured for timed shutter mode. The shutter time, which can be
adjusted in VPM in Settings - Camera - General tab, is the exposure time PER LINE, just like the M5xx
cameras.
When the system is Online, the Line Trigger starts the exposure for each line, so it is very important that the
line trigger period be longer than the shutter time. If the line trigger rate is too fast, then some triggers will be
ignored.
When the system is Offline and you are using the Snap, Live, or Trigger buttons, the line triggers are inter-
nally generated by the camera at the rate of the shutter time. This allows you to acquire images without wir-
ing any inputs, although the images will be distorted because the line trigger rate is different. You can only
see accurate images when the system is Online.
Strobe Pulse Length (microseconds)
Enter the number of microseconds (from 0 to 500) that you want each strobe to be on. The strobe pulse
length must be coordinated with the shutter open time to provide optimum image capture and eliminate
image blur. (A zero value will turn the strobe off.)
