These slider-edit controls permit manual adjustment of the camera settings
that determine the intensity and quality of the output image. In Auto modes,
these controls will automatically adjust themselves to the input beam intensity
conditions. The Ultracal operation will only adjust the Black Level while the
Auto Setup and Auto X operations can modify all of them.

Trigger
This panel only affects the electronic trigger features in the selected camera.
The camera must be provided with a low voltage TTL/CMOS input trigger pulse
to activate the external trigger feature. The Strobe Out is a low voltage
TTL/CMOS output signal that can be used to trigger a laser. Trigger options
are described below.
o
None The camera is operating in CW mode and will output frames
continuously.
o
Trigger In The camera will only start to expose and transmit a frame
of data when a trigger pulse is sent to the camera. If a delay in the
start of exposure time is needed, enter the delay time in the adjacent
edit box. Delay time is programmable in milliseconds.
o
Strobe Out The SP620 and SP503 cameras will
run in CW mode but issue a Strobe output pulse at the start of each
frame exposure time. Some cameras also offer a Strobe Delay and a
Strobe Pulse Width setting feature.
o
On-Board Photodiode The SP620 and
SP503 cameras have a built-in photodiode detector that can be used to
sync pulsed lasers without providing an external signal to the camera.
When this device is selected the camera will start a calibrate cycle
setting the photodiode detector to the room ambient lighting
conditions. During this calibration cycle, the laser must not be firing.
When the cycle completes the camera should be able to detect the
laser flash and trigger in sync with the laser pulses. If the room
lighting conditions change and the camera stops triggering reliably,
then this calibration cycle should be repeated by cycling back to
Trigger-None and then reselecting On-Board Photodiode.
