Overhead Delay
Overhead_Delay can range from 5 to 6
μ
s and depends on the internal operations of your
computer.
Exposure Controls
The camera can grab images in one of seven ways. The camera’s line rate (synchronization)
can be generated internally through the
Acquisition Line Rate
feature (a member of the
Sensor Control
set of features) or set externally with an
EXSYNC
signal, depending on
your mode of operation.
To select how you want the camera’s line rate to be generated:
1.
First set the camera mode using
Exposure Mode
and
Line Trigger Mode
commands.
2.
Next, if using mode 2, 6, or 7 (see below) use the commands
Acquisition Line Rate Abs
and/or
Exposure Time Abs
to set the line rate and exposure time.
GigE Vision Input Controls
Sensor Control
Exposure Mode
This feature is used to set the operation mode of
the Exposure (or shutter): Off, Timed, Trigger
Width. If Off is selected then the camera uses the
maximum time according to its line rate.
Line Trigger Group
Line Trigger Mode
The state of the line trigger. If the trigger is off,
then the line trigger is internally generated.
Otherwise, the line trigger is caused by an
external signal. Modes: Off or On.
Set the Exposure Mode
Sets the camera’s exposure mode and allows you to control your sync, exposure time, and
line rate generation.
