Configuring Exposure and External Trigger Settings
Configure settings related to exposure control methods and trigger control.
The factory settings are as follows. Change settings as necessary, according to the intended purpose
or application.
Factory default values
Item
Default value
Trigger Selector (trigger operation)
Frame Start
Trigger Mode
Off
Trigger Source (trigger signal source)
Line 5 - Optical In 1
Trigger Activation (trigger polarity)
Rising Edge (rising edge of input signal)
Exposure Mode
Timed (control via exposure time)
Exposure Time
13427 (µs)
Exposure Auto*

* This item is only enabled when [Exposure Mode] is set to [Timed].
Caution
When [Exposure Mode] is set to [Off], [Trigger Mode] cannot be set to [On]. Other settings may also be restricted
depending on the exposure mode, so be sure to set the exposure mode before configuring the trigger settings.

Set [Exposure Mode] to [Timed].
([Timed] is the default setting.)
* 1 The minimum value will differ depending on the [Pixel Format] setting value.
The actual exposure time will consist of the image sensor’s offset duration (13.7 μs) added to the
setting configured on the camera.
When [ExposureMode] is set to [Timed] and the exposure time is set to 7 μs, the actual exposure
time will be as follows.
7 μs + 13.7 μs (offset duration of image sensor) = 20.7 μs
When [ExposureMode] is set to [TriggerWidth], the exposure is slightly longer than the width of the
trigger signal. To achieve an exposure time of 20.7 µs and the exposure time offset is 13.7 µs, use
20.7 µs - 13.7 µs = 7 µs as the high or low time for the trigger signal.
