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.
Trigger Selector (trigger operation)
Trigger Mode
Trigger Source (trigger signal source)
Trigger Activation (trigger polarity)
Exposure Mode
Exposure Time
Exposure Auto*
* This item is only enabled when [Exposure Mode] is set to [Timed].
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.
Adjusting Packet Size: With [Trigger Mode] set to [Off] and [Exposure Mode] set to [Continuous], clicking the
(Start Acquisition) button should produce a live image. If, however, you can only see a black screen, it may be the
result of the packet size setting in the camera being larger than the packet size setting in the GigE NIC or switch.
To correct the problem, you can either reduce the [Packet Size] setting to a value less than 1500 in the JAI Control
Tool (under [Transport Layer Control] / [Stream Channel Selector], or set your NIC or switch to support "Jumbo
Frames." This setting is typically found in the Advanced Adapter Settings for the NIC or switch which can be
accessed through the Device Manager on your PC.
■ Control via External Triggers
Configure the settings as follows.
Trigger Selector (trigger operation)
Trigger Mode

* 1 The maximum value for [Exposure Time] varies depending on the value configured for the [Acquisition Frame
Rate] setting and the [Pixel Format] setting.
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 1 μs, the actual exposure
time will be as follows.
1 μs + 13.7 μs (offset duration of image sensor) = 14.7 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 14.7 µs and the exposure time offset is 13.7 µs, use
14.7 µs - 13.7 µs = 1 µs as the high or low time for the trigger signal.
