■ Exposure times
Exposure times vary depending on the Tap Geometry and CL Pixel Clock settings. Refer to the
following table.

Control via External Triggers
When Controlling the Exposure Time Using Specified Exposure Times
Configure the settings as follows.
Trigger Selector (trigger operation)
Trigger Mode
Trigger Source (trigger signal source)
Trigger Activation (trigger polarity)
Exposure Mode
Exposure Time
Exposure Auto
* 1 Max. value = [Acquisition Frame Rate] - Max. exposure time value A ("Exposure times" (page 19))
1
Set [Exposure Mode] to [Timed].
([Timed] is the default setting.)
2
Specify the exposure time in [Exposure Time].
The setting value for the exposure time can only be changed when [Exposure Auto] is set to [Off].
If [Exposure Auto] is set to [Continuous], temporarily set it to [Off] before changing the [Exposure
Time].
3
Set [Trigger Selector] to [Frame Start].
([Frame Start] is the default setting.)
4
Set [Trigger Mode] to [On].
