The camera provides two exposure modes (ExposureMode):
OFF: The exposure time is automatically set to the maximum exposure time that maintains the configured frame rate (Exposure Time = 1 / Frame Rate).
In this mode, you cannot manually set the exposure time.
Timed: The exposure time can be manually set to a specific value.

Steps

To manually set the exposure time:
Go to RemoteDevice -> AcquisitionControl -> ExposureMode, and set it to Timed.
Then, go to RemoteDevice -> AcquisitionControl -> Exposure Time and specify the desired exposure time.

To set the exposure time according to the frame rate (Exposure Time = 1 / Frame Rate):
Go to RemoteDevice -> AcquisitionControl -> ExposureMode, and set it to OFF.
