Non-concurrent mode occurs when integration and readout are performed serially. In
concurrent mode integration and readout can overlap.
To set the exposure time, the camera must be operating in exposure mode 2, 6 or 10. If
you enter an exposure time outside of a valid range, the input will be clipped to the min
or max.
If you enter an exposure time which overlaps with the frame readout, the exposure time
will automatically adjust to integral units of exposure time increments. The camera sends
a warning when this occurs.
To select how you want the camera’s frame rate to be generated:
1.
You must first set the camera’s exposure mode.
2.
Next, depending on the specified exposure mode, set the frame rate and set the
exposure time.
