My camera is a FLI Proline, with KAF 6303E chip in it.
When I focus I want to change come camera options, I'd like to set the download speed to 4MP/s and turn off the RBI flushing.

I can do this by switching "Exposure Presets".

I'd like to do this because it really speeds up focusing.

But during image exposures I'd like to download at 1MP/s and I'd like RBI flush turned on.

I can do this by switching to another "Exposure Presets".

It would be nice to be able to do this.
