Note

• Exposure times entered via the 81Ch register are mir-

rored in the extended register, but not vice versa.

• Changes in this register have immediate effect, even

when camera is transmitting.

• Extended shutter becomes inactive after writing to a

format/mode/framerate register.

• Extended shutter setting will thus be overwritten by

the normal timebase/shutter setting after Stop/Start of

FireView or FireDemo.
