Configuration of the camera

The ExpOffset field specifies the camera specific exposure time offset in micro-

seconds (μs). This time (which should be equivalent to Table 59: Camera-specific

exposure time offset on page 156) has to be added to the exposure time (set by

any shutter register) to compute the real exposure time.

The ExpOffset field might be zero for some cameras: this has to be assumed as

an unknown exposure time offset (according to former software versions).

Note



Time base can only be changed when the camera is in idle state

and becomes active only after setting the shutter value.
