Configuration of the camera

The ExpOffset field specifies the camera specific exposure time offset in
microseconds (µs). This time (which should be equivalent to
Table 65: Cam-
era-specific exposure time offset on page 194) 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.
