and there are different versions and cameras all around. So this device
only covers the absolute basics.
The IOC's operation is a bit arcane. Probably the most important part is the configuration state machine. As
the SET_PARAMS takes care of buffer allocations it might take some time,
as well as afull re-configuration is required every time we change the
binning, roi, etc... This is automatically performed upon starting an
exposure (if it heven't been done before).
The status flag state machine during re-configuration is:
