12  Configuration of the camera 
All camera settings are made by writing specific values into the corresponding registers. This 
applies to both values for general operating states such as video formats and modes, exposure 
times, etc. and to all extended features of the camera that are turned on and off and controlled 
via corresponding registers. 
The interoperability of cameras from  rers is ensured by IIDC, formerly DCAM 
(Digital Camera Specification), published by the IEEE-1394 Trade Association.

Writing and reading to and from the register can be done with programs such as “FireView” or by 
other programs t an API library(e.g. FirePackage).

This requires, for example, that to enable ISO_Enabled mode (ISO_Enable / Free-Run), (bit 0 in 
register 614h), the value 80000000 h must be written in the corresponding register.
