How to transfer parameters to the camera
The following 3 variants of transferring the parameters are available:
In the following you find a short description of each variant:
Encapsulated Update (begin/end)
The Encapsulated Update (begin/end) has the following characteristics:
• Host will set a parameter update begin flag in the camera (UpdActive
Field in Register 0xF1000570, see Table 140: Advanced register: Update
timing modes on page 282)
• Host will send several parameters to the camera and then signalize end
by resetting the flag
• All parameters will become active for the same next image
• Dependent on timing mode, the camera

Advantage ☺ Disadvantage
Encapsulated Update (begin/
end)
☺ easy to use (standard quad
writes in camera register is
possible)
one write access per register
access
Parameter-List Update ☺ only one write access for all
parameters
☺ fastest hostcamera transfer
(from 5 parameters on faster
than encapsulated mode)
☺ handling of parameter list
easy
not so easy to use (block
writes)
max. 64 entries for parameter
list
Standard Update (IIDC) ☺ compliant with IIDC V1.31 non deterministic change of
parameters
