Example of parameter list:
The exact sequence is:
Block-write (this needs to be a functionality of the underlying software stack
(e.g. AVT FirePackage). It may not be available for third party IIDC software
stacks.) of list to advanced feature address
Camera timing behavior is like this:
Standard Update (IIDC)
In the
Standard Update (IIDC)
mode single parameter are sent to the cam-
era.
•
Standard Update (IIDC)
shows same behavior as MARLIN
•
Parameter will be sent from host to camera and will be activated as soon
as possible without interruption of the transfer
•
If the host updates more than one parameter (without block write) the
parameters may become active in different images
•
Standard Update (IIDC)
can be combined with the new parameter
update timing modes

Table 44: Example of parameter list
Fast Parameter Update Timing
Quick Format Change Mode (QFCM)
After block write command is processed in the
camera all changed parameters are valid for the
available next image. Frame rate is constant.
After transfer of the parameter list via block write
a current transfer will be finished. A started expo-
sure will be interrupted until the microcontroller
has processed the list and copied it into the FPGA.
Exposure of the next image with new parameters
is started.
There may be a gap between two images.
