Specifications
ROI frame rates
Values were calculated as defined in Specified values on page 51.
To reach the maximum frame rate available for this setup, the bandwidth for image
traffic is 375 MBps. Increasing the
DeviceLinkThroughputLimit value does not
increase frame rates.
When rolling shutter cameras are operated in triggered mode, the values for
maximum frame rate reached in free run mode are cut in half.
