Delayed Readout; Counterandtimercontrol Function - JAI GO-5100MP-USB User Manual

Delayed Readout

Delayed readout allows images captured by a [FrameStart] trigger command to be stored
temporarily inside the camera (delayed readout buffer) and read out using a
[AcquisitionTransferStart] trigger after capture.This function is useful when executing triggers
simultaneously on multiple cameras.
Note
This function imposes a heavy processing load on the network bandwidth, as images from
multiple cameras are read out simultaneously. The number of frames that can be stored for
delayed readout depends on PixelFormat.
For details, see "Trigger Control" .

CounterAndTimerControl Function

The counter function counts up change points in the camera's internal signals using the
camera's internal counter, and reads that information from the host side. This function is
useful for verifying error conditions via the count value using internal camera
operations.Counting is performed at frame trigger, frame start, exposure start, and exposure
transfer end, and by comparing these values, you can determine the internal camera state at
which missed triggers will occur.
