Counter And Timer Control Function
This camera supports only the counter 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.
Six counters are available on the camera; Counter0, Counter1, Counter2, Counter3, Counter4
and Counter5.
The functions that can be counted are fixed for each counter.
Counter0: Counts the number of Line Trigger instances.
Counter1: Counts the number of Line Start instances.
Counter2: Counts the number of Exposure Start instances.
Counter3: Counts the number of Frame Trigger instances.
Counter4: Counts the number of Frame Start instances.
Counter5: Counts the number of Frame Transfer End instances.
When a problem occurs in a system that includes this camera, comparing the values from
multiple counters allows you to verify the extent of normal operability and can be useful when
investigating the cause of the problem.
