Basic Operation and Features
3.3.4 Free-run Mode
When using the free-run, programmable mode to control exposure, several guidelines must be
followed:
• The internal control signal must remain high for a minimum of 3 µs.
• The internal control signal must remain low for a minimum of 10 µs.
• Using full resolution, the minimum internal control signal period is 2 ms for the A504
2.485 ms for the A503
• If the AOI feature is used, the minimum internal control signal period is equal to
1/Maximum Frame Rate where the maximum frame rate is determined by the suitable for-
mula in section 3.11.1.
Assuming that these general guidelines are followed, the reaction of the camera will be one of four
cases, which are described in sections 3.3.4.1, 3.3.4.2,
The FlashOut signal can be set into a mode where it is high while the effective ex-
posure occurs, i.e. while the Integrate Enabled signal is high.
