Basic Operation and Features
3-16 Basler A500k Series
PRELIMINARY
3.3.3 ExSync, Programmable Mode
When using the ExSync programmable mode to control exposure, several guidelines must be
followed:
• ExSync must remain high for a minimum of 1 µs.
• ExSync must remain low for a minimum of 1 µs.
• Timer 1 must be set to a minimum of 10 µs.
• The minimum ExSync signal period is 2 ms with the full AOI for the
A504k/kc, and 13.52 ms
for the
A501k/kc.
• If the AOI feature is being used, the minimum ExSync signal period is equal to
1/Maximum Frame Rate where the maximum frame rate is determined by the
formula on page 35.
Assuming that these general guidelines are followed, the reaction of the camera to a falling
ExSync signal will be one of four cases, which are described in sections 3.3.3.1, 3.3.3.2, 3.3.3.3
and 3.3.3.4.

The FlashOut signal can be set into a mode where it is high while the actual expo-
sure is active. This FlashOut mode is shown in the timing diagrams.
