Exsync, Programmable Mode - Basler A500k User Manual

Basic Operation and Features

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 A504
for the A501
• 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,
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.
