Basler A504k User Manual

Basic Operation and Features
3-12 Basler A500k Series
PRELIMINARY
3.3.2 ExSync, Level-controlled Mode
When using the ExSync level-controlled mode to control exposure, several guidelines must be
followed:
• ExSync must remain high for a minimum of 5 µs.
• ExSync must remain low for 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 3.3.2.1, 3.3.2.2, 3.3.2.3
and 3.3.2.4.
3.3.2.1 ExSync, Level-controlled Mode with Asynchronous Timing
Figure 3-11: ExSync, Level-controlled Mode - Exposure Start and Stop when Frame Valid is Low
If the exposure starts end ends while Frame Valid is low (see Table for value n to x):
• The actual start of exposure is x µs later than the falling of the ExSync signal.
• Actual length of exposure time = n µs
ExSync signal can already go low up to 1 µs before FVAL is low.
*
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.
