Basler A504k - Free-Run Mode with Synchronous Timing 2

Basic Operation and Features
3-24 Basler A500k Series
PRELIMINARY
3.3.4.4 Free-run Mode with Synchronous Timing 2
Figure 3-22:Free-run, Programmable Mode - Exposure Start and Stop with Frame Valid High
If the exposure starts and ends while Frame Valid is high (see Table for values n to z):
• Actual length of exposure time = n - x + y
The actual length of exposure time can only occur in multiples of z µs.
