Basler A504k - Free-Run Mode with Synchronous Timing 1

Basic Operation and Features
Basler A500k Series 3-23
PRELIMINARY
3.3.4.3 Free-run Mode with Synchronous Timing 1
Figure 3-21: 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):
• The actual start of exposure can be x µs later than the falling of the internal control signal.
• Actual length of exposure time = n - y + z
The actual length of exposure time can only occur in multiples of w µs.
