Basler A504k - Free-Run Mode with Synchronous; Asynchronous Timing

Basic Operation and Features
3-22 Basler A500k Series
PRELIMINARY
3.3.4.2 Free-run Mode with Synchronous / Asynchronous Timing
Figure 3-20: Free-run, Programmable Mode - Exposure Start with Frame Valid High, Exposure
Stop with Frame Valid Low
If the exposure starts when Frame Valid is high and ends while Frame Valid is low (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 µs + z µs
