Basler A504k - Exsync, Level-Controlled Mode with Synchronous Timing 1

Basic Operation and Features
3-14 Basler A500k Series
PRELIMINARY
3.3.2.3 ExSync, Level-controlled Mode with Synchronous Timing 1
Figure 3-13: ExSync, Level-controlled Mode - Exposure Start and Stop when Frame Valid is 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 ExSync signal.
• Actual length of exposure time = n - y µs ... n + z µs
The actual length of exposure time can only occur in multiples of w µs.
