Exsync, Programmable Mode With Asynchronous Timing - Basler A500k User Manual

3.3.3.1 ExSync, Programmable Mode with Asynchronous Timing

Figure 3-15: ExSync, Programmable Mode - Exposure Start and Stop with Frame Valid Low
If the exposure starts and ends while Frame Valid is low (see Table for values n to y):
• The actual start of exposure is x µs later than the rise of the ExSync signal.
• Actual length of exposure time = n µs + y µs
ExSync signal can already become high up to 1 µs before FVAL becomes low.
