Figure 4-10-3 External Frame Trigger Input Mask Effect
①
MaskTimeR: The time during which changes in the signal rising edge are
invalid
②
MaskTimeF:The time during which changes in the signal falling edged are
invalid
Using this function you can control the generation of unwanted frames due to
unexpected variations in the signal.
③
If you set MaskTimeR to too large a value, valid trigger changes may go
undetected and frames will not be generated, so set the value as small as
possible.
④
If you set MaskTimeF to too large a value, valid trigger changes may go
undetected and unwanted frames will be generated, so set the value as small
as possible.
