Exposure Timing With Positive Polarity Trigger Signal - Omron STC-BBS2041POE-BC Product Specifications And User's Manual

Exposure Timing with Positive Polarity Trigger Signal

Trigger Signal
(Positive polarity)
Trigger signal with
camera internal delay
Exposure Time
Exposure Time T1' = (CEILING (actual trigger width / 43 µseconds) x 43 µseconds + 258 µseconds + A
CEILING: Returns crossest number to be converted absolute value on multiple number of Reference value.
In other words, returns Quotient of division + Remainder (Remainder = 0: 0, Remainder ≠ 0:1).
A: 2.902 µseconds
e.g.
Case: Trigger width 50 µseconds on STC-BCS2041POE-BC
CEILING (50 µseconds / 43 µseconds = 1.16279)
CEILING = 1 + 1 = 2
T1' = 2 x 43 µseconds + 258 µseconds + 2.902 µseconds = 346.902 µseconds
Note 1: The trigger signal will be removed by filtering if active pulse width of input trigger signal is less than
"LineDebounceTime" setting time. Please input trigger signal has more than "LineDebounceTime" time
active pulse width trigger signal.
Note 2: Please refers "External Hardware Trigger Input Delay" for more details about "External hardware trigger
delay".
Note 3: Please refers "External Hardware Trigger Input Delay" for shortest active pulse duration of trigger signal.
