● I/O Timing
The received external trigger signal delays by internal circuit.
And LINE2 output delays from LINE1 output by the difference of internal circuit.

Fig. Trigger Signal Input Delay
EXT_TRIG_WIDTH: The pulse width of the external trigger input (more than 200μs).
Toff: The delay time of falling edge.
Ton: The delay time of rising edge.
TRIG_IN_WIDTH: The pulse width of the trigger signal which is received inside of the camera.
Negative trigger: TRIG_IN_WIDTH = EXT_TRIG_WIDTH - ( Ton - Toff )
Positive trigger: TRIG_IN_WIDTH = EXT_TRIG ( Ton - Toff )
