● 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.

- Trigger Input

(a) Negative

(b) Positive

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_WIDTH + ( Ton - Toff )

Trigger amplitude Toff [µs] Ton [µs]

+3.3V 2.92 26.2

+12V 2.12 31.2

+24V 2.12 31.2

* Toff and Ton are typical value.

* These values are changed in operating environment.
