Adjusting External Lighting Timing
When you use a trigger delay, you must adjust the timing to turn ON external lighting so that it matches the
trigger delay timing.
Using a Strobe Trigger Signal to Control External Lighting
If a Sensor Data Unit is connected, you can change the output time of the strobe trigger signal (STGOUT) to
adjust the timing of the external lighting.

Preventing Mutual Interference of Multiple Sensors
When the same trigger signal is input to multiple Sensors, the lighting from one Sensor may affect the
measurements of the other Sensors. This is called mutual interference. This kind of interference can be
prevented offsetting the image input timing of each Sensor from when the trigger signal is received.
Example:
A trigger (i.e., the TRIG signal) is input to Sensor 0 and Sensor 1 at the same time.
Sensor 0 immediately begins image input when the trigger is input.
Sensor 1 begins image input after the specified time has passed.
