Fixed Trigger Shutter Mode
□
This is the mode to start exposure with external input trigger signals, and set the exposure time with
serial communication command.
□
Trigger operation is Clock-sync and H/V-sync Restart system.
□
The delay time (Exposure Time Delay) from detecting trigger edge in the camera to Exposure output
(TTL) differs in each mode mentioned below.

at trailing edge.
□
The min. setting value of Fixed Trigger Shutter Mode is 1H( min.).

Depends on each Tap mode and horizontal pixels

□
The next trigger can be accepted during outputting a current image. However, while the image output is not
completed, do not input the trigger signal of the image exposure settings to start the next output.
□
The camera ignores any trigger input between Exposure Time start and Read-out start. Refer to (A) in the drawing
below. When a read-out period (FVAL=1) and an exposure start-up (start-up of Exposure Time) overlap, LVAL and
DVAL output Lo for 4H, and also stop an image output.
