Trigger Signal Input

Trigger signals can be input via the 2nd, 3rd, 4th pins of the DC IN
connector, or the software command. Switchover of the trigger
signal can be changed via the TriggerSource register.

Trigger signal polarity
Positive refers to a trigger signal polarity activated while rising from
Low to Hi, or during the Hi interval.
Negative refers to a trigger signal polarity activated while falling
from Hi to Low, or during the Low interval.

Note
• When inputting a trigger signal to the camera using the DC-
700/CE, use DC 5 V or less at the logical high level.
• Make sure to supply power to the camera module and confirm
that the camera module is operating before inputting a trigger
signal. If you input trigger signal to a camera module without
the power supplied, this may cause a malfunction of the
camera module.

Trigger Modes

There are five modes, Free run, Bulk Trigger, Sequential Trigger,
Burst Trigger and Freeset squence.
Free Run
The camera operates without a trigger signal and performs the
video output operation continuously after the shutter (exposure) is
finished when operating in Free run mode.
• Trigger edge detection (Polarity: positive)

• Trigger width detection (Polarity: positive)

Bulk Trigger (except XCG-CG40)
Different camera setting configurations are stored in memory
channels beforehand, with the different settings applied to acquire
multiple video images at each trigger event. In the following
diagram, two images are acquired in one cycle.

Sequential Trigger (except XCG-CG40)
Different camera setting configurations are stored in memory
channels beforehand, with the different settings applied in
sequence to acquire a different image with each trigger event. In
the following diagram, two images with different exposure settings
are acquired in one cycle.

Burst Trigger
This is a feature capable of continuous shooting at the trigger
timing and specifying the number of exposures, exposure interval,
and exposure time. Select from the mode that repeats one
exposure time or the mode that switches between 2 exposure
times repeatedly. Furthermore, there is another mode that repeats
only while the trigger signal is on.
