Functions
Gain
Manual Gain setting is available with this camera.
The variable range extends from 0 to 18 dB, and the
unit is designed so that the gain can be subdivided and
set to any of 512 steps.
At the factory default setting, the gain is set to 0 dB.
Shutter
This camera allows Manual Shutter setting.
The relationship between the parameter and the
exposure time is given by the following formulas.

P = Parameter (001h ~ C7ch)
E = Exposure time (

Trigger Shutter
Trigger shutter is useful for capturing images in
response to a trigger that starts the exposure to match a
preset timing. It can also be used to capture an image
using multiple cameras with the same timing. When a
trigger shutter is used, the required trigger is input via
the 4 pin connector on the rear panel. The input signal
is a 5-volt negative pulse. The falling edge of the
signal is detected as the trigger, and the unit is
equipped with an exposure time consisting of the
shutter parameter set as trigger mode 0, and trigger
mode 1 that controls the exposure timing using the
width of the trigger signal pulse. When trigger mode 0
is used, the minimum width of the trigger is 10
microseconds. When trigger mode 1 is used, there is
no limit to the exposure time.
This unit can also be used with a software trigger that
issues the trigger signal via a software command. Both
trigger mode 0 and trigger mode 1 can be used with
software triggers.
