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. Where

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

E = (Int (P ⋅ 0.64) ⋅ 32.55) + 10 [∝s]

Setting examples

1 (001h) : 10 ∝s

48 (030h) : 0.99 ms

480 (1E0h) : 10 ms

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.
